    5 !ImageProxy allows  independent Ecalyptus sites to create VMs with identical images. Images are identified by a URL and a GUID, representing image hash. Provided with these two parameters !ImageProxy associated with a Eucalyptus site can download and install that image and provide ORCA with site-specific AMI/EMI that can be used to create guest VMs on that site. Even though AMI/EMI will be different for each site, VMs will be runnning the same user-supplied image.  
     5!ImageProxy allows  independent Ecalyptus sites to create VMs with identical images. Images are identified by a URL and a GUID, representing image hash. A metadata file containing information about the different types of images needs to be created.

     27The metadata file itself is also identified by a URL and a GUID, representing metadata file hash. Provided with the URL and GUID for the metadata file, !ImageProxy associated with a Eucalyptus site can download and install the required images and provide ORCA with site-specific image ids (AMI/EMI, AKI/EKI, ARI/ERI) that can be used to create guest VMs on that site. Even though image ids will be different for each site, VMs will be runnning the same user-supplied image.
