Hi Eric, Yes, I restarted libvirtd after mounting the blkio controller. I have libvirt 0.9.10 running on my machine. I'm using CentOS 6.3 (64 bit) virsh # version Compiled against library: libvir 0.9.10 Using library: libvir 0.9.10 Using API: LXC 0.9.10 Running hypervisor: LXC 2.6.32 On Wed, Mar 20, 2013 at 3:27 AM, Eric Blake <eblake@redhat.com> wrote:

Hi all,
I want to limit the I/O bandwidth inside the container, so I used virsh command blkiotune. But when I enter a command:
virsh # blkiotune lxcguest --weight 250
I get following errors:
error: Unable to change blkio parameters error: Requested operation is not valid: blkio cgroup isn't mounted
I also have blkio cgroup mounted. What can be the problem?
Have you restarted libvirtd since you mounted the blkio cgroup? Which version of libvirt are you running, on what platform?
