Problem :

We have also found that there is no "*cgroup*" directory created under * "/sys/fs/".* We have tried mounting the same manually using the below commands but we were not successful.
mkdir -p /dev/cgroup_cpuacct mount -t cgroup -o cpuacct cpuacct /dev/cgroup_cpuacct
(or)
mkdir -p /sys/fs/cgroup mount -t cgroup -o cgroup cgroup /sys/fs/cgroup
Please find the the domain info used for the creation of VM in the attachment. Please let us know, how to proceed futher.
Your inputs would be of great help to us.
Thanks and Regards, Shree Duth Awasthi.
