I want to connect my OpenNebula hypervisor node physical network interface to VM directly so that VM can send traffic to hypervisor network. is there any way out for this solution?

Hello @mosharaflink

I don’t know if I understand well, but if you want to connect VMs to the interface which is connected to the physical network, you can use linux bridges, [here](http://docs.opennebula.org/5.8/deployment/open_cloud_networking_setup/bridged.html) you can find more information.

@ahuertas. Yes you got my point of networking which is connecting VM networking with host access network. But the link given for bridging does not has enough information for the configuration.

Hi,

Please post here the following output:  
$ brctl show
