Thanks for the tip. I need to wait (might be a few weeks) to see when it
starts eating swap again, then I'll do what you suggest. I got the
system from 94% swap in use to 39% by restarting some of the VMs, then I
was able to swapoff/swapon to empty the swapfile.

Here's a snapshot of the system in an idle state, sr is mostly above 300
