Hi,
libvirt 2.3 added a couple of new perf metrics:
https://libvirt.org/git/?p=libvirt.git;a=commit;h=bae660869de0612bee2a740083fb494c27e3f80c
After some consultation with FChE, the types below are believed to
be correct, considering also:
https://bugzilla.redhat.com/show_bug.cgi?id=1381714
It would be of course nice if someone with access to a system
supporting all these events / metrics would be able to confirm.
