getCPUStats of a domain by a non-root user - libvirtError: Requested operation is not valid: cgroup CPUACCT controller is not mounted
...Requested operation is not valid: cgroup CPUACCT controller
is not mounted
However, CPUACCT is actually started and mounted to /mnt/cgroups/cpuacct,
and the following steps actually work for the root user:
import libvirt
conn = libvirt.open(None)
dom = conn.lookupByUUIDString('e06c6b11-d655-5a98-fd90-724d106066f9')
dom.getCPUStats(True, 0)
Output:
[{'cpu_time': 10245430984L,
'system_time': 5350000000L,
'user_time': 1870000000L}]
The domains referenced above are started for the non-root and root users
respectively.
I would be very grateful for any pointe...
