My problem is that the ssvm will not ping anything on the management
network, It will not do dns lookups as it will not ping past the default
public gateway. The ssvm is up and I can ping the public ip from a
different subnet.
If i remove this I can use external dns and the ssvm can ping anything
public
8.8.4.4 172.16.0.1 255.255.255.255 UGH 0 0 0 eth1
8.8.8.8 172.16.0.1 255.255.255.255 UGH 0 0 0 eth1
I change the values as Geoff had suggested and I rebooted the management
service. Then i destroyed the ssvm so it would be recreated with the new
changes. Here is the route as it is now and not working.
root@s-9-VM:~# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 216.249.111.1 0.0.0.0 UG 0 0 0 eth2
8.8.4.4 172.16.0.1 255.255.255.255 UGH 0 0 0 eth1
8.8.8.8 172.16.0.1 255.255.255.255 UGH 0 0 0 eth1

172.16.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth3
216.249.111.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
To me it doesn't look like the use external dns setting to true didn't
do anything. It sill wants to tell the dns to go across the management
network. That would be fine if the routes to the management network worked.
I'm willing to pay someone to help me at this point.

You don't need gateway for network in the same subnet on an interface.
You never told us what your real problem is (i think), so why not start by
telling us what is not working :-)
As i tried to explain, 8.8.8.8 and 8.8.4.4 will be routed over the mgmt
interface if it's entered as the internal dns. If that is your problem, try
changing the value Geoff suggested.

Erik that would be fine but this is wrong, this means its going to route
over the public address as 0.0.0.0 points to my public gateway.
172.16.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1

If you use the same dns servers for both internal and external it will add
a route over mgmt interface.

I destroyed the VM so it would create a new route. First off the 8.8.8.8
and 8.8.4.4 should have a default gateway of 0.0.0.0 if its to use the
public address to get dns. If its supposed to use the management network
then the 172.16.0.0 0.0.0.0 should be 172.16.0.0 172.16.0.1
This way it doesn't route properly

Still not sure where I should put this. I know its the way that Im
connecting to it but what route should it take? I'm thinking it should be
172.16.0.0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
