Virtualization architectures

The linux technical review presented an overview of the different type of virtualizations architectures. I recopied the table as a reminder.

From the Linux Magazine 01/2010 Linux Technical Review:

	Gleiche ISA	Verschiedene ISA
System VMs	Classic Hypervisors	System Emulators
	z.B.: Xen, VMware ESX	z.B.: Bochs, Qemu
	Hosted VMs	Co-Designed VMs
	z.B.: VMware Workstation	z.B. AS/40
Prozess VMs	Multiprogramming	Dynamic Translation
	z.B.: Linux, Windows	z.B. FX!32, Transmeta
	Binary Recoding	HLL VMs
	z.B.: Valgrind	z.B. Java VM

Lguest - simple virtualization mechanism

From the article at LWN.net, I learnt that there is a small virtualisation framework for linux using an hypervisor: lguest. This virtualization framework allows the testing of drivers. So I should use this to test some kernel changes which might be problematic.
