I am having a few hosts running just libvirt, among which I can do live
migration. Is there some way or does someone have a script to balance
guests evenly across these hosts? Based on memory usage eg.
So, look at the general server logs. Try and start the qemu command from
the command line, enable verbose logging, increase logging etc etc.
