I think you are referring to the instance group api extension. https://wiki.openstack.org/wiki/InstanceGroupApiExtension
As far as I know, this extension is not supported in jclouds right now. If it helps, the extensions supported for nova in master are here: https://github.com/jclouds/jclouds/tree/master/apis/openstack-nova/src/main/java/org/jclouds/openstack/nova/v2_0/extensions ________________________________________ From: Martin Eppel (meppel) <mep...@cisco.com> Sent: Wednesday, July 29, 2015 7:26 PM To: user@jclouds.apache.org Subject: openstack affinity / antiaffinity in jcouds Hi, I had a question if jclouds currently supports the affinity / anti-affinity concept (and more specifically for openstack) where VMs get deployed either co-located on the same compute host or not. In openstack, affinity / anti-affinity is supported through server-groups, does jcloud support any of the following (openstack specific) nova commands : server-group-create Create a new server group with the specified server-group-delete Delete specific server group(s). server-group-get Get a specific server group. server-group-list Print a list of all server groups. Secondly, does it support the option in the nova boot command to apply the affinity / anti-affinity configuration, for example: nova boot --image "image1" --hint group=<group-UUID> ...... If there is a documentation which spells out the support please point me to it Thanks Martin Eppel
