Changes

If neither of the above command commands produce output then it is likely these features are unavailable and that your hardware is unable to run Xen HVM guests. It is also possible that the host CPU supports one of these features, but that the functionality is disabled by default in the system BIOS. To verify this, access the host system’s BIOS configuration menu during the boot process and look for an option related to virtualization support. If such an option exists and is disabled, enable it, boot the system and repeat the above commands.

The above example assumes that Windows Server 2008 is going to be installed into a disk image and that the installation media is an ISO image file. If, on the other hand, a physical disk is to be used the disk directive might appear as follows (where ''/dev/sdb'' is replaced with the appropriate physcial physical device name):

Similarly, the ''disk = '' directive can be modified to perform the installation from a physical DVD drive as in the following example (where ''/dev/hdccdrom'' is modified to reflect the physical device on your host system):

<pre>disk = [ 'phy:/dev/sdb,hda,w', 'phy:/dev/cdrom,hdc:cdrom.r' ]</pre> The above line maps physical disk drive ''/dev/sdb'' on the host to ''/dev/hda'' on the guest and ''/dev/hdccdrom'' on the host as the CD/DVD device on the guest (note that the CD/DVD device name on your host may be different depending on your Linux distribution).

disk = [ 'phyfile:/devhome/xen/sdbxenwin2008.img,hda,w', 'phy:/dev/hdbcdrom,hdc:cdrom,r' ]
