Paravirtualised guests are adapted by developers in order to take advantage of Xen features. In the case of Linux, folks at Cambridge University and XenSource wrote most of the code to do this. Linux distributions leverage this code in order to make their own products Xen-aware. When you install a guest using Yast, the Yast Xen module ensures that a Xen-aware kernel is installed into the virtual machine. > 2) I am using suse 10.2.

The new boot menu option starts the Xen hypervisor (which is the first code to run at boot time), which in turn starts the Linux kernel for "domain 0". Domain 0 uses a paravirtualised Linux kernel which is responsible for controlling Xen, managing other domains, providing virtual devices, etc. > I am new to Xen. So curious about knowing this. Hope that helps! Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals! Mark: To answer a question with a question: What use is a skateboard? Dave: Skateboards have wheels. Mark: My wheel has a wheel! _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
