These often suggests that your xencommons initscript is not up to date and
isn't populating some of the required nodes for dom0. I'm not sure if this
would have the knock on effect of the breakage you describe, but it is
worth fixing in any case.

Given "No such file or directory" I'd also be inclined to check that
/etc/xen/scripts exists and has stuff in it, especially vif-* and that they
are executable, there #! refers to a shell which exists etc.

Weirdly our automated test test doesn't seem to include the stubdom jobs
for 4.5 (they appear to being at 4.6), but I can't see at all where such a
test is deliberately suppressed by the test code. Perhaps Wei (CC'd) knows.

FWIW the flights testing stbudom in xen-unstable use a cfg file which looks
like:

It doesn't look to me to be materially very different to what you have.
