I checked and libvirt should complain if it is not mounted. But to be
sure, is it?
I do not know how to check it.
where the cgroupfs should be mounted to?
there are some cgroup directory infomation.
------------------
#ll /
.....
drwxr-xr-x. 3 root root 0 Jul 2 16:56 cgroup
....
# ls /cgroup
cgroup.procs cpu.cfs_period_us cpu.cfs_quata_us ....
------------------------
there are user and group is root root.
Is it because the libvirt donot have permission to operate the cgroup?
Thanks a lot.
