# boot by runqemu:

# QB_SYSTEM_NAME: qemu name, e.g., "qemu-system-i386"

# QB_OPT_APPEND: options to append to qemu, e.g., "-show-cursor"
+#
# QB_DEFAULT_KERNEL: default kernel to boot, e.g., "bzImage"

# QB_MEM: memory, e.g., "-m 512"
+#
# QB_MACHINE: qemu machine, e.g., "-machine virt"
+#
# QB_CPU: qemu cpu, e.g., "-cpu qemu32"
+#
# QB_CPU_KVM: the similar to QB_CPU, but used when kvm, e.g., '-cpu kvm64',
# set it when support kvm.
+#
# QB_KERNEL_CMDLINE_APPEND: options to append to kernel's -append
# option, e.g., "console=ttyS0 console=tty"
+#
# QB_DTB: qemu dtb name
+#
# QB_AUDIO_DRV: qemu audio driver, e.g., "alsa", set it when support audio
+#
# QB_AUDIO_OPT: qemu audio option, e.g., "-soundhw ac97,es1370", used
# when QB_AUDIO_DRV is set.
+#
# QB_KERNEL_ROOT: kernel's root, e.g., /dev/vda
+#
+# QB_NETWORK_DEVICE: network device, e.g., "-device virtio-net-pci,netdev=net0,mac=@MAC@",
+# it needs work with QB_TAP_OPT and QB_SLIRP_OPT.
+# Note, runqemu will replace @MAC@ with a predefined mac, you can set
+# a custom one, but that may cause conflicts when multiple qemus are
+# running on the same host.

# QB_TAP_OPT: netowrk option for 'tap' mode, e.g.,
-# "-netdev tap,id=net0,ifname=@TAP@,script=no,downscript=no -device virtio-net-device,netdev=net0"
+# "-netdev tap,id=net0,ifname=@TAP@,script=no,downscript=no"
# Note, runqemu will replace "@TAP@" with the one which is used, such as tap0, tap1 ...
-# QB_SLIRP_OPT: network option for SLIRP mode, e.g.,
-# "-netdev user,id=net0 -device virtio-net-device,netdev=net0"
+#
+# QB_SLIRP_OPT: network option for SLIRP mode, e.g., -netdev user,id=net0"

# QB_ROOTFS_OPT: used as rootfs, e.g.,
# "-drive id=disk0,file=@ROOTFS@,if=none,format=raw -device virtio-blk-device,drive=disk0"
# Note, runqemu will replace "@ROOTFS@" with the one which is used, such as core-image-minimal-qemuarm64.ext4.

# QB_TCPSERIAL_OPT: tcp serial port option, e.g.,

# Note, runqemu will replace "@PORT@" with the port number which is used.
