This target is for use with the qemu, qemu-aarch64, qemu-armv7l
|
|
devices. It generates an executable :file:`run.sh` which
|
|
invokes QEMU. It connects the Liminix
|
|
serial console and the `QEMU monitor <https://www.qemu.org/docs/master/system/monitor.html>`_
|
|
to stdin/stdout. Use ^P (not ^A) to switch between monitor and
|
|
stdio.
|
|
|
|
If you call :command:`run.sh` with ``--background
|
|
/path/to/some/directory`` as the first parameter, it will
|
|
fork into the background and open Unix sockets in that
|
|
directory for console and monitor. Use :command:`nix-shell
|
|
--run connect-vm` to connect to either of these sockets, and
|
|
^O to disconnect.
|
|
|
|
Liminix VMs are networked using QEMU socket networking. The
|
|
default behaviour is to connect
|
|
|
|
* multicast 230.0.0.1:1234 ("access") to eth0
|
|
* multicast 230.0.0.1:1235 ("lan") to eth1
|
|
|
|
Refer to :ref:`border-network-gateway` for details of how to
|
|
start an emulated upstream on the "access" network that
|
|
your Liminix device can talk to.
