I see a lot of different posts related to hibernation/pause of the guest VM... So I open this new topic. I'm just a newBee who is using 4 a couple of mounths Virtual Box and I've always been hit by this: It's MUCH MUCH easier to pause/hibernate/suspend, whatsoever the GUES OS and resume later, especially on laptops while traveling. SO:

WHY can't this be done? I'm not as good in programing (fact - i'm not good at all) but can't be the memory of guest written in a file and later read by Virtual Box and make the necessaries translations of memory map so that the guest feel like resuming without knowing of anything being happened (not knowing that the free/spare physical memory locations has changed in host, but not in guest) ??

Thx. I wait for some kind of answers... Not found enough on user manual... and time 4 reading the whole forum who doesn't have a topic on this issue is hard. Timeless, like everyone who's doing 2 many different things... And by the way, Virtual Box is exactly what I was looking 4... trying different thngs, OSs, etcs.... So I believe a topic on this issue is necessary. See U later, aligator! :)

What makes you think hibernation can't be done? In fact it can and is done.

The only problem with the feature is that people forget that the VM is only suspended, not properly shut down, which is a problem if they delete media, change VM hardware recipe, move to a different host (with different CPU) etc, or update the VirtualBox software. Probably lots of other subtle effects too, such as being more affected by memory leaks and other instabilities. Easier or not, I prefer to shut down my VMs to avoid these problems.

The problems btw have nothing to do with running the OS in a VM. I always fully shut down my physical PCs for similar reasons.
