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..
