Robot: Automated text replacement (-VE +container)
Vitual network device (<code>venet</code>) is the default network device for a [[VEcontainer]]. This network device looks like a peer-to-peer connection between [[VEcontainer]] and the [[CT0|host system]]. It does packet switching based on IP header. This is a default network device for VE container (an alternative is [[veth]] device).
Venet device is created automatically on [[VEcontainer]] start. Vzctl scripts set up an appropriate IP address and other settings on venet inside a VEcontainer.
== Usage ==
You might want to check /etc/init.d/vz script to make sure the module gets loaded during startup.
=== Adding IP address to a VE container ===
<pre>
vzctl set <CTID> --ipadd <IP1>[,<IP2>,...] [--save]
vzctl set 101 --ipadd 10.0.0.1 --save
</pre>
After executing this command IP address 10.0.0.1 will be added to VE container 101 and IP configuration will be saved to a VE container configuration file.
=== Removing IP address from a VE container ===
<pre>
vzctl set <CTID> --ipdel <IP1>[,<IP2>,...] [--save]
vzctl set 101 --ipdel 10.0.0.1
</pre>
After executing this command IP address 10.0.0.1 will be removed from VE container 101, but IP configuration will not be changed in VE container config file. And after VE container reboot IP address 10.0.0.1 will be assigned to this VE container again.
