IOMMU fault type 5

[SLCK]

Hi,

I've encountered an issue on ESXi 6.5 U1 where my vm would just power off randomly. The error i'm getting on the event log is VMware ESX unrecoverable error: (vmx) PCI passthru device 0000:86:02.0 caused an IOMMU fault type 5 at address 0x10d24a000). After that, any vm with that pcie device would not power on. Has anyone encountered this before? or does anyone know what IOMMU fault type 5 relates to?

Regards,

Sheen

Please send your hardware specifications (Details) and also ESXi build number.

Also let us know that what's the guest OS and virtual machine configuration as well.

hello,

i also have a firepro s7150 (s7150x2).

i have exactly the same problem.
did you find any solution for that?
googled for hours and tested all settings:

• pciHole.start 2048..
  pcihole.end 3072...
• firmware=“efi"...
• pciPassthru.use64bitMMIO="TRUE"
• pciPassthru.64bitMMIOSizeGB = “128"

nothing worked... my win10 64 bit vm always restarts when i install the "win10-64bit-radeon-pro-software-enterprise-18.q1.1-march22.exe"

i allways got hte error: "(vmx) PCI passthru device 0000:8d:02.0 caused an IOMMU fault type 5 at address 0xfffff5f000.  Powering off the virtual machine.  If the problem persists please contact the device's vendor."

can anybody help me?

thanks.

Hi,

I've got the same message :

2018-06-11T19:01:21.520Z| vmx| I125+ PCI passthru device 0000:00:02.0 caused an IOMMU fault type 5 at address 0x3a11728000.  Powering off the virtual machine.  If the problem persists please contact the device's vendor.

Interesting part if that it has worked for several weeks before a reboot (no configuration change). I've used the GPU without issue.

And now, it's impossible to boot the machine. I use a CentOS 7 guest VM, the VM poweroff just after grub loader.

I've used ESXi 6.5.0 and try to upgrade to ESXi 6.7, same issue with same error message.

I've a setup a new VM CentOS 7 with EFI, same issue with passthrough enabled.
