kvm/x86: return meaningful value from KVM_SIGNAL_MSI If kvm_apic_map_get_dest_lapic() finds a disabled LAPIC, it will return with bitmap==0 and (*r == -1) will be returned to userspace. QEMU may then record "KVM: injection failed, MSI lost (Operation not permitted)" in its log, which is quite puzzling.
