I've tested the patchset successful with virsh command for both kvm and lxc vm.

Right now, libvirt only supports the cfq based blkio cgorup, this means if the block devices doesn't use cfq scheduler, the blkio cgroup will loss effect.
This patchset adds the throttle blkio cgroup support for libvirt, intoduces four elements for domain configuration and extend the virsh command blkiotune.

Oh, my hand slip. Thanks! BTW, chould you help to review or test this patchset? It runs well in my test box. Thanks. ------------------ Best regards! GuanQiang 12:46:48
