	Plex86 x86 Virtual Machine Project (Site not responding. Last check: 2007-10-25)
		Plex86 has been rehashed/revitalized to offer a very lightweight Virtual Machine (VM) for running Linux/x86.
		Rather, guest Linux code is executed as-is in a safe VM environment managed by a VM monitor.
		Guest kernel code is executed at a less priviliged level, causing privileged operations to generate exceptions which are managed by the VM monitor.

	Plex86 Performance (Site not responding. Last check: 2007-10-25)
		Plex86 is NOT in a benchmarkable state, rather in a proof-of-concept state.
		Benchmarking plex86 at this point is rather moot, until the following restrictions/issues have been dealt with.
		Plex86 has a very small codebase, so it is very amenable to tweaking.

		Plex86 has been revitalized/rehashed to offer a very light (VM) Virtual Machine for running Linux / x86.
		Rather than implement a heavyweight VM which can run all guest (OSes) Operating Systems, the new approach is to run only Linux VMs, making the new plex86 architecture on the order of 100x more simplistic.
		Guest kernel code is executed at a less priviliged level, causing privileged operat I/Ons to generate except I/Ons which are managed by the VM monitor.

		In plex86 this is done by providing a kernel + subsystem that builds a real page table (and, I am + guessing, a shadow segment table) on the side and + ``warping'' between the guest application and the host + operating system.
		Plex86 then implements non-application + code using a variety of interpretation techniques ranging + from single-instruction interpretation to (eventually) JIT + compilation.
		Plex86 switches the entire address space, using + a small trampoline to switch back when the guest + environment faults.

	IA-32 Emulation
		In plex86, which emulates on a Linux host, paging and segmentation are handled by providing a kernel subsystem that builds a real page table (and, I am guessing, a shadow segment table) on the side and ``warping'' between the guest application and the host operating system.
		Plex86 then implements non-application code using a variety of interpretation techniques ranging from single-instruction interpretation to (eventually) JIT compilation.
		Unfortunately, the amount of code that plex86 places in the kernel to support this is considerable (including a JIT compiler), and would probably preclude assurance evaluation for EROS if we were to do that.

	Plex86 - Wikipedia, the free encyclopedia
		Plex86 is a project to create a virtual machine for the x86 architecture that runs Linux operating system.
		In the past there has been some confusion as to the main goal of Plex86 - starting out as a being basically a stripped-down version of Bochs.
		Plex86 has many attributes in common with Bochs, except that where bochs attempts to emulate almost the whole system (which takes considerably more system resources,) Plex86 only emulates the parts of the system that it absolutely has to, in order to be able to run a Linux operating system.

	Emulation, Virtualization, and More \| Linux Magazine
		Plex86, like VMWare, follows in the tradition of IBM mainframes: both Plex86 and mainframes use the capabilities of the underlying hardware to provide one or more virtual machines, where each virtual machine can run the operating system of your choice.
		However, with Plex86, you can use the raw horsepower of that new 2.4 GHz Pentium 4 to run Linux and Windows at the same time.
		The project's home page mentions that Plex86 can be used to run Linux inside the Plex86 virtual machine (with only minimal changes to build a suitable Linux kernel), and that you can combine Bochs (described next) and Plex86 to accelerate Bochs.

	BSDCon '03 — Technical Paper
		Plex86 uses a special protection mechanism of Pentium, which is also known as Protected Mode Virtual Interrupts (PVI).
		Compared with Plex86, our approach differs in that we use a language processor (the assembler preprocessor), and we rewrite machine instructions of a user-level OS statically.
		Our partial emulators are slower than Plex86 because Plex86 uses an efficient hardware mechanism called PVI, as described in Section 2.

		Plex86 is able to run several operating systems, including MSDOS, FreeDOS, Windows9x/NT, GNU/Linux, FreeBSD and NetBSD.

		These are both emulators that allow a lesser degree of virtualization on the x86 platform, which allows one to run multiple operating systems concurrently.
		Plex86, despite its promising appearance, is still very much pre-alpha and in fact lacks an installer altogether at this stage.
		For Linux users who need to be able to exchange files with others in native Microsoft formats, an emulated Windows environment seems to be the only option, at least for the moment.

		Plex86, posted 27 Sep 2002 at 16:32 UTC by zx64 » (Journeyer)
		Bochs and VMWare are two different things, if you want an x86 only x86 emulator (which is what VMWare is), there's Plex86 (by the same person as bochs).
		Plex86 is faster because it doesn't have to emulate the entire x86 (but needs some kernel patching).
