  23 Run with kvmtool
  24
  25         # start a named machine
  26         lkvm run -k openwrt-armvirt-32-zImage -i openwrt-armvirt-32-rootfs.cpio --name armvirt0
  27
  28         # start with virtio-9p rootfs
  29         lkvm run -k openwrt-armvirt-32-zImage -d root-armvirt/
  30
  31         # stop "armvirt0"
  32         lkvm stop --name armvirt0
  33
  34         # stop all
  35         lkvm stop --all

  37 The multi-platform ARMv8 target can be used with QEMU:
  38
  39         qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
  40                 -kernel openwrt-armvirt-64-Image-initramfs \
