domcreate_attach_vtpms shouldn't actually do anything unless you
requested a vtpm in the VM config, that you haven't done.

Is it possible that the error message is actually wrong?
I guess the error is just related to the creation of the vif somehow but
it is printed by domcreate_attach_vtpms because it is the first callback
being called.
