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

/etc/network/interfaces

auto lo
iface lo inet loopback

auto br0
iface br0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.1
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.

Or look at using vlans same principle
