While preparing my talk for DevConf, where I want to present this awesome tool
I've found couple of bugs in it.

New subject: [libvirt] [PATCH 1/2] virt-host-validate: Check those CGroups that we actually use
Since the introduction of virt-host-validate tool the set of
cgroup controllers we use has changed so the tool is checking for
some cgroups that we don't need (e.g. net_cls, although I doubt
we have ever used that one) and is not checking for those we
actually use (e.g. cpuset).

New subject: [libvirt] [PATCH 2/2] virt-host-validate: Fix error level for user namespace check
From the code it seems to me that we need user namespace iff
configured in domain XML. Otherwise we don't use it at all.
However our tool is more strict about that. Fix this discrepancy.

This is fun. The leading ">" is an artifact of escaping, to prevent
(poorly written?) MUAs from mistaking a line starting with "From" in
the body for the From: header.
You would think 'git format-patch', and most importantly 'git am',
would be clever enough to take this into account, but alas they
don't and just pass the commit message through.
s/iff/if/
Not a typo: "iff" is shortand for "if and only if", and by doing a
quick search in the git log you'll find that there are quite a few
previous instances. Mostly introduced by Michal :)
Cheers.
