Hi, guys, I've developed some patches to support setting device iops and bps with blkio cgroup, by extending the existed 'domainSetBlkioParameters' and 'domainGetBlkioParameters' interface. Please help me to review the patches and give me your expertise. Thanks very much.

Beside device weight, read/write bps and iops throttle can be set per-device with these patches. Virsh command 'blkiotune' is extended to support the above function too.
