VMmanager: Administrator guide

Assigning IP addresses with OS tools

The article contains instructions on how to manually add an IP address to servers with different operating systems.

To add an IP address, you will need to edit the network interfaces file. You can do this using standard OS editors. For example, in the Linux OS family, you can use the vi, nano, etc.

Example command to edit /etc/network/interfaces
vi /etc/network/interfaces

IPv6 settings

To add an IPv6 address, you will need information about the network parameters. This information is available in the VM card: go to Virtual Machines → click on the VM name → IP addresses tab → IPv6 tab → Network parameters button.
