Re: [Users] Unable to run VM with "Unable to create cgroup" error message

Hi, the only problem I could imagine is that there is really some directory missing, but you said it is there. Fromt his point I see two things you can try: 1) run libvirt with debugging output enabled [1] 2) try to create the directories manually Hopefully it'll give us more information on what's wrong.
