Description

I have a guest network that I recently added an additional IP range on a different subnet to. When I try to deploy a VM while specifying an IP in that new IP range it fails to deploy with the following error:

This looks very similar to CLOUDSTACK-3871, but if I'm reading the fix correctly it only applied to XenServer.
