for libvirt questions, I'd rather use <a class="moz-txt-link-abbreviated" href="mailto:libvirt-users@redhat.com" target="_blank" data-mce-href="mailto:libvirt-users@redhat.com">libvirt-users@redhat.com</a>, 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.
</pre></blockquote><pre>Indeed. Vdsm should notice that libvirtd has died, and restart itself.
However, it would be safer to stop Vdsm explicitly before you do that
