I cannot create the lxc container. It used to work a few days later on this system, though.
When I do sudo lxc-create -n abc -t ubuntu
, the container's creation process seems to finish successfully (no error code thrown on exit).
But when I try to start it:
sudo lxc-start -n abc
lxc: call to cgmanager_move_pid_abs_sync(blkio) failed: invalid request
lxc-start: Could not find writable mount point for cgroup hierarchy 11 while trying to create cgroup.
lxc-start: Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/blkio/grp_1
lxc-start: Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/cpu/sys_daemon
lxc-start: Device or resource busy - cgroup_rmdir: failed to delete /sys/fs/cgroup/cpuset/
lxc-start: failed creating cgroups
lxc-start: failed to spawn 'abc'
The problem fails the same way on both trusty
and saucy
templates.
Is it a grounds to file a bug against Ubuntu?
I use Ubuntu Trusty 14.04
