Subject: [PATCH 1/4] mshv: Add nested virtualization creation flag
Date: Wed, 18 Feb 2026 14:47:59 +0000 [thread overview]
Message-ID: <20260218144802.1962513-1-anbelski@linux.microsoft.com> (raw)
From: Muminul Islam <muislam@microsoft.com>
Introduce HV_PARTITION_CREATION_FLAG_NESTED_VIRTUALIZATION_CAPABLE to
indicate support for nested virtualization during partition creation.
This enables clearer configuration and capability checks for nested
virtualization scenarios.
