We had discussion on IRC about this today. This is an issue in libvirt 
rather than Xen. So I think a revert is not warrant here.
Instead, it was suggested to force push because it is going to take some 
times to fix libvirt (see more below).
Oleksandr already sent a patch to fix libvirt [1]. The problem is even 
if this is accepted, our testing branch for libvirt is 2 years behind 
because they switched to Meson and Osstest has not been adapted to the 
new build system.
Anthony kindly offered to update Osstest.

Regarding force pushing, I am waiting for the Osstest result to confirm 
that only the libvirt tests are failing in staging (we already have the 
results for smoke). So my plan is to force push on Monday.
Please let me know on Monday morning if you have some concerns with this 
approach.
Cheers,
