[Bug 1100843] Re: Live Migration Causes Performance Issues

[Mark Petersen]

I tested with qemu-kvm 1.3.0.  It seems that the issue still exists, but
that it exists without a live migration if you wait long enough.

That is if you start a VM on one node and run phoronix batch-run
pts/compilation, wait 4 hours (with the VM and physical host doing
nothing else) an re-run the test you'll get results on the VM similar to
if you run the test and then live migrate to a new host.  I have no idea
what's causing this behavior, but it seems to be reproducible.

For now this can probably be closed.  I'll resubmit a new bug (possibly
upsteam) if I can figure out how to get more details to help properly
diagnose how/when/why the VM's slow down over time.
