What are Fedora Test Days
According to the Fedora Project's Wiki, Fedora Test Days are "an opportunity to exercise a completed, or in-development, Feature planned for an upcoming Fedora release. Each Test Day brings something unique and you're encouraged to join and share your ideas, tests, and results."
Test Days happen (typically) on IRC in the #fedora-test-day channel on Freenode.
Fedora Tests Days and Xen
It is common practice for one of the Test Days to be about Virtualization. That is why the subject is relevant to this Wiki: the Fedora Virtualization Test Day is a real good occasion to verify how Xen will work in the upcoming version of the distribution.
The Virtualization Test Day for Fedora 18 is happening on 2012-11-01
Preparing the Host
It may sound obvious, but the first thing one needs to test how Xen works on a new Alpha/Beta release of Fedora... Is an actual host machine equipped with such a release of Fedora (18 Beta TC6 at the time of writing). This section quickly goes through the various steps needed to get there.
Obtaining the Install Media
During Beta phase, a reasonable image to download for your testing can usually be found here. (Note that, in all the subsection below, the 18-Beta-TC6 part is just a placeholder; all are valid URLs at the time of writing, but it should be changed accordingly, depending on when testing happens.)
DVD or Live Images
Full DVD installer images are available here:
While LiveCD images can be fetched at this url:
in a PXEboot environment, kernel and RAMfs for the installer can be downloaded via the following commands
wget https://dl.fedoraproject.org/pub/alt/stage/18-Beta-TC6/Fedora/x86_64/os/images/pxeboot/initrd.img wget https://dl.fedoraproject.org/pub/alt/stage/18-Beta-TC6/Fedora/x86_64/os/images/pxeboot/vmlinuz
Installing the Host
Installing and Configuring Fedora
This should happen in the usual way you install Fedora. Given the very specific purpose of this installation (testing running VM with Xen on Fedora), anything you can find in the Categories Category:Host Install and Category:Host Configuration on this Wiki can be considered useful.
Also, the Fedora Host Installation (still on this Wiki) contains some more specific information about the subject, especially useful post-install Xen-related configuration tips.
yum install xen
And you're all set, the hypervisor plus all its dependencies will be installed, GRUB menu will be updated, etc.
Installing libvirt & C.
yum install libvirt-daemon-driver-xen libvirt-daemon-config-network libvirt-daemon-driver-network virt-manager python-virtinst virt-viewer libguestfs-tools-c
Going for a Live
A live CD/USB stick can be used as well. Although probably less powerful as a testing environment, it may turn out to be very convenient, in case you don't have any spare hardware handy. Instruction on how to create a Fedora live image can be found here.
Joining the Test Day
Of course, although verifying that Xen and the libvirt-related tools are well integrated and fully functional in the next Fedora release is of paramount importance, also trying out whether and how the Xen default toolstack (libxl/xl, as you'll most likely be dealing with Xen >= 4.2) works, as it happens during Test Days (like the one we had for Xen 2.4 RC2).
Pushing Out Results
Of course, be sure you report anything you find out during the Test Day to the proper places. There are some of the mailing lists you want to post your success story on, or talk about the issues you had:
- fedora-devel (email@example.com) and/or xen-devel (firstname.lastname@example.org), for things you think could be bugs that need developers' attention;
- Fedora Xen (mailto:email@example.com firstname.lastname@example.org) and/or  (email@example.com), for things you think could be related to Xen usage in general or to Xen usage/packaging/integration in Fedora;
