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?
