Re: [libvirt-users] Errors while using blkiotune command
Saurabh, please make sure blkio controller has
been mounted on your host firstly then need to
restart libvirtd service after manually mounting
it.
# lssubsys
cpuset
cpu
cpuacct
memory
devices
freezer
net_cls
blkio
or
# grep blkio /proc/mounts
cgroup /cgroup/blkio cgroup rw,relatime,blkio 0 0

Subject: [libvirt-users] Errors while using blkiotune command
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?
Thanks in advance.
Regards,
Saurabh Deochake
