     3== Overview == 
     4 
     5ImageProxy 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.
