The VMWare vCenter Appliance is a quick and easy method of deploying vCenter. But as with any 1.0 release there are many features which people are looking for before utilizing in a production environment, beyond the third-party plug-in, update manager, linked-mode, ect there is a lack of ability to support multiple network cards. When checking on the web interface for the vCenter Appliance administration there is no ability to address more than one network card.
Luckily this can be corrected with use of the command line.
- Edit your vCenter Appliance and add the additional network card (VMXNet3)
- Via the vCenter Appliance console login locally with root
- cd /etc/sysconfig/network
- cp ifcfg-eth0 ifcfg-eth1
- vi ifcfg-eth1
- Update the device to be eth1 and correct the IP addressing information
Now the vCenter appliance will be available on two addresses in potentially different subnets.
