A typical virtualization system on both x86 and ARM includes three major parts:

• CPU virtualization
• Memory virtualization, and
• I/O virtualization (device, interrupt virtualization).

Because the 3rd one above normally requires additional platform/chipset support, in this article I’m going to only talk about the first two virtualization extensions that are related only to processor architectures. I will back to the 3rd one later as another topic especially for device I/O virtualization and emulation.

Update:
I found there is very very good lecture about ARM Virtualization Technology from National Tsing Hua University, the link is here:
