If you used to think virtualization was complicated, think again...
Besides, did they release their whitepaper yet ?
"AMD SEV-SNP: Strengthening VM Isolation with Integrity Protection and More"

Not that I know.

So after that comes secure nested virtualization?

I'm already sweating...

Related to "Interrupt Protections": How is VMPL0 expected to actually perform the interrupt injection to VMPL3? (It cannot request from Hv as it is limited to only single vector) Doesn't it need a special CPU capability to do so? (INTn won't work either as we need a VMPL switch)
-
I also don't understand why "Interrupt Protection" is required. When Hv injects interrupt via V_IRQ / EVENTINJ, CPU should inject it only when RFLAGS.IF=1, V_TPR allows and no interrupt shadow. If these fields are protected by SEV-ES, how an unexpected interrupt is injected?
