Looks OK to me, but I think we should document these (including that they're experimental and future syntax for enabling RME will change) in the "TCG VCPU Features" section of docs/system/arm/cpu-features.rst. We could mention in the commit message here why we're making them experimental x- properties too. thanks -- PMM
