Chun Yan Liu was working on a patch to implement migration in the libvirt libxl driver, but she wasn't able to finish tidying the patch before departing on maternity leave. She recently returned to work and I'd expect a refreshed patch soon - after working through her backlog. But why is libvirt integration listed as a Xen 4.3 feature? AFAIK, all of this work is in libvirt and really doesn't have much to do with the release of 4.3. Cheers, Jim
