Multiple vCenters-how to avoid duplicate MAC address of virtual machines

If we have multiple vCenters in virtualization environment , there would be a possibility of issuing same MAC address to different virtual machines from different vCenter servers.

How we can avoid this kind of issue?

When we are installing vCenters it will automatically generate instance id for vCenter.We can check th vCenter servers ID from web client.

If multiple vCenter servers use same Instance ID , there will be a possibility of having MAC duplication problem. In this case we can change one of vCneter servers Instance ID from web client.

Some fo the usefull features in vCenter

There are some of the vCenter features we don’t use , but these are very useful.In this article I’m going to show some of these.

1. Update file to service request

This option is coming under Administration

Using this feature we can easily upload log/support bundle directly to the VMware. We should know only the service ID.
