I have a multinode kilo setup with a controller, network and 2 compute nodes.

I have configured external physical network and virtual networks, but I am not able to ping external net. The openstack kilo install guide says " If you are building your OpenStack nodes as virtual machines, you must configure the hypervisor to permit promiscuous mode on the external network". So how can I enable promiscuous mode on the hypervisor level, as " ifconfig eth0 promisc " enables it on only the host level I think.

So please provide some information on what should be the next steps.
