I was envisioning the tag being set by the end user to say "please keep my VM running until I say otherwise", or something like "auto-recover" for short. So, it's specified by the end user, but potentially acted upon by the system (as you say below). > Of course, one might implement some external polling/monitoring system > using server instance tags, which might do a nova list --tag $TAG --host > $FAILING_HOST, and initiate a migrate for each returned server instance... Yeah, that's what I was thinking. Whatever system you use to react to a failing host could use the tag as part of the criteria to figure out which instances to evacuate and which to leave as dead. -- Russell Bryant _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
