If the exit flag of SIE indicates that a machine check has happened during guest's running and needs to be injected, inject it to the guest accordingly. But some machine checks, e.g. Channel Report Pending (CRW), refer to host conditions only (the guest's channel devices are not managed by the kernel directly) and are therefore not injected into the guest. External Damage (ED) is also not reinjected into the guest because ETR conditions are gone in Linux and STP conditions are not enabled in the guest, and ED contains only these 8 ETR and STP conditions. In general, instruction-processing damage, system recovery, storage error, service-processor damage and channel subsystem damage will be reinjected into the guest, and the remain (System damage, timing-facility damage, warning, ED and CRW) will be handled on the host.
