Comment 10 for bug 1957924

As outlined upstream in the linked issue:

"Libvirt queries the qemu monitor instead of debugfs if available to fetch the stats." since 6353e8f5c1f8336a58c2fde93c1c17de224a4dfb which is in v8.7.0 and later and therefore in Ubuntu lunar and later.

Combined with the qemu fix that was done in Lunar this should be good on both.
