Below I have fixed the issue numbering and added one more issue.

Status: I have an image built, now I want to push it to the cloud. So I
click "push".

http://192.168.122.174:3000/catalogs/1/deployables/1

#10 problem:
I see: "Some of the images are not pushed". But no link/button/whatever
to do something about that.

#11 problem:
On more problem on the page. I see "Choose a Catalog to enable access:
", then an EMPTY combobox and then a grey button that goes blue, when I
hover it.  The button does nothing.

back to problem #11:

I was told to look into the ImageFactory log, I did.

#12 problem: Image Factory log and error message are useless from the
user point of view. That should be worked on.  Further more we have a
WUI, so having user to study the logs each time something goes wrong is
a no-no.

I was told by Jenik, that I have to change region (don't have idea why
should I, but I did) 

So I went editing the provider:

http://192.168.122.174:3000/providers/1/edit

There are interesting 2 buttons there: "Save Changes" and "Test
Connection"

I obviously first want to test, if I can so I type in my changes
(changing provide name and region" and then click "Test Connection"

I get a message telling me "Successfully connected to Provider" but my
changes are gone. Did I test the newly entered setup or the previous
one?

The workflow should be IMHO: enter changes --> test --> confirm or
decline changes

#13 problem: Clicking "Test Connections" (probably) looses my changes to
the provider "Connectivity" and (probably) tests the old configuration,
not the one just entered.

Jenik told me to rebuild the image, when I have edited the Provider
Connectivity. I believe, I have to, when he tells me.

#14 problem: If image rebuild is needed after editing the provider, then
Conductor shall take care of that. Either rebuild the image for me, or
invalidate it.

So I changed to 'ec2-us-east-1' -- have been told that the name should
match the EC2 Region.

#15 problem: Why am I entering the regions if the name matters?

Anyway the error message is again telling me nothing. But in the log I
see a new error:

ImageFactoryException: No available JEOS for desired OS, verison combination


#16 problem: I should get a SANE error message in Conductor. Not just
"push failed".  At least: "ImageFactoryException: No available JEOS for
desired OS, verison combination" provided the user knows what i JEOS is
and fixing the 'verizon' -> 'version'

I give up again, ask for help. I am told to switch from Fedora 17 to
Fedora 16. So I create a new image for Fedora 16 and this image finally
gets build and gets pushed to the EC2.

Now I am at: http://192.168.122.174:3000/images/0ca96c28-1c33-11e2-9928-525400b4f6a2

#17 problem: The fact that I actually managed to push the image (WOW!)
is not adequately 'celebrated' in the UI. I would expect something to go
green or at least blue. I just see the ProviderImage ID column and an
identifier. I have to make the connection, that it's actually right
myself.

#18 problem: there's something wrong with the page. When I open the page
the button "Push All" is light grey. Than after a while (a minute or so)
the button goes blue. Probably a duplicated code setting the button
status onLoad and then on some Ajax update? Setting different classes?


Next I launch the instance ---> OK

Then I take a look at the properties: http://192.168.122.174:3000/instances/1

I See:

#19 problem: The IP address is real, but the memory is from the frontend
profile. The backend EC2 machine has >1.5GB.
