Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

When I run the command:

nova network-create vmnet --fixed-range-v4=
--bridge-interface=br100 --multi-host=T

I get the error:

 ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-f981271e-deae-4cb5-b118-d20d6301a295)

What am I doing wrong?
