This is a message we have received while powering up our vMA template. The reason for this is that there isn’t an IP pool defined for the network adapter where vMA was plugged in to.
The solution is simple, click on your Cluster node within your vSphere client – click on IP Pools tab and then create an IP pool associating it with your physical NIC. This would assign an identity to your network adapter.
After creating the IP pool, you should be able to power on your appliance.
