[libvirt] [PATCHv2 00/15] live block migration via virDomainBlockCopy

[Eric Blake]

v1 was here:
https://www.redhat.com/archives/libvir-list/2012-April/msg00068.html

changes from v1: Paolo has updated the qemu side of things, and built
a scratch image for RHEL that I was able to test with for the new
semantics.  I was actually able to successfully run two different
block copy jobs, one canceled and one pivoted, with SELinux disabled
and this patch series.

Patch 12/15 is for reference only when working with Paolo's build;
it will not go upstream.

Patches 13-15 are optional; the extra flexibility might be nice, but
I haven't yet played with those three enough to know if Paolo's build
behaves like I was expecting.

I obviously have more patches to write, such as supporting the REUSE_EXT
flag to reuse files instead of creating a new one, and fixing several
XXX comments related to SELinux, auditing, and disk locking.  But they
can be extra patches on top of this starting series.
