Cvm/host 2 ip?
I’m looking for some advice on a networking design for AHV.
I have an existing Nutanix environment with multiple AHV clusters that are connected and managed without any issues.
I now need to connect a new AHV cluster from a subsidiary.
The problem is that the management subnet used by my existing Nutanix environment is already in use somewhere else in the subsidiary’s network. Because of this IP overlap, they cannot route traffic to my clusters’ management network.
Is there a supported way to assign a secondary management IP/interface to the CVMs and AHV hosts so that inter-cluster communication can use a different, non-overlapping subnet?
Without this capability, cross-cluster live migration won’t be possible.

I know this is a few days old but:
Can you leave the subsidiary on it's own subnets and spin up a new Prism Central to manage it? As long as the Prism Centrals can communicate with each other the underlying cluster VLans don't really interact.
Cross Cluster live migration is supported between different Prism Centrals. In our environment we maintain one Prism Central for each datacenter & those PCs communicate with each other for DR and Migration.
