How to create a new VM network and VNIC on Oracle VM ?

OVM networking featured

Oracle VM for x86 has many network functions unlike traditional servers.  In Oracle VM each physical network link will be called as network port. These network ports will be used for oracle VM server management , live migration, Cluster heartbeat , ISCSI storage and virtual machines network. If you use the same network ports for all these functions , we will face network performance issues. So we need to divide these functions and distribute the work loads to different network ports to balance the load. Here we will see how we can create a dedicated network for virtual machines and how to create a virtual NICS using that network .

1.Login to oracle VM manager console.Navigate to Hardware – >  Resources – > Network.You can see that there is no work is available for Virtual machine .

Oracle VM Networking Tab

2.Click on “+” to add new network .

3.Select the network use from that given list .Here i am just selecting virtual machine.

Enter the network name and purpose of the network

4.Select the server which are going to use this network.

Select the servers for the network

5.Select the available ports(physical network interface) per server . Here i have selected the port2 from both the servers.

Selecting available Ethernet ports for network

If you are not sure what port2 and port3 is using in the back-end of OVS servers, Just select the oracle VM server and click on Ethernet tab.You can see that eth1 is mapped to port2 and eth2 is mapped to port3.

Mapping port names to eth names

6.No need to configure any IP address from virtual machine network. Just select “None”.

7.Once the new virtual machine network is created, you can see status like below.

Network created for VM’s

We have successfully created  the virtual machine’s  dedicated network ports. These ports can’t be used directly on virtual machines. You need to have VNIC in an order to present it .

How to create a virtual NIC on oracle VM ?

1.Once you have created the network for virtual machine , you need to create VNIC to assign to virtual machine. Go to Tools – > Vnic Manager

Creating the Virtual nics

2.In this wizard, Just click on ” Next ” and enter the number of vnics that you want.Click on generate to create a new vnics.

VMNIC creation

That’s it. These mac address will act as virtual NIC and it can be mapped to any network ports.
