I've also had to run the following before.
Might be useful for others. Might be a bug somewhere that causes them to be leftover...

$ more clear-domains.py
import libvirt
import sys

connUri = "qemu:///system"
conn = libvirt.open(connUri)

if(conn == None):
    print("Could not open connection to " + connUri)
    sys.exit(1)


definedDomains = conn.listDefinedDomains()
am = len(definedDomains)
print("Found %s leftover domains" %(am))
print(definedDomains)

if(am):
    print("Clearing %s domains" %(am))
    for domain in  definedDomains:
        print("Found domain " +domain)
        dom = conn.lookupByName(domain)
        print "Clearing domain id %d running %s" % (dom.ID(), dom.OSType())
        print(dom.info())
        dom.undefine()

It is likely that one of devstack, nova, openstackx, or dashboard are out-of-date.  You should update those directories, and then re-run stack.sh

I resolved the 2nd problem by using "virsh undefine instance-00000002". Still have the 1st problem.

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.
