KVM

Virtualization With KVM On A Debian Squeeze Server
Прекрасная статья (howto) для быстрого старта по теме.
Предполагается, что у вас есть железка-сервер с аппаратной поддержкой виртуализации (для проверки выполните: # egrep '(vmx|svm)' --color=always /proc/cpuinfo) и еще одна железка в качестве раб.станции, чтобы общаться с консолями гостевых машин.

This guide explains how you can install and use KVM for creating and running virtual machines on a Debian Squeeze server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short forKernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

First check if your CPU supports hardware virtualization - if this is the case, the command
egrep '(vmx|svm)' --color=always /proc/cpuinfo
should display something, e.g. like this:
root@server1:~# egrep '(vmx|svm)' --color=always /proc/cpuinfo
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall
 nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall
 nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch
If nothing is displayed, then your processor doesn't support hardware virtualization, and you must stop here.

А, не знаю... мне пока виртуалбокса хватает.
