Proper way of setting a static MAC for a vm running on VC 2.5 with ESX 3.5 hosts

Jump to solution

Greetings,

Could someone tell me if setting a static mac address via the VMware VC client - under the vm's Edit Settings > Network Adapter > MAC Address - set to manual the most recent accepted way of doing it. (since we're running VC 2.5 and its in the GUI).

I've seen manal settings by editing the vmx settings file (requires you to remove the vm from the VC's inventory. Is the above the new accepted way if you are using Vmotion or is this GUI setting a moot point?

Thank you,

dhayashi

Hello,

If the MAC is one of VMware's MACs then you can set it within the VIC or directly within the VMX. Just make sure the VM is powered down when you go to change the VMX. If it is not one of VMware's MACs then you will need to have the Guest OS change the MAC. There are plenty of tools that can do that.
