n
A virtual machine has been transferred in power-off state from one vCenter Server instance to
another in the same network, for example, by using shared storage, and a new virtual machine
network adapter on the first vCenter Server receives the freed MAC address.
Solution
n
Change the MAC address of a virtual machine network adapter manually.
If you have an existing virtual machine with a conflicting MAC address, you must provide a unique
MAC address in the Virtual Hardware settings.
n
Power off the virtual machine, configure the adapter to use a manual MAC address, and type the
new address.
n
If you cannot power the virtual machine off for configuration, re-create the network adapter that is
in conflict with enabled manual MAC address assignment and type the new address. In the guest
operating system, set the same static IP address to the re-added adapter as before.
For information about configuring the network adapters of virtual machines, see the vSphere
Networking and vSphere Virtual Machine Administration documentation.
