Any consensus here? I double-checked the legacy xen driver and it does
in fact support <script> for <interface type='bridge'>. I'm not sure how
many users specify something other than the default, but I'm loath to
break them when moving from the old xen toolstack to libxl.

Marek,

Assuming we continue to allow <script> for type='bridge' interfaces in
the libxl driver, you'll have to change your patch to only allow it for
type 'bridge' and 'ethernet'.

BTW, sorry for the delay in getting to your patches. I have a bit of
time to work on libxl stuff and will get to reviewing them.

Regards,
Jim
