Here is an small guide to test this for the ones that want to check it
faster:
Add a spiceport to a virtual machine adding this under devices in the XML
<channel type='spiceport'>
<source channel='org.freedesktop.FleetCommander.0'/>
<target type='virtio' name='org.freedesktop.FleetCommander.0'/>
<address type='virtio-serial' controller='0' bus='0' port='2'/>
</channel>
Boot machine, Connect to it as usual using spice-html5 and as root:
echo "CHILI" > /dev/virtio-ports/org.freedesktop.FleetCommander.0
In the browser console yo sould see the events for opening the port, the
message and the port closing.
If in a week or so there is no other feedback then I will contact you
Jeremy.
Thanks and cheers!
