[Bug 1100843] Re: Live Migration Causes Performance Issues

@ccormier

I've thought all along it might be a libc issue but testing libc 2.13 on
precise would be rather difficult.  To some extent I feel like this
rules out the kernel as an issue though, since the same kernel on
precise/lucid yield different results.

Have you tried letting a precise VM idle without a livemigration to see
if performance degrades?  If not perhaps you could leave one idle over
the weekend and performance test on Monday?

I assume you're testing with qemu-kvm 1.0.0?  I've been testing with
qemu-kvm 1.2.0 as the performance is remarkably better for me.  This
would seem to indicate it's not qemu-kvm at fault either.
