Hi Feng,
I need run the below steps with libvirt-1.0.3.
$ mkdir /cgroup
$ mount -t tmpfs cgroup /cgroup
$ mkdir /cgroup/{freezer,devices,memory,cpuacct,cpuset}
$ mount -t cgroup -ofreezer cgroup /cgroup/freezer
$ mount -t cgroup -odevices cgroup /cgroup/devices
$ mount -t cgroup -omemory cgroup /cgroup/memory
$ mount -t cgroup -ocpuacct cgroup /cgroup/cpuacct
$ mount -t cgroup -ocpuset cgroup /cgroup/cpuset
What's the new to mount cgroup with libvirt-1.0.4?
Best Regards,
Olivia
