I'm doing this all the time using USB-to-serial-cables and minicom
instances in a Standalone HVM.

It would probably work just by assigning that USB device to a regular AppVM,
but since I also have other devices connected (ICE, I2C/SPI logger,
logic analyzer) I just assign the entire USB controller to the HVM.

If your serial port controller shows up with qvm-pci you could also try
to assign that one the the VM.
