[Pkg-libvirt-maintainers] Bug#721979: libvirt-bin: At least one cgroup controller is required: No such device or address

[Laurent Bigonville]

Package: libvirt-bin
Version: 1.1.2-1
Severity: important

Hi,

When trying to start a domain (kvm) in virt-manager, I'm getting the
following error/backtrace:

Erreur lors du démarrage du domaine: At least one cgroup controller is required: No such device or address

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 117, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1160, in startup
    self._backend.create()
  File "/usr/lib/python2.7/dist-packages/libvirt.py", line 697, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: At least one cgroup controller is required: No such device or address


I'm not running systemd on this machine, but systemd-logind is running
and cgroups are mounted:

bigon at soldur:~$ cat /proc/mounts |grep cgroup
none /sys/fs/cgroup tmpfs rw,rootcontext=system_u:object_r:sysfs_t:s0,seclabel,relatime,size=4k,mode=755 0 0
systemd /sys/fs/cgroup/systemd cgroup rw,nosuid,nodev,noexec,relatime,name=systemd 0 0

When unmounting /sys/fs/cgroup/systemd the domain is able to start.

Cheers

Laurent Bigonville
