    Hi all,

    I just started using a new virtual machine on my VMware Workstation. Its worth to mention that i have other VM on the station and they are working fine but for some reason on this one i got those two errors and some warnings. I tryed to google it but i didnt find any specific answer. I hope you can somehow help me. I posted down below in the attachment sector photos of the errors with logs.

    Thank you in advance

    I solved this problem by downgrading to 15.5.6 . Why does that happen on 16.xx.xx no idea

    There was a major change in 16.x in how virtual graphics were handled (sandboxed) and it also added support for DX11 in Windows VMs. The mksSandbox process does not exist in versions prior to 16.x

    From the vmware.log it looks the compatibility is set to 12.

    2021-03-30T08:41:44.849+02:00| vmx| I005: DICT         virtualHW.version = "12"

    Have you tried setting the virtual HW version to 16.x compatibility when running with Workstation Pro 16.x?

    This may be a dead thread, but I had a similar problem and found that simply disabling "Accelerated 3D Graphics" in ((Virtual Machine Settings> Hardware> Display> 3D Graphics)) allowed me to avoid these crashes and specific errors.

    Thanks hsaqallah,


    I encountered the problem while trying to edit videos with Lightwork. I haven't tried the proposed solution of disabling 3D acceleration but my guess is that it'll work. Although it hurts to disable it!. I hope VMWare addresses it soon.

     


    worked for me too on VM Player 17. Thanks for sharing.

    Thank you very much for this. I am using 17.0.0 build-20800274, and I got this error. Disabling Accelerate 3D graphics resolved this issue.

    I got this problem when I trying to install Windows 11 VM on a Windows 10 host.

    I ran into this exact problem with VMWare 17.0.1 on Linux Pop!OS 22.  I really thought I was going to have to find another VM solution.  Thanks for this suggestion!!

    I created a clone of a migrated VM to 16.2, but the shrink failed with the same command. As suggested on this thread, I had to disable the 3D graphics to run "sudo vmware-toolbox-cmd disk shrink /".

    November update is triggering this exact issue for me in Windows 11.  I can confirm that disabling 3D Acceleration in the VMware settings for my Win11 vm works.

    Obviously not an ideal solution because I need acceleration...

    I also have the same problem, just upgraded to 16.2.1 and still have it. It's when I do a disk shrink then I get:

    mks ISBRendererComm: ISBRendererComm Remote Disconnect: socket closed.
    mks The vmx lost its connection to the mksSandbox.
    mks The mksSandbox process may have crashed or hung.
    mks Check the mksSandbox.log and vmware.log for more details.
    mks PANIC: ISBRendererComm: Lost connection to mksSandbox (2878)
    mks CoreDump_CoreDump: faking exception to get context

     I can consistently reproduce it when I have 3D graphics enabled when doing a disk shrink via command line inside a Windows 10 VM.

    "C:\Program Files\VMware\VMware Tools\VMwareToolboxCmd.exe" disk shrinkonly

     As soon as I disabled 3D graphics it stopped crashing.

    I get the same error on Ubuntu 20.04.3 with Workstation 16.2.1 and 16.1 before that. Needless to say that it worked like a charm on 15.5.7. For some reason it takes ages to recover memory file from a mounted iSCSI share on 10Gbps network. I can see network I/O spiking back and forth in bursts up to maximum supported bandwidth. By the time the memory dump is restored, MKS sandbox probably timeouts. After the crash, if I click restore from saved snapshot again, it will restore in a few seconds and will work all day without any issues.

    I too encountered this issue, immediately after upgrading to 16.2.1!  So, I downgraded Workstation Pro back to 16.1.2 (what I'd previously had), and my VM is again working!  VMware seems to no longer have good regression testing, suggesting that they and/or the company's software engineers / QA folks are of a lower grade than in the past.  VMware needs to get its act together!

    I encountered  this problem as well. My story is that I upgraded to 16.2.1 from 16.2.0, with a VM that had the HW upgraded.

    Disabling 3D accelration enables me to access the VM. It looks to me that So this is a bug introduced with 16.2.1.

    My setup is:

    Ubuntu 20.04.3 LTS, kernel 5.11.0-40-generic
    I'm using secure boot and got the modules signed and all well there.

    If I understand things correctly one need the 3D accelration in the VM to have it pass the "win 11 upgrade test".

    I was a happy user of VMware Workstation on OpenSUSE 10 years ago.

    Since our ways have parted, and everytime I've evaluated it in order to return to VMware, it fails like this.

    I'm now running Ubuntu 21.10, and I've now spent almost a whole day trying to get a useful installation.

    I'm running it on a Lenovo Carbon X1 gen. 6 with Core i7 CPU, 16 GB RAM, and 500 GB SSD. I've created a fresh Win10 install with 2 CPUs, 4 GB RAM, 60 GB disk fully allocated from the beginning - and yet you have to wait literally for minutes for response when you click something in the GUI.

    Neither this time will VMware win me back as a customer.

    What version of Workstation are you using?  

    There have been lots of reports of issues with 16.2.0 and 16.2.1.  Have you tried 16.1.2?

    I'm running 16.2.1 build-18811642.

    Would a downgrade be worth a try?

    Downgrading to 16.1.2 helped a lot - but my 3D app still runs a lot slower than using Wine directly on Linux.

    3D acceleration would surely help.

    I have met the same issue when a dialog box pops up too long at startup without selecting by me.

    Maybe the mksSandbox thinks the connection to vmware-vmx has been timeouted.

    Looks like version 16.2.2 is out. Has anyone tried to see if that works. I am running out of energy to keep trying new versions, which never work.

    16.2.2 still requires that you disable 3d acceleration before doing the shrink operation.

    Confirming issue still exists  with 16.2.1 build-18811642

    I wish that VMware's help messages were more helpful.

    I encountered the problem while trying to edit videos with Lightwork. I haven't tried the proposed solution of disabling 3D acceleration but my guess is that it'll work. Although it hurts to disable it!. I hope VMWare addresses it soon.

    I might depend on which version of VMware you have installed. Version 16.2.1 does not work for me, even with 3D disabled. I have to run 16.1.2. I have not yet tried version 16.2.2 though..

    mks is crashing from a panic and says it is creating a coredump, but it does not actually create one:

    Same issue with 16.2.2 and Debian 11. Crash (even with 3D option disabled) and corrupt the VMDK file. Need to reinstall all.

    I've waste 1 day with VMWare and I need to progress in my work. I will switch to another solution.

    Previously I used v15 and Debian 10 without problem.

    Good luck, but v16x seems to be an important regression.

    Hi all,

    In our Company we are useing Siemens Field PG 5 for Programming Software like Simatic Manager and Tia Portal.

    We have the same Laptops, but at some colleagues the VM crashes and at some clleagues it doesn't crash.

    Workstation 16 Pro

    VM Software Version 16.2.2 build-19200509

    The VM Tools are up to date.

    I read a lot about downgrading to 16.1 / or even 15.5

    Could this be really the case?

     

    In mksSandbox these following logs are posted.

    It seems to be a problem with VMware on windows only. I am running VMware Workstation 16.2.3 om my Mac at home, with 3D graphics and all enabled, with no problems at all.

    If I run the exact same virtual machine on my windows 10 PC at work, any VMware Workstation installation newer than 16.1.2 will crash - even with 3D graphics disabled, and it only works on 16.1.2 because I have 3D graphics disabled.

    I am considering moving to Virtual Box or qemu, to see if I can get better stability than VMware can provide.

    tl;dr for anyone looking for a better/different workaround than disabling 3d acceleration: try switching from Nvidia to Intel integrated graphics. Doing this allowed me to continue using 3d acceleration.

    I stumbled upon this issue while upgrading my ubuntu 20.04 kernel from 5.13 to 5.15 via the linux-generic-hwe-20.04 package (i.e. the package that provides the ubuntu 22.04 kernel to ubuntu 20.04). After upgrading, I ran into an issue where vmmon was not compiling correctly with the new kernel 5.15 headers. That issue was described here: https://communities.vmware.com/t5/VMware-Workstation-Pro/VMware-16-2-3-not-working-on-Ubuntu-22-04-LTS/m-p/2905535#M175399

    Instead of installing the kernel modules built from the vmware-host-modules github repo linked in that issue, I decided to upgrade my vmware workstation version from 16.1.2 to 16.2.4 and see if the error went away. To my relief, vmmon was able to compile, and I was able to start VMs again.

