[libvirt] [PATCHv3 00/16] live block migration via virDomainBlockCopy

v1 was here: https://www.redhat.com/archives/libvir-list/2012-April/msg00068.html v2 was here: https://www.redhat.com/archives/libvir-list/2012-April/msg00222.html changes from v2: added patch 12/16, addressed some review comments and made minor changes from more of my own testing CAVEAT: Paolo and I had an IRC conversation, where we decided that 'drive-mirror' might do better to take a mandatory 'full':'bool' (or an even more powerful optional '*base':'str') argument for determining how much to stream (full vs. shallow, or even the backing file of the copy as matching the base argument of 'block_stream') rather than overloading the 'mode':'no-backing-file' as the only way to get a full pull. If that change goes in qemu, then we will need a v4, to tweak how the 'drive-mirror' monitor command is called, and take advantage of the additional flexibility it offers. 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 13/16 is for reference only when working with Paolo's build; it will not go upstream. Patches 14-16 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.
