Totally off-topic indeed, but was an interesting discussion nonetheless I love learning about - and discussing - OS theory.

So no data belonging to an active process is ever swapped out ? Sounds strange... I'd have imagined that if pages of data have not been recently used by a given process, the operating system could consider that they are not in the working set anymore, mark the pages as absent, and swap them out in o...

Yeah, I've noticed it when I experimented with a setting that was a bit too high. It's not exactly that the VM did not start, but rather that X died when it tried to do so :) I understand why a VM would want unswapped RAM, what I don't understand is why my Linux host can't swap tasks other than VB o...

Thank you very much, I'm going to try the CLI and see how well it goes :P (I think that on a modern OS, CPU configuration tables, the memory manager, its data, and the pages of currently running code must be kept in RAM, but everything else can be swapped out. Now, of course, such a setup would run ...

Hi everyone !

I have a computer with 4Gb RAM, and I'd like to run a VM with more than 3 GB of RAM on top of it. I don't care if the host starts swapping like crazy and the performance is terrible, it's just for experimental purposes. How can I bypass the "20% of system memory" limitation ?

Hello everyone ! I guess you don't see many hobby OS developers around here... anyway, here I go. I'm developing a 64-bit kernel. It runs fine on Bochs and Qemu no matter what the underlying OS is, and it used to run fine on VirtualBox 3.0/Windows 7 x64 with VT-x enabled. My computer is an Asus N61J...
