so..it was not in Maintenance when you run the update?
You should avoid doing that as an update to any package may interfere with
running guests. E.g. a qemu rpm update can (and likely will) simply kill all
your VMs, I suppose similarly for Gluster before updating anything the volumes
should be in some kind of maintenance mode as well

Perhaps libvirtd restarted because of those updates, which causes a vdsm
restart as well, dropping the host connection temporarily
