Hi,
I tried to run libvirt-1.0.2 with LXC as below, but it failed to mount cgroup.
You should change your cgroup configuration as below cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct,cpu) cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer) cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,nosuid,nodev,noexec,relatime,perf_event)
Libvirt lxc doesn't support configure cgroup as you did below now.
Why? IIRC old systems mount cgroup at /cgroup by default. This means libvirt lxc has backward compatibility on supporting cgroup?
YES Libvirt can successfully create cgroup for lxc doamin, the problem is we trying to mount cgroup in container and in special case we failed.
And, in the case can libvirt lxc give a user-friendly message to user about what user can do?
Yes, maybe this is the best solution.
