Can you remove the entries from vm_instance table and then try deleting the POD.   

Thanks and Regards,

@Edison - That's the state we're currently in.  The zone is disabled.  We basically removed
everything starting with secondary storage.  So we removed Secondary storage, Primary storage,
Hosts, and Clusters.  We now can't remove the pod (or zone) because of this error.

@Sailaja - That query returns ~2800 rows, but no private IPs are assigned.  However, it looks
like all of them are stuck in an Expunging state.  Can I just remove those from the database?

mysql> select state,COUNT(*) from cloud.vm_instance;
| state     | COUNT(*) |
| Expunging |     2803 |
1 row in set (0.02 sec)

@Geoff - See above, we have been able to remove everything up to the pod level, including
system VMs and even the hypervisors (hosts).  

At this point, with no hosts added, I can't see any possible way an IP is actually being used.

Thanks guys for the quick responses.

 When deleting a Zone, I always put all Primary Storage and Hosts into Maintenance, then destroy
all VMs, but I find sometimes you have repeat the destroy process as the System VMs get recreated
 even when everything is in maintenence mode.

deletion will fail If there are any system VM entries with the state of expunging .

server with no luck.  The odd thing is the only VMs even built were the system VMs, we haven't
even attempted to build or spin-up any instances ourselves.  Like I said, we're still trying
to get the networking piece configured properly.  Are there any other suggestions on what
we could try?  It wouldn't be a big deal to just rebuild the management server but I'd like
to figure this out for when it's a prod machine and I have something like this crop up.
