Virtual network device
Vitual network device (venet) is the default network device for VE. This network device looks like a ppp connection between VE and host system. It does packet switching based on IP header.
venet is created automatically on VE start. vzctl scripts setup appropriate IP and settings on venet inside VPS.

Virtual network device usage
Adding IP address to a VE
vzctl set <VEID> --ipadd <IP1>[,<IP2>,...] [--save]
|
Note: This option is incremental, so IP addresses are added to already existing ones. |
Example
vzctl set 101 --ipadd 10.0.0.1 --save
After executing this command IP address 10.0.0.1 will be added to VE 101 and IP configuration will be saved to a VE configuration file.
Removing IP address from a VE
vzctl set <VEID> --ipdel <IP1>[,<IP2>,...] [--save] vzctl set <VEID> --ipdel all [--save]
Example
vzctl set 101 --ipadd 10.0.0.1
After executing this command IP address 10.0.0.1 will be removed from VE 101, but IP configuration will not be changed in VE config file. And after VE reboot IP address 10.0.0.1 will be assigned to this VE again.
