[Openstack] Database (Got timeout reading communication packets)

This is a 3 node Galera cluster on 3 KVM virtual machines. The errors are
constantly printing in the logs, and no node is excluded from receiving the
errors. I don't know whether they had always been there or not, but I
noticed them after an update.

The openstack services operate normally, the dashboard is fairly slow, but it
always has been.

The hosts are all networked with bonded 10G SFP+ cables networked via a
switch. Pings between the VMs seem fine. If I were to guess, any networking
problem would be between the guest and host due to libvirt. Anything that I
should be looking for there?
