Hi Wolfgang,

Yes, currently Nova only allows associating security groups at boot, though
you can change the rules in a security group post boot.

Quantum (new openstack networking service) will be adding a more advanced
notion of security groups which allows changing groups of booted instances
and other improvements.  This had been targeted for Folsom-3, but looks
very unlikely to make it in time for Folsom.

The difference between Nova security groups and Quantum security groups is
similar to the differences between traditional amazone security groups and
Amazon "VPC" security groups (see: http://aws.amazon.com/vpc/faqs/#S2)
