Sounds like dynamic save state utilizing the HDD, is what I'm reading, I don't like the mention of Games VM not having full direct access to the hardware though, that's more overhead compared to the 360 unless they optimized it to the point where it's more efficient, but I doubt it as I think they are just trying to provide a friendly dev environment for the studios like what they did with Windows on PC.

I can't see that happening utilizing the HDD with fast switch between both... have to be memory.

They don't have to cache all the APP VM content in RAM, they just need the basic services like UI and current layout and cache the rest on the HDD. Game VM would obviousy use more, but it's supposed to anyways so it's fine to cache all the Games VM in RAM.

You don't have to cache anything.  The VMs are both in memory.  You simply suspend the VM. 

I honestly believe the HyperVisor OS has the actual UI, with the apps running in the Apps VM and the games running in the Games VM.
