= Exporting devices through devnodes =
You can export devices from the Hardware Node (HN) to the container (CT) by using the devnodes flag, here for example for a serial port adaptor:
<pre>
$ vzctl set 1024 --devnodes ttyUSB0:rw --save
</pre>
<pre>
# vzctl enter 1024
entered into CT 1024
root@1024 / [1]# screen /dev/ttyUSB0 57600 8N1
[detached from 17017.pts-0.1024]
root@1024 / [2]# ls -al /dev/ttyUSB0
crw-r----- 1 root root 188, 0 Apr 17 15:36 /dev/ttyUSB0
</pre>
If you remove suddenly the device, vzctl will complain and continue:
<pre>
# vzctl enter 1024
Incorrect device name /dev/ttyUSB0: No such file or directory
Invalid value for DEVNODES=ttyUSB0:rw, skipped
entered into CT 1024
root@1024 / [1]#
</pre>
= List of successfull exported devices =
* /dev/ttyUSB0
