I have only tried on Ubuntu 15.04 using SandyBridge CPU features.  I
actually have Haswell CPUs in the host servers, but the TSX issue is
preventing me from using that CPU feature set. (Would love to see that
fix come downstream!)

Live migration does not work.  Suspend does work.

Issue exists in both 1.2.12-0ubuntu12 and 1.2.12-0ubuntu13.
