Using Grub 2 as a bootloader for Xen PV guests

Background: Introduction to Xen PV Bootloaders

In the very early days of Xen it was necessary for the host (domain 0)
administrator to explicitly supply a kernel (and perhaps initial
ramdisk) from the domain 0 filesystem in order to start a new guest.

This mostly worked and for some use cases, i.e. those where the host

that the host administrator needed to be involved in what many
considered to be a guest administrator, or even distribution level,

Xen Hypervisor Case Studies

I am starting a new community initiative to collect and write Xen hypervisor case studies to demonstrate the variety of ways that the Xen hypervisor is leveraged in the IT world. The initial case study is from a Swedish company, ATG: ATG Case Study Feb 29, 2008

I have created a new section in the Wiki to store all the case studies that the community or I create. You can get to the Wiki case study section here.  Please feel free to create your own case study and upload into the Wiki site or contact me at stephen.spector@citrix.com if you would like my assistance. Having an updated collection of case studies is a great way for the community to show the power and capabilities of the Xen hypervisor.
