Change VM MAC Address

Jump to solution


We just P2V'd a server into an ESXi 5.1 cluster and I need to keep the original MAC address for licensing reasons.I added the lines below to the .vmx file.

ethernet0.checkMACAddress = "false"

ethernet0.addressType = "static"

ethernet0.address = 00-24-E8-7A-51-B0

But when I power on the VM, I get this error. How can I change the MAC to keep the original MAC from the physical server?

An error was received from the ESX host while powering on VM servername.

Failed to start the virtual machine.

Module DevicePowerOn power on failed.

Could not set up "macAddress" for ethernet0.

Invalid MAC address specified.

"00-24-E8-7A-51-B0" is not a valid Ethernet address.

Thanks,

Scott
