Following a copy of some VMs from one infrastructure to another, I seem unable to get the VMs to generate new vCenter Mac addresses with the Runtime ID of each new vCenter instance.
I followed this guide:-
https://kabri.uk/2008/07/16/force-vmware-to-generate-a-new-mac-address/
and removed these entries in the VMX file:-
ethernet0.addressType
uuid.location =
uuid.bios =
ethernet0.generatedAddress =
ethernet0.generatedAddressOffset =
Now the VM does get a new MAC, but NOT the one with the vcenter ID in it, it gets a different one, something like 00:50:56:9d:52:05 which bears no correlation to the vCenter ID.
ALso instead of being set to "VPX" which would indicate a vcenter generated MAC, this setting gets set to "generated".
Slightly confused as to how I can force a MAC change allocated by vCenter instead of this "generated" address.
We run dVswitches, do I have to remove the VM from the inventory and re-add? We would lose all the performance data and this might mess up our MABS backups.
Anyone any idea how I can force vCenter to properly allocate a MAC to these VMs with its proper ID?
Thanks, its driving me crazy.
