[Xen-devel] Re: a xen question

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

Ahn, the backends and frontends depends on which version of the kernel
you're using.  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?  Thanks!