    However, after starting a VM, it would hang for a while, and then eventually show this same `MKS -RendererMain` error. Indeed, disabling 3d acceleration would allow for the VM to work as normal.

    Given that I started having these issues originally from my kernel 5.13 to 5.15 upgrade, and that I know ubuntu 22.04 uses both kernel 5.15 and wayland by default, I guessed that the issue of 3d acceleration not working was related to this. In ubuntu 22.04 the stack would be kernel5.15+nvidia+wayland, where my stack was kernel5.15+nvidia+x11. I used `prime-select intel` to switch from my nvidia GPU to my intel integrated graphics, and was able to start my VMs again successfully.

    I have a Dell Precision 5510 laptop, with a Nvidia Quadro T1000 Mobile discrete graphics card. My VM was running Windows 10. And as previously stated my host machine was Ubuntu 20.04 w/ linux-generic-hwe-20.04 installed.

    Looks like my theory about my issue being related to the wayland upgrade was at least partially right. I ended up finding this article: https://wiki.vi-toolkit.com/index.php?title=Vmx_hacks&mobileaction=toggle_view_desktop#Linux_Host_-_switch_back_from_Vulkan_to_X11

    I added this to my `~/.vmware/config` file, and was able to continue to use my Windows 10 VM with my nvidia GPU and 3d acceleration enabled:

    ```
    mks.enableX11Presentation=TRUE
    mks.enableVulkanPresentation=FALSE
    mks.enableVulkanRenderer = "FALSE"
    mks.enableGLRenderer = "TRUE"
    mks.vk.allowUnsupportedDevices = "TRUE"
    mks.forceDiscreteGPU = "TRUE"
    ```

    16.2.4 build 20089737 has the same behavior when running  Linux 5.15-46 on 5.15.0 ... both with Wayland (Ubuntu on Ubuntu-Studio) ... however

    I noticed that the Virtual Machine had 4GB RAM but the Graphics Memory 8GB ...

    Then, without disabling the 3D Graphics, I defined 8GB RAM and 2GB of Graphics Memory and it seems that works.  Just that a remote VNC connection freeze, but could be a different issue.

    Thanks strudels. I added these lines to my vmx on my Debian Buster host with Nvidia Quadro RTX4000 and Windows10 VM. This allowed me to launch the VM without hanging and with 3D acceleration on. Great result and the performance is on a par if not slightly better than with Virtualbox.

    It's happening on Workstation 16.2.4 running on a Windows 10 host with Intel integrated graphics, so it's not likely to be an NVidia issue, at least not on Windows (which makes it unlikely on Linux, I think).

    So I encountered this MKS during upgrading my guest Windows 10 to Windows 11 (although 3D HW Acceleration was turned off.) But the error was happening on a specific VmwarePlayer instance (I have the latest 16 version). Other instances were fine. For the faulty instance, I tried defragmenting and compacting the main vmdk hard drive (from the VMWare Hardware -> Hard Disk screen.) Then I did chkdsk /f /r on the host windows machine on the drive that has my vmdk files. Interestingly, chkdsk found some free space related errors and fixed them. After that, my guest upgrade to windows 11 worked. Not sure what step fixed it.

    Count me amongst those for whom this is a solution.  I'm not normally doing anything in the VMs that would use 3D graphics, the loss is unimportant.

    I noticed a strong pattern--it would blow up when the system was otherwise heavily loaded or otherwise not responding well.  (When a program wanted to update itself--I think it did a restore point before updating, took out a VM.)

    For all the folks, who can reproduce this error: Are you sure this is not a Windows/graphics driver issue?

    - There is a "feature" in Windows, that unresponsive GPUs are reset after a timeout. (TDR - Timeout Detection and Recovery, https://learn.microsoft.com/en-us/windows-hardware/drivers/display/timeout-detection-and-recovery)

    - Shared GPU memory means that GPU memory can actually be paged out.

    - During paging, GPU call latency is enormous.

