Forget HA (for a while) and focus on the IP address problem. Start from scratch with a new VM, and/or inspect one of your VM's where the networking works. Find the difference.

Could it be that you need to run the VM network in NAT mode, instead of a "Bridge" mode?
Please note, I have little experience in troubleshooting these, I'm just spitballing ideas here...
No, then the VMs would get their own subnet. You want the NIC bridged so that the router actually sees the VMs.
Gotcha. I learned something new. Thanks :)
output from "nmcli device status" command:
DEVICE TYPE STATE CONNECTION
virbr0 bridge connected virbr0
so i assume its in bridge mode?
Not an expert, just something I did and learned from; does the hardware you're running on have more than one ethernet port (enp#...)? Is it possible you've selected the wrong one?
Also I notice my VMs in proxmox have the bridge nomenclature of vmbr0 (not virb0). Perhaps something there?
Just throwing ideas out there, I'm pretty new at this.

OP, are all of the working-as-expected VMs also members of the virbr0 network?
I'm thinking that this is a firewall issue on your VM host. If you DO NOT have any other working VMs then could you try disabling the firewall on the VM host and see if the VM can receive DHCP traffic.
I currently have no other VM's running. I'll see if disabling the firewall helps.
Did you ever figure out what was causing your issues?
No sadly I didn't. I got it working a few times after reconfiguring everything but it never survived a reboot.
When I ran all my vms in kvm I used macvtap for the nic type.
