Hi Alex,
I checked it again and found that blkio controller is already mounted.
Output of above commands are also same.
Saurabh,
Please check whether libvirt container is mounted in the blkio cgroup controller.
(/cgroup/blkio/libvirt/), and if not the libvirt dameon has to be restarted, if it is
available check for the respective domain is available in the respective container,
(/cgroup/blkio/libvirt/qemu/<domain-name>), if not the respective domain also has to
be
restarted to get the cgroups reflected.
I hope this helps.

So the problem still persists.
