Hm, when I use that, I get
lxc-start 20170508163649.375 INFO lxc_cgroup -
cgroups/cgroup.c:cgroup_init:68 - cgroup driver cgroupfs-ng initing for t1
lxc-start 20170508163649.375 DEBUG lxc_cgfsng -
cgroups/cgfsng.c:filter_and_set_cpus:452 - Path:
/sys/devices/system/cpu/isolated to read isolated cpus from does not exist.
which still stops the container from starting, but is different from your error.
