Working (boot from volume). One thing which is missing is image preparation. it needs to be addressed manualy (https://github.com/ceph/ceph-openstack-tools), or dirty coded within libvirt/connection.py :-) -- Tomasz Paszkowski SS7, Asterisk, SAN, Datacenter, Cloud Computing +48500166299 _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
