Package: libvirt-bin
Version: 1.1.4-2
Severity:serious

When using virsh to start a domain with <cputune> tag like the following

  <cputune>
    <shares>4000</shares>
    <period>100000</period>
    <quota>-1</quota>
  </cputune>

It give me the following error :

error: Call to virDomainCreateWithFlags failed: Unable to read from 
'/sys/fs/cgroup/cpu/machine/VM-fe5f-KIWI.libvirt-qemu/vcpu0/cpu.cfs_period_us': 
No such file or directory

It seams that libvirt cannot create the required directory for the VM under 
/machine

this is my mount related to cgroup

cgroup_root on /sys/fs/cgroup type tmpfs (rw,relatime)

I'm using wheezy and have installed this version from the wheezy-backports.
