Subject: [PATCH v8 08/10] KVM: selftests: Force GUEST_MEMFD flag for SNP VM type
Date: Wed, 5 Mar 2025 16:59:58 -0600	[thread overview]
Message-ID: <20250305230000.231025-9-prsampat@amd.com> (raw)
In-Reply-To: <20250305230000.231025-1-prsampat@amd.com>

Force the SEV-SNP VM type to set the KVM_MEM_GUEST_MEMFD flag for the
creation of private memslots.