    - Observing a call not responding within a reasonable time, Windows can decide that GPU is frozen and resets it.

    I have seen this many times, also during excessive (normal) process swapping, too. Then you get MKS disconnection, etc.

    When you disable 3D acceleration, you are not using the GPU's resources as heavily.

    Could you please try installing the latest graphic card driver, and also change the timeout value? Please see: https://answers.microsoft.com/en-us/windows/forum/all/increase-time-out-limit/e979e2ad-e15f-450b-9818-a148cbf01078

    I saw this disconnect many times, and haunted me for awhile. It happened with Win10, RTX2070 and RTX3070Ti, when not using Workstation on Hyper-V. When using Workstation with Hyper-V, these errors got very rare. I cannot reproduce this error myself deterministically. My best way to crash VMware is having a large RAM Ubu22 guest VM (32 GB on a 64 GB machine), that starts with lots of I/O on NVMe, and starting Firefox with a page that uses a DRM video decoder (Netflix is the winner, but DisneyPlus works, too). I checked with the Firefox guys, reported bugs, etc. but it seems that although there is a correlation, the error seems to be an OS issue.

    Could you also please look for any errors in Event Viewer after these disconnects? Thank you.

    Hey guys,
    I'm assuming it's an error, but after a lot of trying I found the solution:
    Add "mks.dx12.vendorID = "0x10de"" to .vmx file and the vm also can use with accelerate 3d graphics. (The vondorID describes the (i)gpuID and shown in the device manager.)
    Please try.

    encountered same issue when upgrading from VM Workstation Player 16 to 17.0.0 and my WinXP VM could not be started anymore due to subjected Error. While running chkdsk on particular .vmdk did not help, eventually disabling 3D graphics acceleration in particular VM's Hardware > Display settings did.

    I'm on Workstation 17.0.2 on an HP EliteBook 850 G5.  I'm having the same problem in a Windows 7 VM.  Problem is that disabling 3D acceleration also disables the Windows Aero theme.  This really pisses me off.  For a program that I pay for, I would hope that there would be a better fix for it by now.  It's been two years.

    I've even tried downgrading VMware Tools version to 10.3.5, and same thing.  Downgraded the hardware compatibility to version 15.x, same thing.  It's one thing if all I need to do is install the VM as HW version 15 off the bat.  But I have a couple of Win7 VM that I made a couple of years ago, and that would mean that I would have to reinstall them outright (I've upgraded their hardware versions).  One is a cloned physical disk, and I really don't want to have to do that again if it starts having the same problem.

    Edit: Sorry for being snarky and crappy.  Was uncalled for.  I had just figured out how to get my Vista VMs to work properly, and then started having problems with Windows 7.  just big grimace.

     

    Edit: So far, downgrading hardware version to Workstation 14.x (if 15.x doesn't work) and reducing GPU RAM seems to work so far.  But this should still be fixed.

    @BadOmen, this is a generic error message -- there is not one issue that triggers this error message -- but lots of different and new issues -- often due to D3D12 driver issues.

    To understand and fix your particular problem, we'll need vmware.log and mksSandbox.log files, and a description of what was happening in the guest when the error happened.

    Per https://support.hp.com/gb-en/document/c05903028 the HP EliteBook 850 G5 has a Intel UHD Graphics 620 and an optional discrete AMD Radeon R59.  Does your system has the optional AMD GPU?

    No it does not.  It's definitely a graphics issue, given as I'll open an app like Chess Titans to test on Win7, and that will do it.

     

    Downgrading the HW version of the VM and reducing GPU RAM to 1 or 2GB seems to help so far.

    Hello.  So I built a test VM, upgraded to HW 17.X and most recent VMware Tools.  3D acceleration enabled, and 1GB GPU RAM.  4 Cores CPU, 4GB RAM, SATA drive.  I went in to a built-in Windows game like Chess Titans, and it crashed within a minute.  I attached the files in the zip.

    Also, Sorry for being snarky and crappy. Was uncalled for. I had just figured out how to get my Vista VMs to work properly with an older version of VMware Tools, and then started having problems with Windows 7.

