Re: USB Audio Passthrough - Newbie Question
You appear to be on the right track.? Here is what my script looks like. emu-system-s390x? -display none -machine s390-ccw-virtio -m 2048M -cpu max,zpci=on,msa5-base=off -drive file=dasd/ubuntu.qcow2,format=qcow2 \ ?-net nic,model=virtio \ -vnc 127.0.0.1:4 \ ??? -net nic \ ??? -net user,id=user.0,hostfwd=tcp::5555-:22 & regards; Rahim ? ??
