Ouch.  I think this broke with the move of OpenVZ kernel stuff to
modules.  The modules are only loaded when the "vz" service starts, and
only if you already have at least one OpenVZ container.  So when you
create the very first container on a system, the modules are not yet
loaded.  I am not sure how and whether to correct this best.

Maybe provide an extra invocation mode for service "vz", which "vzctl
create" would use?  Sounds hackish to me.

Maybe have the modules loaded in all cases, even if the system is not
going to host any OpenVZ containers?  Sounds untidy to me.

Despite of these errors, what would happen if you simply start the "vz"
service at this point?  I guess everything would work just fine.

Sure, but please see above re: the exception (no containers configured
on service startup).

Thank you for reporting this!
