Re: hmm

If you don't directly control the hardware and what software is running on it you are lying to yourself it is secure.

You forgot the troll icon. As anybody haunting Reg for any length of time is well aware, there is no such thing as "secure". Rather, there is a whole spectrum of being more or less trouble (ie money, skill, and risk to life and limb) to breach your security. On that spectrum, guest memory encryption with cryptographically-sound key management is a very useful point. It won't stand up to a determined and resourceful state-level attacker - nothing would - but it does protect you from an electronic equivalent of a casual smash'n'grab, while still allowing you to rent somebody else's hardware.

For many uses, that's plenty secure enough.
