On the subject of VNC server, the element currently just contains <graphics type='vnc'/> Now the (undocumented) assumption is that the VNC server is listening on a port number 5900+<domain id>. eg, Domain 3 listens on port 5903. This may be fine for dev / testing purposes, but this is not really a acceptable assumption to make long term. Xen could quite easily change to allocate arbitrary ports to each domain on a first-come, first-serve basis. When libVirt is ported to QEMU, there will be no correlation between domain ID and vnc port number. Thus I'd suggest we extend the XML for VNC thus: <graphics type='vnc'> <listen port="5903"/> </graphics> XenD doesn't currently give us the port number in the SEXPR it returns so we'll have to have code to explicitly insert a suitable <listen/> tag manually, but its well worth it, avoiding need to hardcode port number assumptions in application code. On a similar theme, Xen provides a serial console for each guest domain. Curently people access it with 'xm console <blah>', however, the actual console is just a psuedo TTY, so if one knows the /dev/pts/<N> path there is no need to use 'xm console' at all. Thus I think we could have another TODO item, to add '<serial port="/dev/pts/3"/>' element to the <devices> section of the XML.
