Hi,
one of the seems to fail on our build system, vircgrouptest fails with

The test runs fine locally.

libvirt: error : this function is not supported by the connection driver: host
cpu counting not supported on this node
Interesting. This error is produced becasue there's no
/sys/devices/system/cpu/cpu0 directory on your system. Therefore:
1) it's our bug that in testsuite we access real data from host's sysfs.
We need a bit more mocking.
2) it's interesting that you don't have cpu0. Can you please share dir
listing of /sys/devices/system/cpu?
