2014-10-14 11:28:49 -0500 commented answer If I use nova-network, is floating IP the only way to go?

I am not sure if I completely understand. My nova VMs use 10.0.0.x. I don't have any control with the company network 192.168.253.y. I think it's just a dhcp network. Are you saying that I can usenova.fixed_ips table to reserve some 192.168.253.y's addresses? Could you show an example? Thanks!

I need to access my VMs from the wifi network they are on.

It's like this:

my wifi network is on 192.168.253.x. I don't have a way to reserve addresses to use as public ip address pool.

I have a single host devstack whose address is 192.168.253.162/10.0.0.1. VM's are 10.0.0.x (x starts from 2).

I can access the wifi network from the VM. But the issue is that I need to access VM from the wifi. For example I need to rdp to win7 10.0.0.2 from mac 192.168.253.80.

I did extensive experiment and seem to me the only way for this to work is I have some 192.168.253.y reserved as floating ip. I don't have the ability to do so.

Am I right? Is there a way to make it work with nova-network?

I think neutron should work but I am not sure how to configure a virtual router in devstack to make it work.

Thanks!

add flat-interface = vnet0/ or whatever interface you got after you create an instance.

I don't think virbr0 is but if you don't see any other UP interface, try virbr0
