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

    wannavm Lurker

      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

            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..
