After the dashboard issues were resolved yesterday I run into the following
problems:

1- Now eventhough my dashboard interface looks ok I still keep getting the
red box errors on top of my main page:
Error: Unable to get service info: This error may be caused by a
misconfigured Nova url in keystone's service catalog, or by missing
openstackx extensions in Nova. See the Horizon README.
What am i missing here?


2- I am not sure if this is related to the changes or something on my part
has been modified incorrectly but trying to create a vm everything seems to
be going fine until I see the following errors essentially saying there is
a instance with the same name already and the vm does not get created. What
am I doing wrong? The nova/instance directory is empty and since I start
with devstack, the nova tables are all empty in the database.
