From 126190379c57b7947dc7af278bee848cb3976e10 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 22 Feb 2024 16:42:48 -0800 Subject: [PATCH] KVM: selftests: Extend VM creation's @shape to allow control of VM subtype Carve out space in the @shape passed to the various VM creation helpers to allow using the shape to control the subtype of VM, e.g. to identify x86's SEV VMs (which are "regular" VMs as far as KVM is concerned).
