How to setup Bridged Network to my dhcp server (pfsense) exampel interface: eno1 How to connect opennebula machines to real lan?

You will need to use bridged networking and setup a Linux bridge first of all, for your virtual networks set these up as ethernet , this way opennebula won’t manage the IP addressing and the DHCP broadcast will reach your DHCP server / device .

Can you send some more info , your hosts network config

So for example change your ethernet to a bridge first of all (not sure if you are using netplan can’t remember when they introduced it), change IP accordingly


auto lo
iface lo inet loopback

auto br0
iface br0 inet static
bridge_ports eth0
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off

Then in opennebula you create a new virtual network , set physical port as br0 then type ethernet , should L2 then.
