For AMD SEV-ES and SEV-SNP, handling this exception is crucial for functionality.

This is not covered on the online docs?

@Zildj1an so I see this documented at: https://docs.rs/x86_64/latest/x86_64/structures/idt/struct.InterruptDescriptorTable.html#structfield.vmm_communication_exception

There's also an enum value defined here: https://docs.rs/x86_64/latest/x86_64/structures/idt/enum.ExceptionVector.html#variant.VmmCommunication

Were you expecting to find it documented somewhere else?
