Once you get back to using just USB passthrough it's helpful to dump
out the entire domain XML, ie:
sudo virsh dumpxml the_guest
Also the full qemu command line. Look for a file called
/var/log/libvirt/qemu/the_guest.log or $HOME/.cache/libvirt/qemu/log/the_guest.log.
In both cases send the complete XML and complete command line to the
list.

Hi Rich,
Included below is the information requested. The command-line options are
not typical of a VM generated using virt-manager since I am running VFIO
with VGA passthrough, so I had to customize the QEMU arguments a bit as well
as use Q35 machine type.
