getCPUStats of a domain by a non-root user - libvirtError: Requested operation is not valid: cgroup CPUACCT controller is not mounted
Hello,
I'm trying to use libvirt as a non-root user to obtain statistics on the
CPU usage by VMs using the Python API. I'm performing basically the
following steps:
import libvirt
conn = libvirt.openReadOnly(None)
dom = conn.lookupByUUIDString('268e38ea-1bc7-41e4-c19e-8eff682e58e4')
dom.getCPUStats(True, 0)
However, they result in the following error:
libvir: QEMU Driver error : Requested operation is not valid: cgroup
CPUACCT controller is not mounted

i guess if?virConnect.create was
