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.
