What to test?
Today's installment of Fedora Test Day will focus on Virtualization in Fedora 20. Test cases will basic virtualization workflow, some cool functionality, as well as new features introduced in Fedora 20.
- Cole Robinson (crobinso)
What's needed to test
For starters, your physical machine should have:
- Hardware virtualization support (e.g. Intel VT or AMD-V) (see Is My Guest Using KVM?).
- Up to 10-20Gb free disk space. Guest images take up a lot of space.
- Get the packages with:
yum groupinstall virtualization
As for getting the latest virt packages, you have a few options:
Fedora 20 on a physical machine
The preferred testing platform is a fully updated Fedora 20 machine. You have a few options for getting the Fedora 20 bits:
Install with CD/DVD
You can download the Fedora 20 Alpha in various formats here.
Upgrade from Fedora 19
- The supported way is using 'fedup': FedUp#How_Can_I_Upgrade_My_System_with_FedUp.3F You may also find the instructions in the fedup test case useful for using fedup to upgrade to a pre-release.
- Upgrade using 'yum': This method is not officially supported, but is very commonly used by developers. If you're a power user this is a possible option!
Run Fedora 20 in a VM with nested virtualization
Do you have a new machine with a ton of ram and storage space, running Fedora 19? Nested virt might be an option! This allows you to create KVM guests inside a Fedora 20 VM.
Fedora 20 virt packages on Fedora 19
If you aren't ready to make the jump to Fedora 20, this is the next best thing! Run latest virt packages on Fedora 19 from the virt-preview repo:
Areas to test
All these tests have an entry in the Test Results table, please record them there.
If you don't already have a VM available, run through one of these test cases. A fully functioning VM is required for every other test case!
These are recurring tests of standard virt features, they ensure nothing obvious is broken.
- VM Lifecycle (start, stop, save, clone, delete, ...)
- VM serial console login
- Host USB device hotplug
- Enabling nested virtualization for a VM
- Live migration (steps included for doing this with a single physical host)
- Host PCI device assignment
- Change CDROM media for running VM
Test cases forthcoming...
These tests aren't listed in the 'test results' table, but consider giving them a spin and reporting any issues on IRC or bugzilla.
libguestfs and tools
You will need Fedora 20 (host) and at least one guest (but the more the merrier).
# yum install '*guestf*'
and run through the tests here: http://libguestfs.org/guestfs-testing.1.html
Previous test cases
Some test cases used in previous test days. Still useful to test for regressions!
Fedora 19 features:
- Virtio RNG (Random Number Generator)
- Live migration without shared storage (steps included for doing this with a single physical host)
- Host PCI device assignment using VFIO
Fedora 18 features:
- Live VM disk backup
- VM suspend/hibernate
- VM sandboxing w/ syscall filters
- VM IO throttling
- VM PV EOI performance optimization
- USB3 device assignment

We will be tracking results in a web application, details forthcoming
