So I had everything working on the VMBRs while setting up a few days ago. There is a baremetal proxmox install with a few NICs and a couple of VMs. The Opnsense router has passthrough and is working fine and I can access it plugged into the switch. The Unifi network controller and subsequent VM creation is an issue.
The Event Occurred when I set up a Unifi controller. It launched and acquired a network ip easily. While configuring it, something strange happened. I added one port to a VLAN and then suddenly a cascade of events. The devices unadopted or appeared to, and I lost connection to the unifi network host. I thought this was a misconfiguration so I changed the ethernet on the port to something I didn't touch but the ip still wouldn't renew and I couldn't force it to get a new one automatically in the VM.
Oddly enough, the Proxmox host remains reachable on it's vmbr0 with a static ip and the opnsense router with passthrough is fine. A mgmt vlan on a vmbr I am worried about... but,
Because the unifi holds the last config and it was during an initial configuration that this happened, my network is "functional"
So today, I rebuilt the VM from scratch. However, ubuntu running on the vmbr for the VMs still can't get an ip and I feel dumb for having deleted the original VM because the issue persists regardless.
Running 'ip a' shows that the link is down. Even applying ip address add and then putting the link up didn't work as a temporary method
I have built other VMs and used other NICs on different VMBRs on this machine and others to test out the functionality but still it is down and refuses to activate. I went into the .YAML file and found that the network config shows disabled.
I have tried a few theories but none seem to make sense because it all worked and then suddenly the VMs are treating the VMBRs like they don't exist. Any ideas are greatly appreciated
