Ok, part of the problem seemed to be that the documentation assumed I set the 
password guest for the rabbit guest account. Did that now and the problem 
changed:

root at controller:~# nova network-create vmnet --fixed-range-v4=10.0.0.0/24   --
bridge-interface=br100 --multi-host=T
ERROR: The server has either erred or is incapable of performing the requested 
operation. (HTTP 500) (Request-ID: req-900a80bd-dfc1-49fc-9599-239fd5b9b7e3)

nova-api.log shows:
