    Serial port locked after Win10 Pro VM/Service restart

    FrancoisFournier Lurker

      ESXi 6.7 on HP ProLiant DL380 G9 and Win10 Pro VM.

       

      Physical serial port assigned to VM and works fine under control of a service. It is assigned to device /dev/char/serial/uart0.

      Runs for days without a glitch.

       

      If I restart the VM or the service to update a piece of code or a configuration, the serial port is not available anymore, no matter how many times I do resets.

       

      To recover, I need to:

      - inhibit the serial port in the VM's Device Manager

      - restart the service

      - activate the serial port in the VM's Device Manager

      - restart the service again.

      - then it works ... until I need to restart the service another time ...

       

      Anyone has an idea what the cause may be ... and, most importantly, what's the solution?

       

      Thanks
