Probably not the best list for this question but anyway...

* "snapshot" as it is done with 'savevm' from qemu monitor saves disk,
  cpu, memory state of running VM... but

  1. it must be qcow2 image
  2. it pauses the VM for couple of seconds

  is this right?

* snapshots is only for block devices, are done offline

* live snapshot is only for block devices, can be done online

* snapshot tree with branches is not supported now

  am I right?

So my understanding there is no way to have a "photo", in qemu language
_checkpoint_, in VMWare language _snapshot_ without interupting the VM.
Am I right? Any comments?

This topic is quite confusing while searching Internet.
