I'm now complaining :)
The bind_interdomain() trick is needed for the ioreq events channel:
when it gets installed, it is supposed to be between the HVM domain and
dom0 (the stub domain doesn't exist anyway). The meaning of the test is
hence to allow the stub domain to hijack that event channel (because it
has privileges on the remote domain).
With that fix, stub domains are working again (but Cirrus bios doesn't
work yet)
