Linux FAQs with Answers--How to set a static MAC address on VMware ESXi virtual machine
|
||
|
|
================================================================================
|

|
|
> **Question**: I want to assign a static MAC address to a virtual machine (VM) on VMware ESXi. However, when I attempt to start a VM with a static MAC address, the VM fails to start and throws an error "00:0c:29:1f:4a:ab is not an allowed static Ethernet address. It conflicts with VMware reserved MACs". How can I set a static MAC address on VMware ESXi VMs?
|
||
|
|
|
||
|
|
When you create a VM on VMware ESXi, each network interface of the VM is assigned a dynamically generated MAC address. If you want to change this default behavior and assign a static MAC address to your VM, here is how to do it.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
As you can see above, VMware's vSphere GUI client already has a menu for setting a static MAC address for a VM. However, this GUI-based method only allows you to choose a static MAC address from **00:50:56:xx:xx:xx**, which is VMware-reserved MAC address range. If you attempt to set any arbitrary MAC address outside this MAC range, you will fail to launch the VM, and get the following error.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Then what if I want to assign any arbitrary MAC address to a VM?
|
||
|
|
|
||
|
|
Fortunately, there is a workaround to this limitation. The solution is, instead of using vSphere GUI client, editing .vmx file of your VM directly, after logging in to the ESXi host.
|
||
|
|
|
||
|
|
First, turn off the VM to which you want to assign a static MAC address.
|
||
|
|
|
||
|
|
[Enable SSH access to your ESXi host][1] if you haven't done it already. Then log in to the ESXi host via SSH.
|
||
|
|
|
||
|
|
Move to the directory where your VM's .vmx file is located:
|
||
|
|
|
||
|
|
# cd vmfs/volumes/datastore1/[name-of-vm]
|
||
|
|
|
||
|
|
Open .vmx file with a text editor, and add the following fields. Replace the MAC address field with your own.
|
||
|
|
|
||
|
|
ethernet0.addressType = "static"
|
||
|
|
ethernet0.checkMACAddress = "false"
|
||
|
|
ethernet0.address = "00:0c:29:1f:4b:ac"
|
||
|
|
|
||
|
|
Now you should be able to launch a VM with the static MAC address you defined in .vmx file.
|
||
