Thanks for the script.
Maybe I am being paranoid or I have messed up my setup but since yesterday
I cannot use VNC console.
I get the following:
Error: Unable to get VNC console for instance
"7874ca62-d756-43cb-90ad-1c25ea781723"
Any idea what may have led to this issue. Thanks much.

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out-of-date.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

I resolved the 2nd problem by using "virsh undefine

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.