    So before upgrading that VM to 17.X, I originally built it for HW 15.X.  So I copied a backup, and ran that.  Crashed as well (logs attached).  However, downgrading to HW 14.X, and no problems so far.  Played some games that used graphics, etc.  No problem.  So it looks like Windows 7 with 3d acceleration enabled needs to stay at HW version 14.X so far.

    I also still have this issue on VMWarePlayer v17.5.0. For whatever reason, PrusaSlicer seems to most often aggravate the issue on launch, but it can happen at other times too.

    Info on environment:

    • VMWarePlayer (licensed version) v17.5.0
    • GPU: Intel ARC A370M / Intel Iris Xe
    • Host OS: Windows 11
    • Guest OS: Ubuntu 23.10

    I've tried just about everything at this point:

    • OpenGL rendering:
      • Seems to work stability, but there are major drawing artifacts that make 3d accelerated apps basically unusable
    • Change Graphics memory size and number of vCPUs in VM
      • Seems to have no effect
    • DX11 rendering
      • MksSandbox wont do DX11 rendering on my system
    • Disable acceleration
      • Seems to work, but this givens unacceptable performance for the apps I need.

    I have a paid license for VMWare player and really hope that VMWare can address this issue in an update soon. This makes my workflow miserable.

     ,

    Thanks for reporting this issue.  I've filed a bug internally.  The fact PrusaSlicer is free and open-source will hopefully enable us to reproduce the issue internally, and that's generally the quickest way to resolve this sort of issues.

    It would help us if you could provide the vmware.log and mksSandbox.log files that are on the VM directory, immediately after the crash.

    Could you also confirm exactly what did do when you tried "OpenGL rendering"?

    thanks for the prompt reply.

    > It would help us if you could provide the vmware.log and mksSandbox.log files that are on the VM directory, immediately after the crash.

    Attached are the vmware.log, the mksSandbox.log as well as coredumps from right after a crash of launching PrusaSlicer.

    > Could you also confirm exactly what did do when you tried "OpenGL rendering"?

    I added the following snippet to my VMX file:

    mks.enableDX11Renderer = "FALSE"
    mks.enableDX12Renderer = "FALSE"
    mks.enableGLRenderer = "TRUE"

    I have confirmed that MksSandbox is using the OpenGL renderer by looking at the logs with the above settings.

    Also attached is a screen shot showing some of the OpenGL rendering artifacts. It often doesn't draw everything depending on the mouse position or the position of other windows.

    If there is anything else I can do to help your search let me know. I've been a VMWare user for many years, and I'll be very grateful if you can help me get my workflow back to how smooth it was in the past.

    One side question: I've tried to get DX11 rending working thinking that might be more stable. However, when I disable DX12, MksSandbox tries to spin out DX11 but claims there is no compatible interface. Am I barking up the wrong tree to try this out as a work around?

    Edit:

    One other note: the guest OS is actually XUbuntu 23.10, not plain Ubuntu 23.10. I don't think this should make a difference, but XUbuntu still uses X11/Xorg where Ubuntu uses Wayland. Again, I don't think that should be an issue here as I've seen this type of crash on Ubuntu as well, but thought I'd point it out since the display server is interacting with the accelerated graphics.

    > I've tried to get DX11 rending working thinking that might be more stable. However, when I disable DX12, MksSandbox tries to spin out DX11 but claims there is no compatible interface. Am I barking up the wrong tree to try this out as a work around?

    DX11 renderer is still around, but there's an accept/deny-list restricting its use to older GPUs.  For two reasons: 1) because we want to eventually transition away from it,  2) because we run troubles when using DX11 renderer with new GPUs.  In fact, I believe we ran into troubles precisely with newer Intel GPUs like the you have.  So generally, DX11 is not a sustainable solution going forward, particularly for the HW you have.

    OpenGL renderer is also around, but it's also mostly for diagnosis purposes, as it too has many issues, particularly on Windows hosts and Intel HW.  DX12 and Vulkan renderer are the ones we're focusing on, and we are keen on addressing any issues.

     

    BTW, from the crash message, the issue looks like it could be coming from the Intel GPU crashing/resetting somehow.  Your system has two GPUs, and the crash happened with the discrete Arc GPU.  You could see if switching to the internal Xe GPU helps, by setting `mks.dx12.gpuPreference=MinPower` setting to the .vmx.

