This chapter of Xen Virtualization Essentials will cover in detail the ways necessary to set up and run Windows Server 2008 as a virtualized Xen guest.
Given that Windows Server 2008 falls to the Xen category of an unmodified working method (quite simply an running strategy which has not been altered specially to run about the Xen hypervisor) paravirtualization shouldn't be an option. The best way, subsequently, to virtualize Windows Server 2008 working with Xen would be to configure it as a Hardware Virtual Device (HVM) visitor. For material in regards to the differences in between paravirtualization, hardware virtualization and total virtualization browse the chapter entitled An Overview of Virtualization Procedures.

[edit] Needs for Xen Windows Server 2008 Virtualization This chapter assumes the Xen host method is operating a Xen enabled kernel and that the common Xen equipment (particularly xm) are also put in. Also, hardware virtualization requires that the host procedure hardware involve possibly Intel-VT or AMD-V virtualization support. As a way to confirm this run the following commands on the host program:
For Intel CPUs:
grep vmx /proc/cpuinfo For AMD CPUSs:
grep svm /proc/cpuinfo If neither from the above commands deliver output then it's possible these functions are unavailable and that your hardware is unable to run Xen HVM friends. It really is also likely that the host CPU supports certainly one of these qualities,microsoft office 2010 Home And Student serial key, but that the performance is disabled by default in the process BIOS. To confirm this, entry the host system’s BIOS configuration menu throughout the boot approach and glimpse for a choice related to virtualization support. If these kinds of an alternative exists and is also disabled, allow it, boot the method and repeat the previously mentioned commands.
[edit] Windows Server 2008 Installation Media So that you can install Windows Server 2008 as a Xen HVM guest the next requirement may be the operating process installation media. That is prone to be inside the form of the DVD. Set up may perhaps be done immediately in the DVD, or the contents for the DVD can be copied to an ISO picture file around the host strategy.
To make an ISO picture merely insert the DVD into a drive,office 2007 Pro Plus activation key, unmount it if it automounts and then run the following command (substituting /dev/cdrom for ones DVD drive equipment):
dd if=/dev/cdrom of=windows2008.iso [edit] Planning Storage Space for Windows Server 2008 Undoubtedly, the Windows Server 2008 guest model will have to have disk space into which it might install alone and subsequently execute. This area can consider the form of either a bodily disk drive linked on the host procedure or a disk picture file. If a physical disk drive is obtainable for your visitor make a notice of your system title. This is ordinarily a system beginning with /dev/sd or /dev/hd followed by a letter (one example is /dev/sdc or /dev/hdb).
If a disk picture is expected a single may be generated applying the dd command-line device:
dd if=/dev/zero of=xenwin2008.img bs=1024k seek=10000 count=0 The above command creates a 6Gb picture file named xenwin2008.img.
[edit] Producing the Xen Windows Server 2008 Configuration File The next stage calls for the development of a domainU configuration file ideal for setting up Windows Server 2008 as a Xen guest.
The subsequent file is definitely an instance configuration file together with the minimal settings expected to get a Windows Server 2008 Xen visitor:
import os, re
arch = os.uname()[4]
if re.search('64',office 2010 x86, arch): arch_libdir = 'lib64'
else: arch_libdir = 'lib' kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 1024 # Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
shadow_memory = 8
title = "xenwin2008"
vif = [ 'type=ioemu, bridge=xenbr0' ]
acpi = 1
apic = 1
disk = [ 'file:/home/xen/xenwin2008.img,hda,w', 'file:/home/xen/windows2008.iso,microsoft office Professional 2010 key,hdc:cdrom,r' ] device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm' #-----------------------------------------------------------------------------
# boot on floppy (a),office 2007 Pro product key, hard disk (c) or CD-ROM (d) # default: hard disk, cd-rom, floppy
boot="dc"
sdl=0
vnc=1
vncconsole=1
vncpasswd='' serial='pty'
usbdevice='tablet' The above example assumes that Windows Server 2008 is going for being installed right into a disk picture and the installation media is definitely an ISO image file. If, on the other hand, a physical disk is always to be used the disk directive might appear as follows (where /dev/sdb is replaced with the appropriate bodily gadget name):
disk = [ 'phy:/dev/sdb,hda,w', 'file:/home/xen/windows2008.iso,hdc:cdrom,r' ] Similarly, the disk = directive can be modified to perform the set up from a physical DVD drive as from the following example (where /dev/cdrom is modified to reflect the physical equipment on your host procedure):
disk = [ 'phy:/dev/sdb,hda,w', 'phy:/dev/cdrom,hdc:cdrom.r' ] The over line maps bodily disk drive /dev/sdb about the host to /dev/hda about the visitor and /dev/cdrom around the host as the CD/DVD equipment about the guest (notice that the CD/DVD gadget title on your host might possibly be different depending on your Linux distribution).
Alternatively, if a disk image file is always to be used as the disk drive the line might instead examine:
disk = [ 'file:/home/xen/xenwin2008.img,hda,w', 'phy:/dev/cdrom,hdc:cdrom,r' ] A number of the configuration settings shown inside over instance are to permit a graphical console for our Windows Server 2008 visitor running method. Xen provides a choice of VNC or SDL for supporting a graphical console when the visitor is operating. One example is the subsequent settings select VNC:
vnc = one
sdl = 0 whilst the subsequent selects SDL:
vnc = 0
sdl = one Both SDL and VNC work very well in terms of displaying Windows in a graphical console, although VNC has some distinct advantages over SDL. Firstly, VNC provides greater flexibility than SDL in terms of remote entry to your domainU graphical console. With VNC it can be plausible to connect to the graphical console from other systems, both on the local network or even over the internet. Secondly, when you close a VNC viewer window the guest domain continues to run allowing you to plainly reconnect to carry on where you left off. Closing an SDL window, however, immediately terminates the visitor domainU program resulting in attainable data loss.
By default Xen does not automatically start the VNC console when the domainU visitor starts up. So as to have the graphical console spawned automatically, the vncconsole = one setting is included.
vncconsole=1 A number of other configuration options are readily available to modify the guest environment but the previously mentioned settings are the minimal settings recommended to run a Windows guest with Xen. Once the configuration file is complete save it as xenwin2008.cfg.
[edit] Starting the Xen Windows Server 2008 HVM Guest Using the configuration complete the next stage is to start up the Xen visitor environment:
xm design xenwin2008.cfg
Utilizing config file "./xenwin2008.cfg".
Started domain xenwin2008 After a few seconds the VNC or SDL console (depending on the configuration settings) will appear and the Windows installation procedure will begin. The following figure shows the Windows Server 2008 set up operating in a VNC window:

The subsequent figure shows an set up Windows Server 2008 instance operating as being a Xen HVM visitor:
