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out-of-date.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.
