Subject: [PATCH v10 14/21] KVM: selftests: Call TDX init when creating a new TDX vm
Date: Wed, 3 Sep 2025 23:54:44 -0700 [thread overview]
Message-ID: <20250904065453.639610-15-sagis@google.com> (raw)
In-Reply-To: <20250904065453.639610-1-sagis@google.com>
TDX VMs need to issue the KVM_TDX_INIT_VM ioctl after VM creation to
initialize the TD. This ioctl also sets the cpuids and attributes for
the VM.
