[Fedora-xen] Questions about virtualization and Xen

[Filipe Miranda]

Hello everybody,

I would like to clear a few questions that I have about virtualization,
please correct me if I'm wrong...

1) Xen is a virtual machine monitor that uses the hardware virtualization
approach knows as para-virtualization.

2) Para-virtualization is a technology that provides the  virtual machine
monitor access directly to the machine's hardware without having  an
underlying operation system to manage that, so less layer of abstraction are
between the virtual machines OS guest and the true hardware.

3) Xen 3.0 makes possible to guests virtual machines to access the machine's
hardware either through Xens APIs or through hardware enabled virtualization
like Intel VT-x or AMD Pacifica technologies, so you can have either a
modified guest  OS like Linux or  an unmodified OS guest like Windows2003
running on top of Xen 3.0.

Are those thoughts okay?
