Hello!
On Friday I migrated some of your VMs to a new virt host, labvirt1015. Early today that host suffered a hardware failure, crashed, and was down for quite some time.
No data was lost; your VMs have been migrated to a new host (labvirt1017) and are either back up already or will be back up and running in a few hours. Each was halted and rebooted abruptly, though, so you might want to have a look and make sure they're acting as you'd expect.

Sorry for the downtime!
