would that stop any of the running VMs ?
it shouldn't, but if you have ovirt engine running, make sure that power management not active for this host, since after timeout (usually 1 minute) when vdsm is down, the host will be fenced (restarted) - then the vms will surely stop.. look at http://www.ovirt.org/Automatic_Fencing for more info about automatic fencing in engine.

Hi,
I believe it's save, but just wanted to re-check, is it save to restart

Hi,
for libvirt questions, I'd rather use libvirt-users@redhat.com , but for
this particular one, I can confirm that libvirt is written in a way that
enables it to be restarted without any impact on the machines which are
being ran.
Of course I can't say "nothing will happen" due to the fact that every
single time something can happen, but nothing _should_ happen to any of
your machines.
Indeed. Vdsm should notice that libvirtd has died, and restart itself.
However, it would be safer to stop Vdsm explicitly before you do that
(for example http://gerrit.ovirt.org/8283 )
