* Problem:
It's not possible to start kvm guest. There's always an error:
"ERROR    Unable to deny all devices for XXXXXX: No such file or directory"

* Ways to reproduce:

1) Try to import guest:
======================CUT============================
root at catlap:/etc/libvirt# virt-install --name test2 --ram 300 --disk path=/home/marek/development/libvirt_tests/deb1.img --import

Starting install...
Guest installation complete... restarting guest.
Unable to deny all devices for test2: No such file or directory
Domain installation may not have been
 successful.  If it was, you can restart your domain
 by running 'virsh start test2'; otherwise, please
 restart your installation.
ERROR    Unable to deny all devices for test2: No such file or directory
Traceback (most recent call last):
  File "/usr/bin/virt-install", line 780, in <module>
    main()
  File "/usr/bin/virt-install", line 698, in main
    dom.create()
  File "/usr/lib/python2.6/dist-packages/libvirt.py", line 293, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: Unable to deny all devices for test2: No such file or directory
======================/CUT============================

Import OK, but starting guest failed.

Then...
2) Try to start guest with debug enabled

======================/CUT============================

In this tread guy was able to overcome the problem by uninstalling cgroup-bin and libpam-cgroup:

... but I don't have such packages installed on my system.
