Can't make the date?
If you come to this page before or after the test day is completed, your testing is still valuable, and you can use the information on this page to test, file any bugs you find at Bugzilla, and add your results to the results section. If this page is more than a month old when you arrive here, please check the current schedule and see if a similar but more recent Test Day is planned or has already happened.

What to test?

Today's installment of Fedora Test Day will focus on Virtualization in Fedora 19. Test cases will basic virtualization workflow, some cool functionality, as well as new features introduced in Fedora 19.

Who's available

The following cast of characters will be available testing, workarounds, bug fixes, and general discussion ...

Known issues

Before you begin testing, there are a few known bugs that should be taken into account:

  • running libvirtd inside a guest can break that guests networking. you can work around this by using 'sudo virsh net-edit default' inside the VM, and change all instances of 192.168.122 to 192.168.123 and restarting the VM: bug 811967
  • saving (migrate to file) a guest using spice is crashy bug 962954
  • /dev/vfio/vfio has wrong default permissions. bug 967230
  • Storage migration can fail at the end of the process bug 967242
  • Fedora 19 isn't listed as an OS option in virt-manager bug 950230
  • VM's can hang when trying to destroy: bug 961665
  • QXL + VNC has graphical corruption: bug 948717
  • On initial install, wrong /dev/kvm permissions cause weird libvirt error reporting: hda-duplex not supported by this binary. Reboot should fix it: bug 967836
  • Bad guest performance using virt-install --location install: bug 967780

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?). If unavailable, you can still help with testing QEMU support.
  • 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:

Virt Test Day Live CD

There's a Fedora 19 live CD image that already has all the required virtualization packages installed (though you should still yum update after booting). You will probably want a good amount of RAM if using this option (greater than 4G) since you'll be using RAM for both a VM and running the live OS.

Fedora 19 on a physical machine

The preferred testing platform is a fully updated Fedora 19 machine. You have a few options for getting the Fedora 19 bits:

Install with CD/DVD

You can download the Fedora 19 Beta in various formats here. Note: the Beta will be officially released on 2013-05-28, the day of the Test Day; if you wish to download it ahead of time, the images can be found here.

Upgrade from Fedora 18

Run Fedora 19 in a VM with nested virtualization

Do you have a new machine with a ton of ram and storage space, running Fedora 18? Nested virt might be an option! This allows you to create KVM guests inside a Fedora 19 VM.

Use the virt-preview instructions below, install a guest using one of the install test cases, and follow the [[nested virt test case to finish the setup and verify things are working correctly.

Fedora 19 virt packages on Fedora 18

If you aren't ready to make the jump to Fedora 19, this is the next best thing! Run latest virt packages on Fedora 18 from the virt-preview repo:

http://fedoraproject.org/wiki/Virtualization_Preview_Repository

At present, some of the packages in virt-preview are actually newer than what's in Fedora 19 (qemu 1.4 vs. qemu 1.5), but testing is still useful.

Areas to test

All these tests have an entry in the Test Results table, please record them there.

VM Install

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!

Standard features

These are recurring tests of standard virt features, they ensure nothing obvious is broken.

New features

New or improved features in Fedora 19:


Extra tests

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 19 (host) and at least one guest (but the more the merrier).

Install libguestfs: # 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 18 features:

Test Results

We are tracking test results in a web application over here

Results from this web application will be automatically transferred to the Wiki on 2013-06-11 and the reporting system will be shutdown. Feel free to continue testing and filling the wiki even after this date.

Should you encounter any problem while using the web application, please contact jskladan on #fedora-qa channel at freenode, or send an email to jskladan@fedoraproject.org
