That's using QEMU directly though, right? Because the default for libvirt is to use isa-serial and you would have to tell it explicitly to use pci-serial instead, with <serial type='pty'> <target type='pci-serial' port='0'/> </serial> My point is that you or Christoffer having configured your QEMU binary differently shouldn't be enough to affect the command line generated by libvirt. -- Andrea Bolognani / Red Hat / Virtualization -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
