And it is a difficult balance to strike... providing the full v* feature set would have a massive cost. My user community is looking for an on-ramp to cloud. They agree it is the right way to go in the longer term but it has to be a journey, not a 'leap from the lion's head' moment. This has a set of steps from their current service consolidation environment towards a full cloud model. I would find this discussion with my users much easier if we can offer basic VM restart/live migration along the way. > -jay > > > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev@lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
