Is it that if you take a snapshot of a running domain with memory=no, and then later resume it, it is as if the guest had crashed at the time of the snapshot ? (How does this interact with disk IO barriers?) I think the semantics should be spelled out somewhere. (Also I assume that a memory snapshot isn't available unless there's a running domain, but that also needs to be specified.)
