[libvirt] [PATCH 1/2] conf: Allow virtio scsi to using unit 16383

In qemu, 16383 is the top valid value for virtio scsi unit number: $ /usr/libexec/qemu-kvm \ -device \ virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x6 \ -drive \ file=A.qcow2,format=qcow2,if=none,id=drive -device \ scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=16383,drive=drive,id=disk VNC server running on ::1:5900 $ /usr/libexec/qemu-kvm \ -device \ virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x6 \ -drive \ file=A.qcow2,format=qcow2,if=none,id=drive -device \ scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=16384,drive=drive,id=disk qemu-kvm: ...: bad scsi device lun: 16384 So adjust libvirt to use the virtio scsi unit valid range 0..16383.
