3270 devices
|
||
|
|
============
|
||
|
|
|
||
|
|
QEMU supports connecting an external 3270 terminal emulator (such as
|
||
|
|
``x3270``) to make a single 3270 device available to a guest. Note that this
|
||
|
|
supports basic features only.
|
||
|
|
|
||
|
|
To provide a 3270 device to a guest, create a ``x-terminal3270`` linked to
|
||
|
|
a ``tn3270`` chardev. The guest will see a 3270 channel device. In order
|
||
|
|
to actually be able to use it, attach the ``x3270`` emulator to the chardev.
|
||
|
|
|
||
|
|
Example configuration
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
* Add a ``tn3270`` chardev and a ``x-terminal3270`` to the QEMU command line::
|
||
|
|
|
||
|
|
-chardev socket,id=char_0,host=0.0.0.0,port=2300,nowait,server,tn3270
|
||
|
|
-device x-terminal3270,chardev=char_0,devno=fe.0.000a,id=terminal_0
|
||
|
|
|
||
|
|
* Start the guest. In the guest, use ``chccwdev -e 0.0.000a`` to enable
|
||
|
|
the device.
|
||
|
|
|
||
|
|
* On the host, start the ``x3270`` emulator::
|
||
|
|
|
||
|
|
x3270 <host>:2300
|
||
|
|
|
||
|
|
* In the guest, locate the 3270 device node under ``/dev/3270/`` (say,
|
||
|
|
``tty1``) and start a getty on it::
|
||
|
|
|
||
|
|
systemctl start serial-getty@3270-tty1.service
|
||
|
|
|
||
|
|
This should get you an addtional tty for logging into the guest.
