[libvirt] [PATCH 00/13] libxl: add basic support for migration

[Jim Fehlig]

Based on an earlier patch from Chunyan Liu

https://www.redhat.com/archives/libvir-list/2013-September/msg00667.html

This patch series adds basic migration support to the libxl driver.
Follow-up patches can improve pre-migration checks and add support for
additional migration flags.

Patches 1-12 are almost exclusively code motion, moving functions from
the main driver module into the libxl_domain and libxl_conf modules.

Patch13 is rather large and provides the migration implementation.  If it
is preferred to split patch13 further, I'm open to suggestions on ways to
do that.

I've done some basic migration testing of this series using NFS shared
storage.  Error handling only minimally tested though.  I attempted a
migration to host with a different bridge than the source, verifying
the migration failed and the vm was resumed on the source.
