Hi, Fedora is my favorite Linux distribution. I have been eagerly anticipating the upcoming release of Fedora 12 but am disappointed to discover that it will not support Xen pv-ops dom0 kernel. <QUOTE> <h3> Xen Kernel Support </h3> The <code>kernel</code> package in Fedora 12 supports booting as a guest domU, but will not function as a dom0 until such support is provided upstream. Work is ongoing and hopes are high that support will be included in <code>kernel</code> 2.6.33 and Fedora 13. The most recent Fedora release with dom0 support is Fedora 8. </QUOTE> Link: <a href="http://fedoraproject.org/wiki/Docs/Beats/Virtualization">http://fedoraproject.org/wiki/Docs/Beats/Virtualization</a> Here is a list of my Xen pv-ops dom0-related videos on Youtube so far. I am using Fedora 11 x86_64 as my host operating system.

Admittedly I have gained a lot of useful knowledge throughout the process. Thanks to Boris' setup guides, and assistance from Pasi, Han Weidong from Intel Corp, Jeremy Fitzhardinge from Citrix, and the rest of the Xen developers community, I have managed to get a fully working Xen pv-ops dom0 Fedora 11 host operating system. It will be a daunting task for newbie Linux users who want to setup a Xen pv-ops dom0 system with the more recent releases of Fedora. Please do consider including Xen pv-ops dom0 kernel in the next release of Fedora. Michael Young has Xen dom0 kernel RPM packages for FC12. I am surprised that they are not included in the upcoming Fedora 12 release.
