Reading the wiki it looks like it's an "Ubuntu 10.10 x64_86 image (no
ramdisk) modified with local user account". Apparently it sets the
ubuntu user password to "ubuntu", and allows passwordful SSH. Given the
rest of the instructions that should not be necessary, so this should
probably be fixed.

Hi all,

We can reproduce the problem in our environments with the images downloaded
from  http://uec-images.ubutu.com :-(

Does anyone know what this image is ?
I'm guessing that Muhammad found reference to it from
http://wiki.openstack.org/GettingImages . The page there mentions
http://uec-images.ubuntu.com, but the code snippit points to something on
http://c0179148.cdn1.cloudfiles.rackspacecloud.com/ .

I'm happy that people find the uec-images.ubuntu.com images useful, and
one reason that we put the files there is so that people can easily use
them as a starting point for recreating images.

However, if there is something that was insufficient about the official
ubuntu images, I'd like to know what it was so that we can make them
better.  What was it that caused someone to create
"ubuntu1010-UEC-localuser-image.tar.gz" ?

Just curious, where did you see that you should do this? If possible, I'd
like to address the source of the issue, so that people don't have to do
such arcane things.  http://pad.lv/719418 is one such bug that has been
fixed.

This seems like a good opportunity for simplification.  Anyone interested
in contributing a nice wrapper to http://launchpad.net/cloud-utils ?

Personally, I think that "bundle-vol" should have stopped after creating
the .img, and then have the user use euca-bundle-img and
euca-upload-bundle, then it would not need credentials itself.  And then,
you could use the (more sane, imho):
   uec-publish-image amd64 ubuntu-1010-rebundle.img ubuntu

as a wrapper around your next two commands.

(I realize euca2ools copied ec2-api-tools here, but that doesn't mean i
can't complain).

If i had to guess, based on nothing else, I suspect that there is an entry
in /etc/fstab for a device that is not present.  mountall will sit and
wait until the proverbial cows come home for it to appear.  The solution
is to put 'nobootwait' in the options field for entries in /etc/fstab that
may not be there on boot.

An /etc/fstab from your re-bundled image would confirm or refute my
assertion.

Thanks for the tip.. The Ubuntu image from http://uec-images.ubutu.com did work 
and rebundled successfully following the same steps.

Any chance you could reproduce with an official Ubuntu image (downloaded
from http://uec-images.ubuntu.com/) and file a bug on Launchpad ? This
looks like a guest issue and with official images we  can get help from
Ubuntu cloud image developers if need be...

[Openstack] Problems with re-bundle

[Muhammad Atif]

Hi Openstack gurus,

We have recently shifted from eucalyptus to openstack and so far, finding it 
quite stable. However, we are having terrible time re-bundling an existing 
image. 

The re-bundled image is able to complete the boot process upto mountall: but 
the 
cloud-init never fires up.

Here is what we have done so far, please let us know what exactly is wrong on 
our side.

1- Downloaded the ubuntu1010 image from openstack site as follows: 
wget 
http://c0179148.cdn1.cloudfiles.rackspacecloud.com/ubuntu1010-UEC-localuser-image.tar.gz

2- publish this image:
uec-publish-tarball ubuntu1010-UEC-localuser-image.tar.gz ubuntu x86_64
3- Now we run the image using euca-run-instance and it boots up fine, we are 
also able to login using the private key and able to install software.

4- When we want to save the instace into an image (rebundle), following 
sequence 
is performed

-   rm -r /etc/udev/rules.d/70-*

-   copy the nove certificates and source .novarc

-   euca-bundle-vol -c ${EC2_CERT} -k ${EC2_PRIVATE_KEY} -u ${EC2_USER_ID} 
--ec2cert ${NOVA_CERT} --no-inherit --kernel aki-0XXX -d /mnt -r x86_64 -p 
ubuntu-1010-rebundle -s 2048 -e /var/lib/dhcp3 


-  euca-upload-bundle -b ubuntu -m  /mnt/ubuntu-1010-rebundle.manifest.xml

   -  euca-register ubuntu/ubuntu-1010-rebundle.manifest.xml

5- Now we fire up this image once it has been successfully uploaded; we get 
stuck after plymouth-splash. Comapred to the original image which started 
cloud-init after this point. The image is replying to pings but refusing ssh. 
It 
can be some odd ssh key issue?

Any help is greatly appreciated. I am willing to provide you with other logs if 
requested.

Atif
