No if. the admin should be able to choose what backend to use, regardless
of the storage used, and probably of the dom0 OS (you have several backend
available in linux as well, isn't it) ?

Ho, that won't work anyway. The options to setup the network are different,

Then, as a compromise, could the default be specified in xend-config.sxp
and be overridable in the domU's config file ?
this way, the admin can set a sane defaut for his setup, and eventually
decide what to use on a per-domU basis.
