README 

This is intended to be used with LEDE project to provide image for use with
QEMU arm-softmmu virt machine.

Run with qemu-system-arm

	# boot with initramfs embedded in
	qemu-system-arm -nographic -M virt -m 64 -kernel lede-armvirt-zImage-initramfs

	# boot with accel=kvm
	qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel lede-armvirt-zImage-initramfs

	# boot with a separate rootfs
	qemu-system-arm -nographic -M virt -m 64 -kernel lede-armvirt-zImage \
	  -drive file=lede-armvirt-root.ext4,format=raw,if=virtio -append 'root=/dev/vda rootwait'

	# boot with local dir as rootfs
	qemu-system-arm -nographic -M virt -m 64 -kernel lede-armvirt-zImage \
	  -fsdev local,id=rootdev,path=root-armvirt/,security_model=none \
	  -device virtio-9p-pci,fsdev=rootdev,mount_tag=/dev/root \
	  -append 'rootflags=trans=virtio,version=9p2000.L,cache=loose rootfstype=9p'

Run with kvmtool

	# start a named machine
	lkvm run -k lede-armvirt-zImage -i lede-armvirt-rootfs.cpio --name armvirt0

	# start with virtio-9p rootfs
	lkvm run -k lede-armvirt-zImage -d root-armvirt/

	# stop "armvirt0"
	lkvm stop --name armvirt0

	# stop all
	lkvm stop --all
