Re: [libvirt] [PATCH 0/6 v3] Add blkio cgroup support
Hi Gui,
thanks for your reply.
Actually, this two series doesn't care how blkio cgroup works.
They just provide
the ability to put Guest into given cgroup and tune the tunables.
Currently, You can only control the "blkio.weight" tunable. For examle, If
you'd
like to give more I/O bandwidth to a given Guest, you can assign a bigger value
to "blkio.weight" by running blkiotune command.
Okay, so then basically, if I understand the current state of the blkio
controller correctly (see my original message), this is useless at this
point.
I don't mean to offend you in any case, I just wondered how you used (or
intended to use) this, since I myself did not yet find a good way to
actually limit a guests I/O hunger.
Regards
Dominik
