Subject: [PATCH v2 06/18] whpx: i386: make nested virtualisation init failure non-fatal
Date: Tue, 27 Oct 2026 16:57:25 +0100	[thread overview]
Message-ID: <20261027155737.59271-7-mohamed@unpredictable.fr> (raw)
In-Reply-To: <20261027155737.59271-1-mohamed@unpredictable.fr>

On some CPUs too old for Windows 11 (Skylake) support but running
it anyway, WHP advertises nested virt despite it
being unavailable.

As such, make failures to initialise nested virt even when advertised
non-fatal.
