[libvirt] [PATCHv2 0/3] 'autodeflate' attribute for mememory balloon

[Dmitry Andreev]

This patch-set adds support for the new feature 'deflate-on-oom'
that has been added to the QEMU virtio memory balloon a month ago.
This feature lets a guest OS deflate balloon on OOM.

With 'deflate-on-oom' enabled virtio balloon will release
it's memory if possible right before an OOM termination of
processes.

QEMU commit with the complete feature description:
http://git.qemu.org/?p=qemu.git;a=commit;h=e3816255bf4b6377bb405331e2ee0dc14d841b80

v2:
 * attribute renamed to 'autodeflate' [1/3][3/3]
 * capability check added [2/3][2/3]
 * ability to change 'autodeflate' for running domain wasn't added
   because QEMU doesn't allow to on/off 'deflate-on-oom' in runtime
 * more tests added [3/3]
