I'm not sure what to make of this, but looking at /var/log/messages on all 3 of the hosts,it appears that the kernel disabled my oVirt networks at the same exact time on all 3 hosts. This occurred twice this morning, once around 8am and again around 8:30am:
ovirtmgmt is the storage network.
Private is the frond-end network.
I actually don't have *any* backup storage domains currently, and no backups to
speak of, so that wouldn't have been a cause from this morning.
My goal for this week is to install a 4th physical server with some spinning
disks, and expose those as an NFS mount point so that I can build a backup
domain.
I also hope to get the 10Gbps network cards installed on the remaining two
hosts, to get 10Gbps connectivity up and running between all 3 of the HCI hosts.
