i the past (before migrating to google apps) i did:

# cat /proc/1/cgroup
1:blkio,net_cls,freezer,devices,memory,cpuacct,cpu,ns,cpuset:/

if you see anything after the ":/" (the cgroup name), you're in a
cgroup; if you see nothing, your on the host.

worked fine for me, but i don't know if it's 100% reliable.