     

    One more thing, could you please point us to a freely available 3D model we can use PrusaSlicer to repro this, and explain which operations trigger the crash?

    Thanks for the info on DX11 and OpenGL. It looks like the only way out of this one is through it. Is Vulcan an option on Windows? I'm less familiar with that so don't really know if that's a silly question or not.

    No model is needed to reproduce the problem in PrusaSlicer. It doesn't crash every time, but if it does it will do so before the splash screen goes away so you don't need a model to load. I'll work on a minimal reproduction steps with a fresh VM on Ubuntu and specific steps and versions of software to help you debug this. It'll take me a couple days to get time for that, but I'll post back here when I get it.

    I'll also try out targeting the Iris Xe and see how that goes. Obviously performance wont match the Arc, but it'll be interesting if it doesn't have this issue. I'll also report back on how that goes.

    Last note, this is top notch customer support. I didn't expect such detailed engagement directly from the engineering team. I truly appropriate it, and whether or not we crush this bug it makes me want to stay a VMWare customer into the future.

    Thanks for the updates.

     I'm glad to hear it.  Our team is monitoring these Workstation/Fusion forums.  Not only we like to do good by all our customers, but the Fusion and Workstation users in particular provide us an exposure to a wider range of 3D applications than we could ever discover by ourselves, and therefore fixing these issues and incorporating the applications on our test suites enables to steadily improve the quality across all our products.  3D graphics APIs are vast and complex interfaces, so test coverage is the only road for quality, this applies not only to our drivers, but also the 3rd party HW vendor drivers too.  Unfortunately not all issues reported on these forums are easily reproducible and things sometimes do fall through the cracks.

    My colleague,  will take it from here as I'm not directly working on the component in question.

    and  

    Thanks again for great support. I have been running with DX11 rendering now since the last post and have not had a single crash (feels so good). I'm still trying to find the time to get a minimal repro example and will post that here when I get it. In the meantime, let me know if there is any other info I can provide to help with your debugging.

      I had a chance to confirm a minimal repo on this issue. below are the steps I took:

    * Install Ubuntu 23.10.1
    * Defaults for everything in the VM creation (VMX included in attached zip)
    * Defaults in the entire Ubuntu install process
    * boot up and login
    * Install prusa-slicer
      `sudo snap install prusa-slicer`
      At time of writing this was 2.7.1
    * Launch prusa slicer from the app launcher
    * Mine crashed on the first try at startup of the app (after a couple clicks about SSL configuration and skipping 3d printer setup)
      * If it doesn't crash on first try, try launching more instances of prusa slicer in rapid sucession without closing them. This usually triggers a crash for me within 3 instances.

    Attached ate the VMX, and logs to help.

    I'm on a Dell XPS 9530 with an Intel ARC A370M.

    Let me know if there is anything else I can do to help your debugging and thanks again for looking into this. Also, I've had zero crashes with the DX11 render since I last posted for reference.

     Thank you. I will try and reproduce the issue on my local system.

    I just tried `mks.dx12.gpuPreference=MinPower` and confirmed that MksSandbox does indeed select the Iris Xe. Interestingly I still got the crash on my first try launching PrusaSlicer. Logs and dumps attached.

    Yes, it's worth giving DX11Renderer a try as a workaround. Here are the VMX config options that force-enable DX11Renderer:

    mks.dx11.allowUnsupportedDevices = "TRUE"
    mks.enableDX12Renderer = "FALSE"

    Those settings did allow me to use the DX11 renderer with my Arc A370M. I tried launching multiple copies of PrusaSlicer which usually gets me a crash if it's going to happen, and so far no crash. This obviously isn't a great long term solution as DX11 will be going away and there are a couple small (but very manageable) rending artifacts, but if this gets my workflow stable while a fix is in the works for DX12 I am eternally grateful.

    I still need to find some time to build a minimal repro setup and will post that here when I get a chance. Thanks again to you and your team for the help. I know how hard it is chasing hard to reproduce customer issues.

    Using OpenGL renderer seems to work for me as a workaround when running VMWare WS 17 in Windows 11.
