I am having some problem in managing my ESX server installation at my company.
While setting up a virtual server, I am continuously getting the following error.
00:0c:29: ac: ea: 10 is not an allowed "VPX" assigned Ethernet address.
Invalid MAC address specified.
Failed to configure ethernet0.
I tried changing the Mac address by editing the "vmx" file manually, but this still not help.
I don’t know how to manage all this trouble as I tried many simple ways, but still I cannot able to figure out the problem that is preventing me from solving it.
ESX Server version 4.0 is used on a machine having dual Xeon processor and 16 of ram. Storage is on SAN which is MSA 1000.
ESX Error: Invalid MAC Address
You will get this error when you virtualized a system and use the old MAC address. You will also get a “XX:XX:XX:XX:XX:XX is not an allowed static Ethernet address” error message when you try to boot the VM. This is because some software still ties license keys to MAC addresses. By default, VMware only allows a virtual machine to use a MAC address in their assigned range.
Try doing this:
Add the following line to the VMX file for that VM:
Ethernet0.checkMACAddress = “FALSE”
This will disable the MAC checking when powering on the VM.
It would really help if you have the following configurations:
Ethernet0.checkMACAddress = “false”
Ethernet0.addressType = “static”
Ethernet0.Address = “00:0C:29:B0:27:E1″
Make sure also that you:
Remove virtual machine from inventory.
Download the vmx file from datastore to local drive.
Delete vmx file from datastore.
Edit the vmx file with Notepad++ with configuration settings above.
Upload the new vmx file to datastore.
Regi ster the vmx file with ESX server.
