Sorry but this fix breaks ssh-connections for everyone not using a sh- based shell as login-shell. I personally use tcsh as login shell and nc -q 21 | grep -q 'requires an argument';if [ $? -eq 0 ] ; then CMD='-q 0';else CMD='';fi; isn't valid csh line. ** Attachment added: log http://launchpadlibrarian.net/51510325/log -- remotely executed netcat (nc) uses -q option which is not universally supported https://bugs.launchpad.net/bugs/517478 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Libvirt should use similar hack like in virt-manager (from previous RedHat's bugzilla report): we pass a shell script as the SSH command, and try to detect these incompatibilities. It's definitely a hack, but we don't have a lot of options: http://hg.fedorahosted.org/hg/virt-manager/rev/1f781890ea4a -- remotely executed netcat (nc) uses -q option which is not universally supported https://bugs.launchpad.net/bugs/517478 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

You can fix it temporarily by installing a version of nc which recognizes the -q option on the remote server. You can try my workaround.
