Subject: [PATCH 08/15] x86/kconfig/64: Enable the KVM host in the defconfig
Date: Tue,  6 May 2025 19:09:17 +0200	[thread overview]
Message-ID: <20250506170924.3513161-9-mingo@kernel.org> (raw)
In-Reply-To: <20250506170924.3513161-1-mingo@kernel.org>

These days all distros enable KVM, and since the x86 defconfig
aims to be a distro kernel work-alike with fewer drivers and
a shorter build time, enable the KVM host in the defconfig too.
