Yes, my fault, I copy-pasted the previous target type and then changed the wrong one.

The thing is that when you use spicevmc, the channel going through the guest (target -- frontend in the guest) is identified using the virtio channel name because it is virtio-serial-port. That's what you see in the XML. For the source (backend on host) there are only three spicevmc channel names to use: vdagent, smartcard and usbredir. We don't offer to choose that names since there is only one possible usage for each of those. OTOH with spiceport, you can choose the channel name yourself, have them as many as you want and since it provides _backend_ connection (source for the chardev), it is identified by this name in the _client_. From the technical POV, you can interconnect spiceport as a source with any other target that qemu supports. But that doesn't change the fact that spiceport is only used as a backend and is not seen in the guest. In the example I went with using isa-serial as a target, because that was the usage mentioned in the mail thanks to which I started working on it [1], but I to meet your needs you can go with: <channel type="spiceport"> <source channel="org.qemu.console.serial.0"/> <target type="virtio" name="whatever-name.you.want"/> </channel> which works with this patch too as it merely adds the backend to the mix. In this case it won't be serial port, but virtio-port (channel); that means you'll see '/dev/virtio-ports/whatever-name.you.want' in the guest instead of '/dev/ttyS0'. Martin P.S.: Due to spicevmc channel being implemented the way it is, it took me non-trivial amount of time to figure out how to expose this and I went through more "designs" before I figured this is just a backend, nothing else :) [1] http://lists.freedesktop.org/archives/spice-devel/2014-January/015919.html

Ah, I missed this was possible, hence the comments. It would probably be worth it to add a !isa-serial example either to the documentation or to the commit log. Thanks for the detailed explanation!

Yeah, had trouble wrapping my head around exposing spiceport when I gave it a quick look, good that you managed to get on top of it ;) Christophe
