So, summarizing your suggested XML syntax, it more or less looked
like this:
<graphics type='rdp' port='12345' listen='172.21.4.3' autoport='no'
headless='yes' reuseConnection='yes'
allowMultiConnections='yes'
auth='external' authtimeout='1234'/>
Historically with Xen and QEMU there has only been ability to have either
SDL graphics, or VNC graphics, but not both.
With VirtualBox you can actually have the local desktop window *and*
RDP at the same time, or just the local desktop, or just RDP, or
neither. There seems to be a SDL graphics mode too, but the docs says
that's only really for developers, and it doesn't look to be exposed
in the API
This really says to me that we should represent the virtualbox graphics
configuration with 2 separate <graphics> tags, one for the local
desktop display config, and one for the RDP config.
<graphics type='desktop'/>
<graphics type='rdp' port='1234' autoport='no' listen='172.21.4.3'/>
If RDP is not enabled, then don't include the 2nd. If the local desktop
display is not enabled, then don't include the 1st. This avoids the
the 'headless' attribute being exposed in the XML directly. I chose
type='desktop' as representing the 'native' desktop app display of the
virt technology in question. I imagine it'll take similar attributes
to the type=sdl, while the type=rdp would be similar to type=vnc.
For the allowMultiConnection & reuseSingleConnection attributes, I think
i'd prefer something a little less verbose as the XML attribute names.
How about
multiUser='yes|no' (for allowMultiConnection)
replaceUser='yes|no' (for reuseSingleConnection)
For the local desktop window, is there any way in the API to indicate
what X display it should be shown on ? Obviously if launched within a
desktop session it'll display on that session. If I ssh into a remote
machine though, currently virtualbox libvirt driver will start the
display on the $DISPLAY from the forwarded SSH session virsh is running
in which isn't really what I wanted. I think we really need to be able
to indicate a desired X $DISPLAY (or equiv) in the XML for the local
desktop window graphics mode, eg, akin to the current SDL config we
could have
<graphics type='desktop' display=':0.0'/>

Daniel
