Hi,<br>
<br>
At last weeks nova meeting it was decided that the "initial patch to
simply extend multi-boot to schedule with hint". This has been
implemented by the following <a
href="https://review.openstack.org/#/c/21070/" target="_blank">https://review.openstack.org/#<wbr>/c/21070/</a>
<br>
<br>
This patch does the following:<br>
1. It introduces two scheduling hints:<br>
i. group_name - the name of a scheduling group<br>
ii. group_policy - the group scheduling policy. At the moment
anti-affinity is supported. In the future we plan to add network
proximity.<br>
2. In order to be able to treat addition of new VM's to the
scheduling policy the group_name and group_policy are stored in the
database as metadata (hopefully at the summit we will be able to
discuss this in more detail to see how they can become first class
citizens).<br>
<br>
In order to be able to achieve better performance and availability
it would be best to do the entire group deployment in one shot (this
is what was implemented in <a
href="https://review.openstack.org/#/c/19906/" target="_blank">https://review.openstack.org/#<wbr>/c/19906/</a>)<br>
<br>
Any input and comments will be great.<br>
Thanks<br>
Gary<br>
