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):
root@devendra-HP-ProBook-6460b:/home/devendra# ifconfig -a
eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx

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
