</span>Have you tried it with nova live-migration or only
with nova migrate?<br>
<br>
With nova live-migration it is possible to specify the
target host.<br>
<br>
usage: nova live-migration [--block-migrate]
[--disk-over-commit]<br>
<server> [<host>]<br>
<br>
Migrate running server to a new machine.<br>
<br>
Positional arguments:<br>
<server> Name or ID of server.<br>
<host> destination host name.<br>

<div>Initially I thought that the server group affinity
filter (available since Icehouse) would be suitable for
the use case you have outlined: - <a
moz-do-not-send="true"
href="http://docs.openstack.org/trunk/config-reference/content/section_compute-scheduler.html#servergroupaffinityfilter">http://docs.openstack.org/trunk/config-reference/content/section_compute-scheduler.html#servergroupaffinityfilter</a><br>
<br>
However it seems that it is currently only honoured at
boot and updated for the upcoming Kilo release - <a
moz-do-not-send="true"
href="https://blueprints.launchpad.net/nova/+spec/anti-affinity-on-migration">https://blueprints.launchpad.net/nova/+spec/anti-affinity-on-migration</a>.
Until then live migration may indeed be your only way to
achieve the required affinity behaviour.<br>
