VMWare ESXi force MAC Address re-generation

Thursday, April 2nd, 2015

This is on 5.1u2

I don’t know how this happened as I am doing these steps every time, yet today the newly created VM with added templated disk is getting the same MAC address every time.

I tried the solutions with deleting those 5 entries form the fwx file, to no avail.

The next logical thing to do is to move the VM to another folder. I simply renamed the VM container folder. And that solved my problem.

BUT, renaming the folder back, surprise, gets the old MAC address and UUIDs back! I don’t know why and I don’t have time to figure it out, so I just leave it in new folder and choose “I copied it” when powering on the VM.
