Bug Description

On a fresh install of lucid eucalyptus, I did the following:

A. download lucid 20100303 (
B. publish it
   uec-publish-tarball lucid-server-uec-amd64.tar.gz lucid-20100303
C. extract
   tar -Sxvzf lucid-server-uec-amd64.tar.gz
D. mount image loopback, install a new upstart
  sudo mount -o loop lucid-server-uec-amd64.img /mnt/
  cp upstart-* /mnt/tmp
  sudo chroot /mnt
  % LANG=C
  % dpkg -i /tmp/upstart_*
  % rm /tmp/upstart_*
  % exit
  sudo umount /mnt
E. register new image with kernel from the "dist" version
   $ uec-publish-image x86_64 --kernel eki-68881AF2 \
      lucid-server-uec-amd64.img lucid-20100303-d-upstart
   emi-24C619C3 lucid-20100303-d-upstart/lucid-server-uec-amd64.img.manifest.xml

F. run instance of new image
   euca-run-instances --key mykey --instance-type c1.medium emi-24C619C3

After 1 hour 15 minutes, image was still pending
After another 30 or so, it terminated.

Note, I doubt that steps 'C' and 'D' above are required, but have not tested that.

Looking at the logs:

NC fails to get the DecryptedImage from Walrus:

walrus_request(): writing GET/Get DecryptedImage output to /var/lib/eucalyptus/instances//admin/i-3DB40784/disk
walrus_request(): wrote 30 bytes in 1 writes
walrus_request(): server responded with HTTP code 408 (timeout)
                  download retry 10 of 10 will commence in 4 seconds

It stays pending while retrying 10 times... then after a couple hours it stops trying and terminates request.

On the Walrus side:

ERROR WalrusImageManager | Tired of waiting to cache image: lucid-20100303-d-upstart/lucid-server-uec-amd64.img.manifest.xml giving up

I'm attaching steps that I did after the lucid-image steps above with a karmic image.

Note, that the karmic image has a ramdisk. This didn't seem to change anything, the karmic image fails to boot also.

I followed the attachd file (karmic steps...) on a fresh install of Eucalyptus and it recreates the problem. That seems to me to rule out the "ramdiskless" scapegoat.

Dustin and Daniel worked on this a bit more on friday and seem to have at least found a workaround. The database was getting stuck. Per Dustin, it at least appears that this is not a uec-publish-[image,tarball] as I had thought it might be.

This is the issue you and I looked at on Friday.

I believe we decided that Eucalyptus was blowing up somewhere during the image decryption, and then the cloud/database worked itself into a nasty state.

We restarted eucalyptus several times, and eventually we were able to register the very same images that were failing.

I'm assigning you this bug, as you said this was something you needed to discuss with Chris.

This bug is marked High and Confirmed because it's blocking Scott's work on creating/verifying Lucid UEC images.

I'm not sure why I'm so lucky, but I hit this more times than not...I'm almost completely unable to register an image that will boot.

It seems critical to me, as it blocks all usage of the installed UEC.

I had the exact same problem with image decryption at walrus. The kernel and ramdisk are transfered fine to the nc. After reading this bug report, I upgraded to Lucid Lynx from Karmic, yesterday. But the same problem exists.

I am struck on this from 5 days now, pleas tell me if there is any work-around available such as not encrypting the image while uploading it to Walrus.

Scott Moser (smoser) wrote :

@nipun , please open a new bug, as this one is fix-released. It really *as* fix released too, the problem that was solved was due to the manifest path including the string 'tar' in it.

Please do open a new bug and report your problem.
Ideally, use
1. recreate your failure
2. use 'ubuntu-bug eucalyptus-common' on the cloud controller to report it and have it send the logs.
