The HVMOP_set_evtchn_upcall_vector hypercall sets the per-vCPU upcall vector, to be delivered to the local APIC just like an MSI (with an EOI). This takes precedence over the system-wide delivery method set by the HVMOP_set_param hypercall with HVM_PARAM_CALLBACK_IRQ. It's used by Windows and Xen (PV shim) guests but normally not by Linux.
