Red Hat Product Errata RHBA-2013:0260 0 normal SHIPPED_LIVE Red Hat OpenStack 2.0 (Folsom) Preview bug fix and enhancement update 2013-02-14 23:21:02 UTC

Description Rami Vaknin 2013-01-09 11:10:01 UTC
Description of problem:
I found an identical bug in launchpad.net: https://bugs.launchpad.net/nova/+bug/1089430, but it looks like it's not going to be fixed for Folsom.

"nova network-list" command always fails in my environment, it looks like the code tries to access list in a manner it should access a dictionary.
