If the plan to get key xen drivers into 2.6.38 succeeds
With the caveat that I don't really know what I'm looking for, I didn't see these make 2.6.38-rc1 (plenty of other Xen work, though). I saw a proposed patch for netback hit xen-devel yesterday.
There was talk of userland netback and blkback in xen 4.1 which use the gntdev interface which did make it into 2.6.38 (userland blkback apparently gives the similar performance as the kernel one, netback is not as good). I am not sure of the details though, nor how you might use them if they are available.
Xen folks worked to give QEMU a userland netback/blkback implementation, but I don't believe this functionality is integrated into the mgmt stack at this time, so likely not much use yet.
userspace blkback is included in xen-unstable (4.1) !
Afaik xen-unstable automatically 'falls back' to userspace blkback if kernel blkback is not available.
I'm not sure if xen-unstable also has userspace netback..
