Same thing happened with us with running ubuntu precise kvm for our hypervisors. VMs that are live-migrated suffer noticeable performance degradation. We tried a few performance tests against live-migrated vs non-migrated VMs and the problem is easily reproducible.. (we used jmeter)

Ubuntu (hypervisor): 12.04.1 LTS
libvirt:0.9.8-2ubuntu17.4
qemu-kvm:1.0+noroms-0ubuntu14.3
storage: NFS exports.

Guest OS: Ubuntu 12.04.1 & RHEL 5.5
