By Mouhamadou Diaw<\/strong><\/p>\n

In a previous blog <\/a>, I was talking about virtual machines on ODA servers. Sometimes it comes that we want to add another network interface for other purpose.
\nIn this blog I am describing the main tasks to add a second network interface card on KVM virtual machine. Let\u2019s describe the context
\nI have an ODA X8-2M with appliance 19.12. This ODA contains virtual machines for the applications. The virtual machine only has one NIC used for the public connexion. The idea is to add a second network interface that will be used for the backups
\n-The oda server : oda-dev-01
\n-The virtual machine : vmserver_appli
\nWe show the actual network configuration for the virtual machine vmserver-appli. Only eth0 is present in the VM.<\/p>\n

As we can see below the eth0 is actually using the vNetwork pubnet of the physical ODA server. The pubnet is configured with the btbond1.<\/p>\n

So the idea is to create backupnet vNetwork based on btbond2. Later the backupnet vNetwork will be attached to the virtual machine.The command odacli create-vnetwork is used to create backupnet<\/p>\n

To add a second network interface, let\u2019s attach the backupnet vNetwork to the VM . Just note the use both \u2013live and \u2013config
\n–live: The change is applied to the running VM instance, but does not persist after the VM stops.
\n–config: The change persists in the configuration of VM instance and takes effect on subsequent reboots.<\/p>\n

Now you can configure this second network card according to your needs<\/p>\n

Conclusion<\/h3>\n

Hope this blog will help. Just a recommendation is to always restart VMs with odacli stop-vm<\/em> after modifications, this will validate that your changes are persistent or not<\/p>\n","protected":false},"excerpt":{"rendered":"
