Esxi mac error

Intro

In vmware ESXi You can get some auto-generated address when creating new VM NIC.

The weird issue

This works just fine, unless You want to import the VM on different host. Then, an error message will appear, saying that the MAC address is reserved.

Solution

Navigate to .vmx file of the VM. Add this to the end of file:

ethernet0.checkMACAddress = "FALSE"
ethernet1.checkMACAddress = "FALSE"

ethernetX.checkMACAddress = "FALSE"

*WHere X is the eth number.

Explicitly set the MAC:

ethernet0.address = "00:0c:29:00:00:00"
ethernetX.address = "00:00:00:00:00:00"
