Hi,

This small series implements the "spiceport" channel type.

libvirt supports "spiceport" since version 1.2.2.

The Spice WebDAV channel allows the client to share a folder with the
guest. There is some default configuration to use the "spiceport" type
appropriately.

(once the guest VM is configured with a WebDAV channel, a small
service can be used in the guest to expose a webdav server, that can
be mounted, see also
http://cgit.freedesktop.org/spice/spice/tree/docs/manual/manual.txt
"Folder Sharing")

Thanks, I've pushed this.

I'm a bit confused though, I understand the virtio-serial channel name maps to
/dev/.../<name> in the VM, but what exactly does the source channel map to?


Target is '/dev/virtio-serial/<name>', in this case the name is
'/dev/virtio-serial/org.spice-space.webdav.0' IIRC and on the source
this is a text channel in the spice protocol which the client
connected might use.  The same way when you do:

<serial type='spiceport'>
 <source channel='org.spice.spicy'/>
 <target type='isa-serial' port='0'/>
</serial>

this will get you a connection from the spice client ('org.spice.spicy'
text channel) to the guest (/dev/ttyS0 or similar depending on the udev
implementation).
