[Xen-devel] [PATCH v3 00/27] Libxl migration v2



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.  Please test!
