Question

How do I add or remove an IP address to/from a VE?

Answer

• For Host-routed mode

To add the IP address 192.168.1.2 to VE 101, run the following command on the Hardware Node:

# vzctl set 101 --ipadd 192.168.1.2 --save 

To release an IP address from a VE, use the same command with the --ipdel option.

• For Bridged mode

First create a new veth virtual network adapter and assigns the name to the Ethernet interface inside the Container:

# vzctl set 101 --netif_add eth0 --save 

After this, to add the IP address 192.168.1.2 to VE 101 in bridged mode, run the following command on the Hardware Node:

# vzctl set 101 --ifname eth0 --network Bridged --ipadd 192.168.1.2/24 --gw 192.168.1.1 

To remove the bridged adapter from container, use --netif_del option.

Note

Valid network mask and gateway settings are required in case of Bridged mode.
