I've used something simliar in my local.conf[1] w/ today's git. I get a
successfull install too[2]. However, booting an instance is just
perpetually stuck in SCHEDULING state:
$ nova list

I don't see anything interesting in Scheduler/CPU logs:

Examining my install log[2], I only see 3 ERRORs that looked legitimate:
