Not sure if it's relevant but cgroup.service failed at boot time:

[martin@ps-1866 ~]$ systemctl status cgconfig.service
cgconfig.service - LSB: start and stop the WLM configuration
          Loaded: loaded (/etc/rc.d/init.d/cgconfig)

An update (libguestfs?) solved this issue. Please close this report.

I'm getting again the error:

libvirtError: Unable to create cgroup for $VIRTIMAGE: No such file or

Checking the logs I see:

May 19 13:38:30 piernb libvirtd: 13:38:30.440: 1643: error : qemuSetupCgroup:199 : Unable to create cgroup for $VIRTIMAGE: No such file or directory

May 19 13:38:30 piernb libvirtd: 13:38:30.452: 1643: warning : qemudShutdownVMDaemon:3115 : Failed to remove cgroup for $VIRTIMAGE

I was able to solve it by modifying the configuration in the file /etc/libvirt/qemu.conf:

 cgroup_controllers = [ ]

I'm using the latest F15, with the testing repo enabled.

I am also experiencing this error in a fresh install of Fedora 15.
Comment 7 darrell pfeifer 2011-05-25 19:02:46 EDT
Same "unable to create cgroup" problem for me. Using updated rawhide.
Comment 8 Heath Petty 2011-05-26 14:08:46 EDT
I hit this on Fedora 15 GA. I (re)started cgconfig, then restarted libvirtd and I was able to start my VMs again. It looks like cgconfig is crashing. I didn't see an abrt alert, so I didn't catch the crash.

Comment 9 darrell pfeifer 2011-05-26 22:39:22 EDT
The works with the latest rawhide (so with systemd 28-1)

Restarting cgconfig fixes it here too, it was also in a failed state here.
Comment 13 Ian Pilcher 2011-06-11 16:07:51 EDT
Does anyone know what is actually causing these errors?  Perhaps more
importantly, does anyone care?

Restarting libvirtd is a fairly painful workaround, particularly when one
hits the error while creating a new VM (since everything has to be

This is a systemd bug already being tracked. Closing as DUPLICATE
