Subject: [PATCH v15 03/20] KVM: SEV: Select KVM_GENERIC_PRIVATE_MEM when CONFIG_KVM_AMD_SEV=y
Date: Wed, 1 May 2024 03:51:53 -0500 [thread overview]
Message-ID: <20240501085210.2213060-4-michael.roth@amd.com> (raw)
In-Reply-To: <20240501085210.2213060-1-michael.roth@amd.com>
SEV-SNP relies on private memory support to run guests, so make sure to
enable that support via the CONFIG_KVM_GENERIC_PRIVATE_MEM config
option.
