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
Is the cgroupfs mounted?
I checked and libvirt should complain if it is not mounted. But to be sure, is it? I do not know how to check it. where the cgroupfs should be mounted to?
there are some cgroup directory infomation. ------------------ #ll / ..... drwxr-xr-x. 3 root root 0 Jul 2 16:56 cgroup .... # ls /cgroup cgroup.procs cpu.cfs_period_us cpu.cfs_quata_us .... ------------------------ there are user and group is root root. Is it because the libvirt donot have permission to operate the cgroup? Thanks a lot. xuejie chen.
