Synopsis: Can't boot on hypervisor that only supports grant table v1

State-Changed-From-To: open->closed
State-Changed-By: jdolecek%NetBSD.org@localhost
State-Changed-When: Mon, 24 Jan 2022 01:24:48 +0000
State-Changed-Why:
This won't be chnaged, v2 is required.
Since the grant system is central to proper memory management, it's
extremely bad idea to maintain compatibility with the legacy v1 interface,
which would only be used in extremely rare cases.
AFAIK v2 can be turned off in Dom0 for DomUs, ask them to allow v2.
