Comment 4 for bug 1898871

Hi jchittum,
"Serial Port 1" is added with ubuntu-21.10-server-cloudimg-amd64.ova
The default configuration about "Serial Port 1" is
   Serial Port 1: Use physical serial port
   Status: Connected at PowerOn

But with the default configuration I get warning message as follows when power on the VM:
     Cannot connect the virtual device serial0 because no corresponding device is available on the host. Do you want to try to connect this virtual device every time you power on the virtual machine?

Workaround:
It can be fixed by Setting "Connected at PowerOn" to false.

Thanks
