[lxc-users] lxc-start fails with "no systemd controller mountpoint found"

[F Dave]

Turns out that it was cgroup was mounted under /cgroup, so I was able to
create the folder there and mount it. However the container shows the same
error:

[root at devhost fs]# mount -t cgroup -o none,name=systemd cgroup
/cgroup/systemd/

[root at devhost fs]# grep cg /proc/mounts
cgroup /cgroup/cpuset cgroup rw,relatime,cpuset 0 0
cgroup /cgroup/cpu cgroup rw,relatime,cpu 0 0
cgroup /cgroup/cpuacct cgroup rw,relatime,cpuacct 0 0
cgroup /cgroup/memory cgroup rw,relatime,memory 0 0
cgroup /cgroup/devices cgroup rw,relatime,devices 0 0
cgroup /cgroup/freezer cgroup rw,relatime,freezer 0 0
cgroup /cgroup/net_cls cgroup rw,relatime,net_cls 0 0
cgroup /cgroup/blkio cgroup rw,relatime,blkio 0 0
cgroup /cgroup/systemd cgroup rw,relatime,name=systemd 0 0

[root at devhost fs]# lxc-start -F -n node2
