Subject: [PATCH] hw/arm/virt: Default enable the virtualization option(VHE) on A64FX
Date: Fri, 14 Jan 2022 16:24:37 +0900	[thread overview]
Message-ID: <20220114072438.3085054-1-ishii.shuuichir@fujitsu.com> (raw)

At A64FX specification, VHE is enabled by default, so
the virtualization option should be enabled when -cpu a64fx
is specified.
