+This is intended to be used with OpenWrt project to provide image for use with
+QEMU ARM virt machine.

+Run with kvmtool
+
+	# start a named machine
+	lkvm run -k openwrt-armvirt-32-zImage -i openwrt-armvirt-32-rootfs.cpio --name armvirt0
+
+	# start with virtio-9p rootfs

+
+	# stop "armvirt0"

+
+	# stop all
+	lkvm stop --all
+
+The multi-platform ARMv8 target can be used with QEMU:
+
+	qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
+		-kernel openwrt-armvirt-64-Image-initramfs \
