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) Dan On Wed, Aug 8, 2012 at 4:32 AM, Wolfgang Hennerbichler < [email protected]> wrote: > it's not me :) > http://forums.openstack.org/**viewtopic.php?f=10&t=719<http://forums.openstack.org/viewtopic.php?f=10&t=719> > > > On 08/08/2012 11:06 AM, Wolfgang Hennerbichler wrote: > >> hi, >> >> is it me or is it openstack who can't modify security groups for running >> virtual machines? >> nova help | grep sec >> doesn't give me a clue. >> >> thanks for a hint, >> Wolfgang >> >> > > -- > DI (FH) Wolfgang Hennerbichler > Software Development > Unit Advanced Computing Technologies > RISC Software GmbH > A company of the Johannes Kepler University Linz > > IT-Center > Softwarepark 35 > 4232 Hagenberg > Austria > > Phone: +43 7236 3343 245 > Fax: +43 7236 3343 250 > wolfgang.hennerbichler@risc-**software.at<[email protected]> > http://www.risc-software.at > > ______________________________**_________________ > Mailing list: > https://launchpad.net/~**openstack<https://launchpad.net/~openstack> > Post to : [email protected] > Unsubscribe : > https://launchpad.net/~**openstack<https://launchpad.net/~openstack> > More help : > https://help.launchpad.net/**ListHelp<https://help.launchpad.net/ListHelp> > -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Dan Wendlandt Nicira, Inc: www.nicira.com twitter: danwendlandt ~~~~~~~~~~~~~~~~~~~~~~~~~~~
