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 [on Fedocal] and see if a similar but more recent Test Day is planned or has already happened.

[edit] What to test?

Today's installment of Fedora Test Day will focus on Virtualization in Fedora 22. Test cases will basic virtualization workflow, some cool functionality, as well as new features introduced in Fedora 22.

[edit] Who's available

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

[edit] Known issues

[edit] 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:

[edit] Fedora 22 on a physical machine

The preferred testing platform is a fully updated Fedora 22 machine. You have a few options for getting the Fedora 22 bits:

[edit] Install with CD/DVD

You can download the latest Fedora 22 Beta composes here:

[edit] Upgrade from Fedora 21

[edit] Run Fedora 22 in a VM with nested virtualization

Do you have a new machine with a ton of ram and storage space, running Fedora 22? Nested virt might be an option! This allows you to create KVM guests inside a Fedora 22 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.

[edit] Fedora 22 virt packages on Fedora 21

If you aren't ready to make the jump to Fedora 22, this is the next best thing! Run latest virt packages on Fedora 21 from the virt-preview repo:

http://fedoraproject.org/wiki/Virtualization_Preview_Repository

[edit] Areas to test

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

[edit] Ensure you are using the latest virt packages!

Several updated packages were pushed to Fedora 22 only recently. The recommended versions are:

  • qemu-system-x86-2.3.0-0.3.rc2.fc22.x86_64 (same version for all qemu* packages)
  • libvirt-daemon-1.2.13-2.fc22.x86_64
  • virt-manager-1.1.0-7.git6dbe19bd8.fc22

If a 'yum update' isn't pulling these packages in, try 'sudo yum clean all', then 'sudo yum update'.

[edit] 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!

[edit] Standard features

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

[edit] New features

These are 'newish'. We had them here last year but things have been improved quite a bit.

[edit] 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.

[edit] libguestfs and tools

You will need Fedora 22 (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

[edit] Previous test cases

Some test cases used in previous test days. Still useful to test for regressions!

Fedora 20 features:

  3. Test virt-manager and virt-install for all install methods. Tested with beta RC1 media, not RC2 on the wiki but hopefully it doesn't matter. There's a couple minor issues with the os listings, see the bugs.
  4. Tested virt-manager and virt-install.

  1. Installation of Debian 8.0 with virt-manager was successful.
  2. Deleting the VM without deleting the disk image and then importing the disk image worked correctly as well.

  1. I had mixed success. I was using virt-manager (except to set host-passthrough at level 0).

    Creating a nested guest, I got "No virtual networks available". But, the network in the L1 host was working. I used it to download the iso.

    Creating a nested guest, I got a strange error, "Unable to complete install: 'list.remove(x): x not in list'. I was trying to create the VM with a virtio-scsi disk. When I switched to virtio-blk, it worked. I'm not sure if I can reproduce this.

  2. Nested virt worked well. I used host-passthrough at L0 on Fedora 21 and SandyBridge at L1 using Fedora 22. I did everything with virt-manager using the Fedora 22 beta workstation iso. Except I used virsh edit to set host-passthrough for the L0 host. In the L1 host, I ran yum update to make sure I had qemu 2.3 rc3. I didn't get a default network for the L2 guest. And, I had trouble using virtio-scsi for the L2 guest.

  5. Mostly passed. Some weirdness with the auto resize feature.

  7. Worked. But 'eject' needs to be run twice. See the bug
  8. Used a usb2.0 thumbdrive for testing, and F22 Workstation VM
  9. Used intel NIC for passthrough. Only verified it appeared in lspci in the VM, didn't test it was working.
  10. Worked if using host-passthrough
  11. Used virt-install

  1. Save / Restore problem (could not reproduce)

    saved - OK

    restored - Not OK -> VM does not get mouse input, but domain was running

    immediately after it I cloned the VM, with cloned one both save/restore worked properly

    Next multiple save/restore actions were without problems

  2. Resize problem ( GNOME classic desktop ) Symptoms: The login freezes, showing the grey desktop only (reproducable multiple times), maybe it will react after some timeout, didn't wait for hours 1) Start VM with the settings View -> Scale Display -> Always with "Auto resize with VM window" unchecked! 2) Check the "Auto resize with VM window" option 3) Reboot the VM from menu: Virtual Machine -> Reboot 4) Try to login -> The login freezes, showing the grey desktop only How to revert back to normal: Uncheck the "Auto resize with VM window" and reboot

  1. Test virt-manager. URL install took a long time just to start, but it did reach the installer, but I stopped there. CDROM install made it past package install but appeared to hang at 'post install' handling.
  2. Installed with virt-manager, using URL install. Seemed to hang when I clicked 'reboot' at end of the installer but other than that it all worked fine.
