Managing virtual networks

You can access details about a virtual network by going to Networking > Virtual Networks in the Ignite management console, and then selecting the virtual network for which you want to view details. The resulting Overview page contains detailed information about the selected virtual network. This includes information about the virtual network's auto-deployed services (DHCP and NAT), the network services application, and the firewall profile (if any).

  4. After adding, changing, or removing a static binding from an instance that already has a DHCP IP, the DHCP server and client will still have the old lease cached, so additional steps are required:
    1. Open a console to the NFV instance.
      1. Run vi /var/lib/dnsmasq/dnsmasq.leases and type i to edit the file.
      2. Remove the line containing the old IP of the instance whose static binding is being changed. Enter ESC and :wq to save the changes.
      3. Run systemctl restart dnsmasq
    2. Open a console to the instance whose static binding is being changed
      1. For Linux instances: run rm /var/lib/NetworkManager/dhclient-*-<InterfaceName>.lease to remove the old DHCP lease file, and nmcli con up <Interface Name> to bring up the interface.
      2. For Windows instances: Open Network and Sharing Center and click Change adapter settings. Select the network adapter and click Disable this network device, then click Enable this network device

Editing virtual network routing service
