It is anything but proof. Kernel inclusions are often a matter of
convenience.

Why are you so determined to use Asterisk in a VM? You're asking for
trouble. Asterisk belongs on dedicated hardware.

We're just trying to help -- but if you insist on running Asterisk in a

That's not a risk I'd want to take.
