Given this node is your laptop, I assume the OpenStack environment is for testing.

If that is the case, have you considered running a VM? (using Virtual Box for example) You can add virtual
NICs to VMs for testing.

Something like RDO on top of CentOS or Fedora would get you going quickly. There's also DevStack for Ubuntu.

Hi,

I am setting up Grizzly in single node on my laptop running Ubuntu
12.04 Desktop 64-bit for POC, I am using a doc which say 2 NICs are
required (please see
https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_SingleNode/OpenStack_Grizzly_Install_Guide.rst
doc).

I have two NICs in my laptop one is Ethernet and other is Wireless so
is it fine to setup the environment on it ? Another thing, what if I
am disconnected from any of the network because then I don't have IP
in that specific NIC ?

Please see the result of ifconfig below (when network is connected):

So my OpenStack environment would be working in case IP is not
available on any/both of the NICs when network is disconnected ?
Please suggest.

Thanks,
Devendra Gupta
