Hi Anthony,

/var/log/libvirt/libvirtd.log is empty, there is no log.

these are the processes that are running related to xen

ubuntu@arm64:~$ ps -aux | grep xen

and libvirtd is also running fine

ubuntu@arm64:~$ ps -aux | grep libvirt
root      3182  0.7  0.0 196772 16300 ?        Sl   12:13   0:00

--color=auto libvirt

is there anything I am missing?

Thanks
