<font size=2 face="sans-serif">Many of the templates in the heat-templates
project have built-in expectations of image names; here is an example excerpt:</font>

<br><tt><font size=2> F18: {'32': F18-i386-cfntools, '64':
F18-x86_64-cfntools}</font></tt>

U10-x86_64-cfntools}</font></tt>
<br><tt><font size=2> RHEL-6.1: {'32': rhel61-i386-cfntools,
'64': rhel61-x86_64-cfntools}</font></tt>
<br><tt><font size=2> RHEL-6.2: {'32': rhel62-i386-cfntools,

<br><font size=2 face="sans-serif">From where should a user get these images?
I have discovered --- I do not even remember how --- that there are
some images with names like those in </font><a href="http://fedorapeople.org/groups/heat/prebuilt-jeos-images/"><font size=2 face="sans-serif">http://fedorapeople.org/groups/heat/prebuilt-jeos-images/</font></a><font size=2 face="sans-serif">
. Is that the right source? Is that documented anywhere?</font>
<br>
<br><font size=2 face="sans-serif">That directory contains only Fedora
images. From where are we expected to get the Ubuntu and RHEL images?</font>
<br>
<br><font size=2 face="sans-serif">That directory does not contain Fedora
20 images. Should they be added? I am willing to do the work
if that is the right thing to do; how would I create those images?</font>
<br>
<br><font size=2 face="sans-serif">Do we still need to build special images?
Recent releases of Ubuntu and Fedora have cloud-init built in; I
assume the same is true for RHEL.</font>
<br>
<br><font size=2 face="sans-serif">What are good date-independent URLs
for recent Fedora releases? Steve Hardy has mentioned </font><a href="http://cloud.fedoraproject.org/fedora-20.x86_64.qcow2"><font size=2 face="sans-serif">http://cloud.fedoraproject.org/fedora-20.x86_64.qcow2</font></a><font size=2 face="sans-serif">
(and the obvious parallels for release 19 and for 32 bits also exist);
I know of no other date-independent URLs for Fedora 19 and 20.</font>
<br>
<br><font size=2 face="sans-serif">For releases that have cloud-init built
in, should the templates expect image names that are derived in the obvious
way from the date-independent URL?</font>

anybody had success with it? Following is an example failure I found
in nova-compute.log:</font>
