Re: [PATCH 0/3] Add complete blkiotune support for per-device with blkio cgroup

["hzguanqiang@xxxxxxxxxxxxxxxx" <hzguanqiang@xxxxxxxxxxxxxxxx>]

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.

The patches add a complete blkiotune support per-device with blkio cgroup

for both lxc or qemu driver, by extending the existed 'domainSetBlkioParameters'

and 'domainGetBlkioParameters' interface.

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.

  qemu: add blkiotune support for device iops and bps throttle setting

  lxc: add blkiotune support for per device

  blkiotune: add virsh support for blkiotune interface
