[Users] failed nestd vm only with spice and not vnc

[Gianluca Cecchi]

I replicated the problem with same environment but attached to iSCSI
storage domain.
So the Gluster part is not involved.
As soon as I run once a VM on the host the VM goes into paused state
and in host messages:


Feb  5 19:22:45 localhost kernel: [16851.192234] cgroup: libvirtd
(1460) created nested cgroup for controller "memory" which has
incomplete hierarchy support. Nested cgroups may change behavior in
the future.

And in qemu.log for the VM:
