Unable to deploy initial zone/setup - Fails at creating guest network #10671

problem

We are trying to setup CloudStack on a single DL380 and setup the initial first zone (and eventually add more KVM hosts that are ready). When running through the setup we find the following error:
Creating guest Network | Something went wrong; please correct the following: Provider VirtualRouter is either not enabled or doesn't support service Dhcp in physical network id=211

I tried to click on "Fix errors" but it brings me back to storage networks tab. After this, the setup keeps looping on the setup.

I had a look at the management-server.log file but don't see anything jump out.

Some context:
Host with 2 bridges configured to physical adapters:

• cloudbr0 = management & storage traffic on VLAN 1451
• cloudbr1 = guest on VXLAN VNI 5000 (also tried VLAN isolation for guest, same error)

Storage:

• Local NFS server at /export/primary and /export/secondary

Log file

See line 30819 for instance
management-server.log
