Yeah, concurrent is a little trickier. Simple solution is for a
management tool to just do a stop + multiple snapshots + cont. It's
equivalent to what we'd do if we don't do it aio which is probably how
we'd do the first implementation.
But in the long term, I think the most elegant solution would be to
expose the freeze api via QMP and let a management tool freeze
multiple
devices, then start taking snapshots, then unfreeze them when all
snapshots are complete.

qemu should call the freeze as part of the process (for all of the relevant devices) then take the snapshots then thaw.
Yeah, I'm not opposed to us providing simpler interfaces in addition to
or in lieu of lower level interfaces.
