Simulate Hibernation / Suspend-To-Disk

[xloem]

I think this is a known idea but I didn't find an issue for it.

For laptops, hibernation is great to just close the lid and come back to your work a week later. For security, this is important because so much data is in RAM.

Xen does not support suspend-to-disk, but Qubes could emulate suspend-to-disk by hibernating all the VMs, and then simply shutting down. It would be great if this were formally supported some day.

Yes, this has come up on the mailing lists quite a lot over the years:

https://groups.google.com/forum/#!searchin/qubes-users/hibernate

My sense is that this is something that is possible but that would be a very low priority (if a priority at all) for the Qubes team. So, we'd be open to accepting patches for this, but that's probably the only way it'll happen (at least any time soon).

This would be desirable for the purposes of clearing from RAM the key used for full disk encryption.

EDIT to add: It would make sense to remove the option to hibernate from the relevant UI menus of a Qubes installation until it is supported.
