The fact that tripped you up is a feature of Linux guests, not of VirtualBox or of guests in general. First of all it assumes that the guest OS uses a swap space on disk at all - and that aint necessarily so. Then, not all guests implement it the same way even when they do use the concept: e.g. Windows creates a dynamically sized swap file in the main partition, not a separate fixed partition, so with a Windows guest you would not have wondered about the disparity between partition size and disk size.kgomara wrote:perhaps others were tripped up by not understanding that the swap space nets out of the Virtual space. If I had understood that up front I would have allocated much more space initially and never had the problem.
Frankly, there is too much possible variation in guests for it to be practical to warn you about every misunderstanding you might have. You just have to learn as you go (like the rest of us!).
