[...] It can in fact be a good deal more complicated than this. Depending on what hypervisor backends are in use, the image may need to be in one or more of raw, qcow2 or vhd formats (there may be more I'm not remembering). Further, the options for converting between them are not ubiquitous nor necessarily even easy to obtain/build. There is at least the option of native compression with qcow2, which works reasonably well if you ignore the CPU overhead of decompressing at boot. As you indicate, Glance's "tasks API" is a pretty terrible idea. You can automate just about anything with it, but as a result it's got whatever completely nonstandard behavior the deployer has decided to give it so a user has no hope of consistency from one environment to the next. -- Jeremy Stanley
