Running Xen
In this chapter we will take our first step towards using Xen??”installing and then
running it. In this chapter we will use Fedora Core 6 as the host operating system;
we have chosen Fedora Core 6 as it has good support for Xen. We will first add Xen
support to it so that it can be a Xen Domain0 system. In the next chapter we will
create guest domains on Fedora Core 6 that run different operating systems. We will
assume you have a stock Fedora Core 6 installed and that you are ready to convert it
to a Xen. Please make sure you can boot into it without any problems or errors. You
can either run Xwindow or work from the console. If you have not installed Fedora
Core before and need help with its configuration, the following links could be useful:
