I've also tested just upgrading cgmanager in VM/host only, and VM/host and container to wily levels (0.37) but that did not fix the issue in Vivid. > > 3 perhaps also set log_level=1 in /etc/libvirt/libvirtd.conf, restart > libvirt, > and show the journalctl -u libvirt-bin output. > We have this, but unfortunately to doesn't have anything useful w.r.t which calls in libvirt are failing. At best, we have syslog error when libvirtd attempts to write to cgroups on behalf of the VM and we get: Aug 18 20:18:59 openstack-single-ubuntu libvirtd[11203]: cgmanager: cgm_set for controller=devices, cgroup_path=machine/ubuntu-local-machine-1.libvirt-qemu failed: invalid request I'll collect this as well incase I missed something important.
