Is it safe to let yum update these packages while the host has running VMs?
in maintenance mode? or not at all?
The safest way is to put a host into maintenance before updating.
All vms will be migrated to other hosts before the host is deactivated.
Some packages like sanlock cannot be updated while host is connected
to storage; trying to update them may kill sanlock, which will cause the
watchdog to reboot your host, killing your vms.
