When trying to create a paravirtualized domU using virt-manager I get the following error
Traceback (most recent call last):

libvirt.libvirtError: An error occurred, but the cause is unknown
Does anyone know how to resolve this? I call virt-manager by entering "virt-manager" in terminal, the rest is done via the GUI. The environment is Ubuntu 20.04 and xen version 4.11.
'An error occurred, but the cause is unknown'
Anytime you see an error like that from libvirt it indicates an error reporting bug, so please report a bug with ubuntu.
The VM creation may be failing for legitimate reasons but it's tough to tell without libvirt reporting a good error
