You can't terminate this with "ctrl-alt-]"? Works here. Can you make
sure your system really *has* output on the serial console by looking
at the /dev/pts/X yourself? You can find out the pty by looking at
/var/log/libvirt/qemu/<yourvm>.log - it should be the last second pty
listed. The first one is the monitor pty.
