What's my goal? Right. I have 3 networks that cannot talk to each other for "reasons". Mostly because we have a test system that utilizes the same IP addresses (ORACLE Reasons) and we test & demo software in Prod, Demo, & Test networks.
I just did a foundation on my system because I did an upgrade and the networking customization I had to do with OVS changed and wouldn't work anymore.
Now that I'm working on a new install, I'm having trouble configuring the network and getting issues I didn't have before.
I've created and recreated several times using different varieties of below commands and still same outcome. Some commands below are from various tries, but same result.

Hi @srslol
Lets see if we can get some eyes on this post. Thanks

Can you review KB 4611: https://portal.nutanix.com/#/page/kbs/details?targetId=kA032000000bn1OCAQ?
In previous cases I've seen following scenario 2 will resolve the issue. Also if it is AOS 5.5 or higher use the command `manage_ovs --bridge_name br1 create_single_bridge` from the local CVM to create br1.

Hi @Bensation , actually running Version5.1.3. I'm thinking it would be smart to jump up to 5.5.
This is my foundation config here.

Can you confirm the following:
If there is still an issue it would be best to have support take a look. Do you have a valid contract? If so, open a case and PM me the case number. We can hop on a WebEx to get it squared away.
- Confirm the br1 exists on the node that the VM is booting on: "allssh manage_ovs show_bridges"
- Remove the bridge completely with "ovs-vsctl del-br br1" then recreating it with "ovs-vsctl add-br br1"? Then we apply the update_uplinks and net.create commands.
- Confirm that all hosts have connectivity to all CVMs. On each CVM run:

I decided to remove my new bridge fully and do an upgrade to 5.5.2.2 from the Upgrade Software menu. I'm now upgrading Hypervisor. Once that's done, I'll retry everything from scratch using the above command "manage_ovs --bridge_name br1 create_single_bridge" and go down that path. If not, I'll open a case and do that, which I fully appreciate you offering to take a look!!!
Sounds good @srslol keep us posted and if you do call support consider sharing the solution on this post to help others in the community. 
So, this is interesting. I upgraded AOS and Hypervisor.
I added the br1 with no problems with: allssh "manage_ovs --bridge_name br1 create_single_bridge"
When I go to add eth0 to br1 (new bridge) this happens:

Attaches just fine to the VM.
Okay. So. Uh, this was the point where I was expecting an error and it actually worked, got the vlan DHCP just fine and now my life is complete.
So upgrading did the trick.
You guys, thank you so much. I appreciate how much you guys help us newbies out. Really.

Error when powering on VM with virtual NIC
Operation failed: InternalException: kNetworkError: OVS error (10.1.16.103 create_local_port): Error not a valid bridge: br1
To resolve the issue, verify that the bridge is created on all AHV hosts within the cluster. See AHV Networking Best Practices Guide.
Verify that the bridge exists on all hosts in the cluster using the following command from any CVM in the cluster.
Scenario 1
In the following output, bridge br1 does not exist on host 10.1.1.12.
Output
Resolution
Follow the steps listed in AHV Networking Best Practices Guide to create bridge br1 on host 10.1.1.12.
Scenario 2
In the following output, bridge br1 exists on all hosts. But an error message still appears indicating that the bridge does not exist when powering on a VM.
Output
Resolution
Restart the Acropolis service on the current Acropolis master CVM. In cases where the list of bridges is not updated until a host reconnects to the Acropolis master CVM, restart the Acropolis service on the master to update the bridges. This issue affects AOS version 5.0.x and 5.1.x.
1. Determine the current Acropolis master by running the following command from any CVM in the cluster.
· Connect to the acropolis master CVM through SSH.
· Verify all CVMs and cluster services are in the up state.
· On the acropolis master CVM, stop the Acropolis service and then restart the service.
