Thanks Daniel,

When I run

sudo xl create -c vtpmmgr-stubdom.cfg

I receive the following error:

How I can solve this problem?

This is fixed by a hypervisor patch in xen-unstable:


That patch has not yet been applied to the 4.3 tree, however you can apply
it yourself. I'm adding Jan to CC as a ping to backport this patch; a
report on if the patch fixes the issue may also be helpful here.

A ping means that you previously asked for this to be backported,
but I don't think you ever did. Considering that your first try at
fixing this was broken, I would also not have considered this as a
candidate on my own (in fear of further issues)...

Yes, looking back I should have explicitly requested the backport after
it was committed to unstable and tested. Thanks for applying the patch
now that it has been confirmed to work.
