This series adds support for the libxl migration v2 stream, and untangles the existing layering violations of the toolstack and qemu records.
It can be found on the branch "libxl-migv2-v3" git://xenbits.xen.org/people/andrewcoop/xen.git http://xenbits.xen.org/git-http/people/andrewcoop/xen.git No major changes over v2, but a lot of minor changes following review. At the end of the series, legacy migration is no longer used. The Remus code is untested by me. All other combinations of suspend/migrate/resume have been tested with PV and HVM guests (qemu-trad and qemu-upstream), including 32 -> 64 bit migration (which was the underlying bug causing us to write migration v2 in the first place). Anyway, thoughts/comments welcome.
