Hi there,
It's great that you're working on Xen. Sounds like you're making good
progress.
However, do you really have to use Xen 2.0.7? It's not really supported any
more - the 3.x series gets all the attention these days. The main difference
between the two from your point of view is probably in the control interface.
The Xend parts of the code are concerned with sending control messages to
domains in the right sequence so that their drivers may handshake and set up
shared memory / event channel. In Xen 3.x, the Xend components of a split
driver are very different and *much* simpler, but you need to use XenStore in
the devices.
Could you give any more detail about your device drivers? What requirements
do they have? (shared memory pages, event channels, other metadata etc...)
Cheers,
Mark
