I don't really much like this as an idea, although our new data streaming APIs would make it fairly easy to add. For somes types of pool, virt-manager could in fact do cloning between machines / connections, without needing API support. eg, if using an iSCSI pool, a SCSI FibreChannel, a NFS / GFS / GlusterFS pool these are all shared storage mechanism. virt-manager ought to be able to work out that pool X on one connection, is the same as pool Y on the second connection, and thus just do the clone completely within pool X and just refresh pool Y to see the new volume. If the source pool is tied to the local machine (eg local disk, LVM, non-network FS), then it could go via a second networked pool that is shared. Ultimately I think that if someone has more than a handful of hosts running virtualization, then it is very likely that they have got networked/multi-host-accessible storage of some kind which would allow for cross-connection cloning without this being needed in libvirt API directly Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
