How about: diag 308 subcode 0 and 1 require KVM and Ultravisor interaction, since the cpus have to be set into multiple reset states. * All cpus need to be stopped * The unshare all UVC needs to be executed * The perform reset UVC needs to be executed * The cpus need to be reset via the set cpu state UVC * The issuing cpu needs to set state 5 via set cpu state
