Don't get me wrong, I don't think this is a killer feature. But when I
initially implemented compression, I definitely would have done it through
the API if we had had a "flags" parameter available for virDomainSave(). Now
that we have a ManagedSave that does have a flags parameter, I figured we do
it the right way. I think it's a little cleaner, and more intuitive, to do
it through the API, and it makes the feature available to hypervisors other
than qemu.
Are there any other hypervisors that (currently or plan to) support
compression?
