In the past, The Xen project used “PyGrub” and its behave like Grub and read the standard grub file “menu.lst “ to provide the Xen Project for creating process. A good news is that the Xen Project supports Grub 2 and don't need any custom implementation of Grub (PvGrub).Via SPICE you can have a better Remote Desktop compared with VNC. Better support of Virtual Desktops Protocols (SPICE).The Hypervisor that run on real Hardware is called “Level 0” and the Hypervisor that run on Guest called “Level 1” and a guest that running via “Level 1” called “Level 2”. Nested: The Xen Nested provides Hardware Virtualization to Guests and via this ability you can run Xen Project, KVM, Hyper-V and VMware ESX inside a guest and launching your test environment.This allows your guest to run much faster and our Hypervisor can run on hardware that don't support Virtualization extension. Paravirtualization: We spoke about it and said that the Paravirtualization introduced by Xen Project.In Xen 4.4, udev replaced with a custom daemon that built top of libxl and provide a good flexibility. For example, If driver crashed or infected, then the driver can be rebooted without affecting the rest of the system. Flexibility in Driver: By default, Linux Driver domains for launch back ends for guests depend on udev and it has some problems.Xen uses Microkernel design and according to the Xen Project Wiki it just 1MB in size but have a good security.

Xen Project has tons of features, but we just consider some of the most important of them:

As we said, some companies like Citrix distribute Xen as a commercial product like “Citrix XenServer” but the range of Xen use is not limited to it and this project used in many areas like Desktop Virtualization, Server Virtualization, Cloud computing and… Don't forget, when writing this book, The Xen Project is the only type-1 hypervisor that is Open Source.

Operating systems on your server will run in parallel mode. The Xen Project Hypervisor is an Open Source “Type-1” or Bare Metal Hypervisor which let you run many OS on your server. Welcome to chapter 2! In this chapter, we will talk about Xen Project more and cover Installation Xen Project. Chapter 2 : Xen Project What is XenProject?
