Thanks heaps for including the traceback in your message, it makes
these things much easier to debug.

This looks to me like a permissions problem. The code has tried to
make a directory on your NFS share, and that has failed. Specifically,
this looks like the directory the instance files go into.

What happens if you try to create a directory on the NFS share as the
user that nova is running as?

Cheers,
Michael
