Since I wrote a paper some time ago, it would be a sin not to publish it.

Alexey, I will add your paper. Can I also cheekily add another two to your list:
  • Binary Translation. This is where the guest order code is in effect treated as a source code which is them compiled into a P&G conforming order code. This is what Qemu does. It has many parallels to straight emulation, but the performance is a lot better, say a 2-3x slow down, or in the case where the target architecture is largely the same as the source and many instructons just map 1-1 this gives typically less than a 20% slow down. This is what VMware does for Guest Ring 0 code.
  • Application Virtualisaton as in Softricity and Wine. Very similar to OS virtualisation but the abstraction layer is moved up to beneath the Application enabling you to virtualize on a per app basis.
:-)

I notice, but there is a problem
>Binary Translation

It can mean 2 things:
userspace level = slow = Qemu
-or-
kernelspace level = fast = VMware
This will require a lot more explanations on that topic of kernelspace/userspace.

In my article I point to kernelspace methods as "Full virtualization".

I don't want to get further into detail, because it is aimed at users, not developers.

I know its a bugger: to keep things simple and understandable you often end up being "economical with the truth". 8)

Broken links

@ TerryE
I found a couple of broken links in http://forums.virtualbox.org/viewforum.php?f=1
The first one is under "The Grand Daddy of Them All" and the second is under "VirtualBox Documents". I figure your pretty busy and may not be able to fix it right away, but you can't fix something you don't know is broken. :lol:
The one for the Virtual Documents IMO is probably an important one to have working. Thanks for your hard work.

Thanks, I've updated those links. The P&G paper is really a classic not quite along side Euclids Elements, Neuton's PM, Gödel's on formally undecidable propositions, but definitely a second tier all time great IMHO.

I recently finished writing a book on VirtualBox. Maybe you could put these free excerpts in the VirtualBox Documents list:
