After the dashboard issues were resolved yesterday I run into the following problems:<BR>
<BR>
1- Now eventhough my dashboard interface looks ok I still keep getting the red box errors on top of my main page:<BR>
</SPAN><FONT COLOR="#FF0000"><FONT SIZE="4"><SPAN STYLE='font-size:14pt'><B>Error: </B>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.<BR>
</SPAN></FONT></FONT><SPAN STYLE='font-size:11pt'>What am i missing here?<BR>
</SPAN><FONT SIZE="4"><SPAN STYLE='font-size:14pt'><BR>
</SPAN></FONT><SPAN STYLE='font-size:11pt'><BR>
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.<BR>
