Well, (a) today you can't really externally retry a single instance build without just creating a new one. The new one could suffer the same fate, but that's why we just did the auto-disable feature for nova-compute. Thing (b) is that if we fix rebuild so it works on a failed shell-of-an-instance from a boot operation, we could easily exclude the host it failed on, but it'd require some additional logic. --Dan _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
