[ovs-discuss] Is there a way to allow Promiscuous mode for a VM connected to vnetX on OVS?

[Dmitri Chebotarov]

Hi

I'm looking for some help with an OVS option – is there a way to allow interface of connected VM to operate in promiscuous mode?
VMWare vSwitch has this under Security, VirtualBox under Network->[Adapter]->Advanced->Promiscuous mode.
It's in Deny by default – is a way to change it to Allow for specific VM port on OVS?

I'm trying to build a bridge between two locations/sites to extend my network to a different location (cloud).
The bridge is running inside VMs, VMs are hosted on KVM (RHEL6) /w OVS (v1.10).
I get broadcast traffic reaching to other sides on VM0, but in never leaves eth1 interface and VM on the same L2 network don't 'see' it.
I can confirm it with tcpdump.

I'M attaching a quick diagram – I hope it doesn't make it look more complicated that it's :)
All VM0/1/n are Ubuntu 12.04 guests running on KVM.

I'Ve duplicated the same setup on my local WKS using VirtualBox and all works as expected ONLY WHEN I allow promiscuous mode for the corresponding adapter for eth1 on VM0.

I cannot find a way to allow promiscuous mode for corresponding vent adapter on KVM/OVS (VM0:eth1).
Tried 'ifconfig vnetX promisc', but I don't think this is correct.

Thank you for the help.
