Configure OpenStack on a WiFi-only system?

OpenStack Juno installed as per RDO onto a CentOS 7.0 Host. NetworkManager disabled and network service enabled as required.

As per RDO QuickStart instructions, the DEVICE=xxxx variable should be set in the ifcfg-xxxx network script. However, on this particular system my only IP address is via WiFi, and as such no explicit ifcfg-xxxx script exists in the traditional sense (WiFi network can be anything and can't be assumed ahead of time) - normally NetworkManager would be used to configure the address but of course this service is disabled as per RDO instructions.

looks like bridging wlan0 with eth0 has some issues. not sure why you cant just bind the openstack processes to the wlan0 interface in the configs though.

Thanks echiu for your reply. Although I think perhaps I didn't explain my question very well (or perhaps I am just missing the point). The DEVICE=xxxx and ifcfg-xxxx scripts I am referring to are all on the host - not on the VM. The RDO documentation states to make these changes (in addition to disabling NetworkManager and enabling the network service) on the host. The IP address I have on the host is assigned via DHCP and there is no corresponding ifcfg-xxxx script because of the WiFi nature of the connection, i.e. as opposed to eth0 etc.

Does that clarify things or am I somehow missing the point? I'm trying to determine how to set up the host side of things, where the host's only IP address is assigned via DHCP over WiFi.

On a wifi connection, you don't have eth0, I think the installation scripts assume you have a static IP hence bridging with eth0 fails as the other commenter pointed out.

i think the portion of documentation you are looking at assume you have more than 1 network connection for a physical machine, thus mostly ethernet devices not wifi.

i would look into devstack if you want to 'play' with openstack. also the type of networking service you need, neutron? vlans?

just read the answer above, it is correct to use virtual machine to install openstack components for testing and learning.
