Bug Description

In some cases, the use counter is not properly decremented, so a cached image is not being flushed from the cache (or deleted from the disk). This does not cause any catastrophic failure, but does waste resources.

  [ Dustin Kirkland ]
  * debian/eucalyptus-url, debian/eucalyptus-cc.install,
    debian/eucalyptus-cc.links, debian/eucalyptus-cc.postinst::
    - fix whitespace, to match other update-motd urls LP: #450449
    - link to ubuntu.com/cloud, which links to our documentation,
      necessary for new UEC admins
    - ensure that it gets installed with executable permissions,
      LP: #444970
  * debian/eucalyptus-udeb.finish-install: fix typo; fix breakage of
    /etc/network/interfaces when nodes are configured with static IP
    addresses, LP: #446023

    eucalyptus-cloud.eucalyptus-walrus-registration.upstart,
    eucalyptus-sc.upstart, eucalyptus-walrus.upstart, rules, control:
    - registration of cc/sc/walrus should *only* ever occur on the CLC,
      so these scripts should be moved to the eucalyptus-cloud package,
      LP: #450815
    - starting cc/sc/walrus should *not* depend on eucalyptus-cloud
      running, since these components can be installed on separate
      machines, LP: #450777
    - but if cc/sc/walrus are on a system doing registration, ensure that
      these jobs kick off when "starting" registration
    - allow for whitespace separated list of $CC_IP_ADDR and $SC_IP_ADDR,
      as there can be more than one of these, and admins in multi-cluster
      or multi-component mode would need to register a list
    - use Replaces to ensure upgrades work properly
  * debian/eucalyptus-ipaddr.conf: update inline documentation accordingly
  * debian/eucalyptus-cc.templates: update public_ips instructions in the
    installer to match the new upstream implementation, LP: #438565
  * eucalyptus-common.eucalyptus.upstart: fix unclean package purging,
    which hangs on stopping eucalyptus service

    - LP: #398867 - fix storing VLAN tag info from web ui
    - LP: #430266 - fix setting of HTTP error codes
    - LP: #449948 - part of fix to LP:#449948 the CC now correctly sets the

      VNET_PUBLICIPS field of eucalyptus.conf
    - LP: #449143 - Add the 169.254.169.254 address to eth0 as 'scope link'

Bug #447585 :
Similar issues were observed but not with the euca tools. The de-registered images does not get displayed on executing euca-describe-images command but the similar changes are not reflected on eucalyptus UI. The status of de-registered and deleted images is displayed on eucalyptus UI as de-registered.

Is it a bug? or is there a way I can remove entries of de-registered images from eucalyptus UI?

Also, to bundle a new image using make-me-an-image utility the image size required is atleast 10 GB .

Not sure if this is related to this bugrep, but if installation of images from the UI fails and only the eki-XXXXXXX file is displayed - no emi or eri image/ramdisk is displayed, how do I NOT get these to display on the UI?

I'm running eucalyptus 1.61 both cc and nc on a single PC to try it out.
