Subject: [PATCH v3 00/27] Libxl migration v2
Date: Mon, 13 Jul 2015 13:01:19 +0100 [thread overview]
Message-ID: <1436788907-1921-1-git-send-email-andrew.cooper3@citrix.com> (raw)
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!
~Andrew
