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

Run with qemu-system-arm

# boot with initramfs embedded in
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage-initramfs

# boot with accel=kvm
qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
openwrt-armvirt-32-zImage-initramfs

# boot with a separate rootfs
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage \
-drive file=openwrt-armvirt-32-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 openwrt-armvirt-32-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 openwrt-armvirt-32-zImage -i openwrt-armvirt-32-rootfs.cpio --name armvirt0

# start with virtio-9p rootfs
lkvm run -k openwrt-armvirt-32-zImage -d root-armvirt/

# stop "armvirt0"
lkvm stop --name 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 \
