Hi,

you can try to use VDSM hook to add a dummy serial device to the VM domain XML. Or if you really need a physical device then you can use the hook to add the <hostdev> element to the domain XML. Don't forget to pin the VM to a specific host though.

Yes, pinning is most likely needed. As per libvirt configuration, there should be direct libvirt support, maybe predating hostdev:

Bests,
