You don't really want to use PTYs to connect 2 VMs together. Instead try using one of the TCP or UDP connection methods http://libvirt.org/formatdomain.html#elementsCharTCP eg, configure one VM with <serial type="tcp"> <source mode="bind" host="127.0.0.1" service="2445"/> <protocol type="raw"/> </serial> and the other with <serial type="tcp"> <source mode="connect" host="127.0.0.1" service="2445"/> <protocol type="raw"/> </serial> Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
