2015-02-06 01:00:17 -0600 answered a question how to find out which version of OpenStack is installed

on openstack node cli:

dpkg -l | grep nova-common

lets say the following output

ii nova-common 1:2014.2.1-0ubuntu1~cloud0 all OpenStack Compute - common files

check for the above release version i.e 2014.2.1 in the following link:


I can see that above version is Juno

Reinstalled oslo with the command: pip install --upgrade oslo.rootwrap This worked for me

2013-05-02 01:23:53 -0600 asked a question public net with single ip cannot be uplinked

I'm trying to create a public network (in a test lab where we get the ip addresses through DHCP, hence I limited the public network to /32 cidr range) I'm trying to map this public network to my router in quantum I'm getting the following error:

"No more IP addresses available on network fca44fe9-0afb-4458-985e-12ae876b5494"
