What to test?

Today's instalment of Fedora Test Day will focus on Virtualization improvements in Fedora 12. There is a large list of virtualization improvements coming in Fedora. To simplify things, testing will be divided up into a number of sections.

If you come to this page after the test day is completed, your testing is still valuable, and you can use the information on this page to test and provide feedback.

General Virt

• PXE booting
• Live Migration
• The qcow2 image format

KVM

• KSM
• Huge page backed memory
• NIC hotplug
• Stable guest ABI

libvirt

• Storage management support
• Network interface management
• Features/VirtTCK
• Features/VirtPrivileges

libguestfs, guestfish

Read more about this here: Features/libguestfs

• libguestfs tests to try

Hardware Enablement

• SR-IOV
• VT-d

As Xen Guest (DomU)

• Xen DomU

What's needed to test

• A fully updated Fedora 12 Rawhide machine. See instructions below.
• Hardware virtualization support (e.g. Intel VT or AMD-V). If unavailable, you can still help with testing QEMU support.
• At least one guest image installed before the test day (suggested reading - Virtualization_Quick_Start)
• Up to 10-20Gb free disk space. Guest images take up a lot of space.
• See the individual test area pages for specific requirements.

Prepare your system

Testing requires the latest virtualization software included in Fedora Rawhide. Update your system to the latest rawhide using one of the following techniques.

• Install from a nearby rawhide mirror
• Download and install Custom Test Day Live Image
• Download and install Fedora 12 Alpha

Note: if you are using the Live CD image, you will need to mount storage for guests either from the local disk or from NFS. If the latter, you will need to run setsebool virt_use_nfs=on in order for it to work with SELinux.
