An SEV-ES guest does not allow register state to be altered once it has been measured. When an SEV-ES guest issues a reboot command, Qemu will reset the vCPU state and resume the guest. This will cause failures under SEV-ES. Prevent that from occuring by introducing an arch-specific callback that returns a boolean indicating whether vCPUs are resettable.
