Good to know Blake, thanks.

IMHO you should consider this a low prio, but very nice to have item.
Without it seems like calling for trouble later on.
Cases are:
a) Like John here unable to start guests they expected to be able to
b) (more critical) people that also changed vm.overcommit_memory to allow the initial alloc breaking hard later on.

In a perfect world I'd envision a slider like this:

Overcommit ratio:
1.0 * 10
|----------|----------------|

* The recommended upper limit at (PhysMem-15%)+Swap
That way it would still be under the full control of the user, but this bug here would not grow into a common issue.

Until such code that adds something like an "upper recommended bound" is written you could just make things more clear with a comment at the slider maybe?

Therefore I'd be happy if you would consider this as a feature request.

@John - from your POV are you fine for now with the explanations or is there something else that was missed but is needed for you?
