Do you want to look at the pv-ops kernel (the long-term future), or the xen-linux kernel (a fork which will never make it as-is into Linux, but is ATM more widely used)? Stefano, which devices are enabled in qemu in our Xen tree? Can you give Anh some pointers on how to find out which files correspond to those devices?
