I allways get to the third attempt and get rejected. That's because the qemu+ssh URI has an inherent design limitation that it can only validate a single connection, but migration requires two connections. You can try qemu+libssh:// URIs instead, which is supposed to resolve the authentication issues by using libssh within virsh instead of an external call to ssh(1) (although I haven't tried it myself). Or you can set up passwordless login over ssh (such as by using ssh-copy-id) - but remember that you must set it up so that root can access user@IP_ADDRESS:PORT (since 'sudo virsh' is running as root, not you). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
