We didn't see this exact problem BUT when runing OpenStack on a new platform we
hit problems in qemu, libvirt, greenthreads, eventlet, erlang and probably a
few others.

I think you need to (as Han's suggested) verify each step from "system booting" to OpenStack.

Look at each of the required components and verify that ther tests suits pass
for example does eventlet work on your system?

If a test fails then understand why.  You may not need to fix that specific
case if it's of no use to OpenStack "right now".

Good luck.

Yours Tony.
