[libvirt] [PATCH] qemu: fix virtual serial/parallel ports via unix/tcp

Hi, as to my understanding we should pass 'server' instead of 'listen' to forward virtual serial ports via unix domain sockets or tcp. See: http://bellard.org/qemu/qemu-doc.html I also added nowait to tcp,unix and telnet since otherwise qemu/kvm would wait for a connection before proceeding which breaks vm startup. I wonder why nowait wasn't added with: 0138ff79f26a5fdaae9b13d6345a84817a144e06 though. Possible patch attached. -- Guido
