Re: [Xen-devel] question on the evtchan stuff

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

Yes, pretty much. I/O will require you to implement virtual drivers
based on interdomain communications (i.e., shared memory + inter-domin
event channels). You could perhaps get some mileage out of the Linux
drivers though (also, using those will allow you to track changes in
the API as we move towards a 2.0 release of Xen).
