Sudden VM console keyboard input failure of the 6.7.0 Update 3 hypervisor.

[wannavm]

Not sure what went wrong, but all of a sudden, I can't use my keyboard to control any VMs via their web console.

Using the latest chrome normal keys (a-z,0-9) do not generate any response from the vm, whereas up and down keys scroll up and down on the console's history, even if the VM is showing a setup screen which normally would intercept these inputs.

While using non chromium MS edge, keyboard inputs work as they should.

Looking at the developer console (both edge & chrome), I see many errors for "Unknown class found TooManyWrites" that is triggered from main.js

Any idea what could have gone wrong? This setup was working before.

Followup: seems the issue mainly impacts linux style systems, with or without vmtools. Virtualized windows responds to keyboard / mouse inputs normally, no matter the browser. TooManyWrites errors is still recurring, even with a windows session. Not sure if it is related or not.

Hi to everyone

I don't know if mi issue is the same as above ....

I have an ESXi 6.7.2 running on an HP DL560 Gen9 Server with a Ubuntu VM.

The VM Console was working fine without any problems but now I can write to the console from the VM (via echo TEST > /dev/console)but I am unable to see the echo of what I type in the console using the keyboard, so I cannot use it anymore ...using ssh in order to connect to the VM is OK.

I have done some Network tuning but I have also tried to update from 6.7.2 to 6.7.3, but the process got an error (now I don't remember ...). The actual is still version 6.7.2.

I have tried to start another VM but the problem still persist (I have also reboot the Server and ESXi)

Any idea of the cause of this issue ?

Thanks in advance

Marco

EDIT I am using Chrome Web browser and the issue is present only in the console launched from the ESXi Web management. One of the things that I have changed is the switch from Firefox to Chrome... I will try to check with Firefox..

were you able to find a fix for this, I am seeing this behavior on all my Ubuntu VMs

I had similar issue while trying to type in the console on linux vms (windows worked).  Found out, I must have hit pause break button on my keyboard.  Hit pause break and try again!

[RoyMerritt]

Thanks so much I was losing my mind wondering how all input could have suddenly broken with absolutely no changes but hitting pause break was the key!

 Thx, you saved my day. It was "Scroll Lock" for me. Hitting this again directly unlocked the Linux console.

This was the ticket for me as well, thanks!

Thanks, I own you a beer for day. In my case SCRLCK key

[Joelg316]

Thank you  and . It was the scroll lock key for me too.

You saved my day, . God bless you. It was Scroll Lock key in my case.

I have the same issue. My Linux VM console has been working fine and suddenly stopped taking any keyboard input. Either only taking a few keys or not taking any input. VMSA 6.7. Windows VM console works fine.

Anybody get this issue resolved?

Thanks,

Am i the only one who finds it weird that if i press any of the key: scroll lock, pause break, or any of the other keys is pressed the console doesn't respond anymore in vmware ???

My windows consoles doesn't have these issues and if i check my own laptop it also doesn't matter the state of these keys.

Is this a bug of something ? i am experiencing it at least in my ubuntu consoles, didn't experience it on my redhat consoles, but these are less used from the console
