This is super cool. I would like to know more about VM hibernation!
Happy to chat about tech sometime, I think you folks are using firecracker for a similar use-case? Drop me a line at colin@layerci.com
I know layerci's tech precedes snapshot support in Firecracker [0], but are snapshots similar to layerci's magic or there's still a significant way for snapshots to go before it can be on par with layerci's tech? I ask because I remember you mention layerci uses techniques (from how Linux hibernates PCs) which are good enough for tests and staging but not production; [1] whereas Firecracker obviously can't rely on such tech so there must be key differences? Thanks.

We don't do much with snapshot/restore but we do a _lot_ with device mapper. It's pretty badass.
