Subject: [RFC PATCH v2 06/11] hw/ppc: Restrict KVM to various PPC machines
Date: Fri, 19 Feb 2021 18:38:42 +0100	[thread overview]
Message-ID: <20210219173847.2054123-7-philmd@redhat.com> (raw)
In-Reply-To: <20210219173847.2054123-1-philmd@redhat.com>

Restrit KVM to the following PPC machines:
- 40p
- bamboo
- g3beige
- mac99
- mpc8544ds
- ppce500
- pseries
- sam460ex
- virtex-ml507

Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com>

RFC: I'm surprise by this list, but this is the result of
     auditing calls to kvm_enabled() checks.
