Public bug reported:
Hello.
Yesterday I've upgraded ubuntu 20.04 to 20.10 and I have soon realized
that libvirt stopped working with xen. Xen itself works ok for me,as u
can see :
root@ziomario-z390aoruspro:/etc/xen# xl list
Name ID Mem VCPUs State Time(s)
Domain-0 0 32065 16 r----- 435.8
but it does not with libvirt :
root@ziomario-z390aoruspro:/etc/xen# virsh pool-list --all
error: failed to connect to the hypervisor
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Connection
denied
this is what happens when I query for the status :
root@ziomario-z390aoruspro:/etc/xen# sudo systemctl status libvirtd.service

if xen works without libvirt AND it does not work with Libvirt,it is a bug of
libvirt. I dind't see this behavior with ubuntu 20.04 ; so it is a bug of
ubuntu 20.10. do u want to give a look ?
