Hi Sebastian,

The commands are nearly identical - just replace quantum with nova!

Although, it sounds like you already have floating IPs being allocated
randomly.

That could be one of two things - either you have
auto_assign_floatingip=True in your configuration, or you misunderstand the
difference between fixed and floating ips.

When you boot an instance, does it get a private or public IP? And - when
you ran the network-create command, what IP range did you use?
