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 21. Test cases will basic virtualization workflow, some cool functionality, as well as new features introduced in Fedora 21.

[edit] Who's available

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

[edit] Known issues

  • Fedora 21 Workstation media is not detected as Fedora 21 by boxes/virt-manager: bug 1145264
  • SPICE auto guest resize isn't working: bug 1146175
  • Latest virt-customize/virt-builder seem to have issues setting passwords bug 1146275
  • virt-manager can lose track of guest state, think VM is running when it's actually stopped bug 1146277
  • F21 workstation livecd in a VM has no network connectivity, conflicts with host 'default' network 1146232
  • spice-vdagent: drag + drop doesn't open nautilus right away: bug 1146289
  • virt-manager: UI error when trying to hotplug USB/PCI: bug 1146297

[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 21 on a physical machine

The preferred testing platform is a fully updated Fedora 21 machine. You have a few options for getting the Fedora 21 bits:

[edit] Install with CD/DVD

You can download the Fedora 21 Alpha in various formats here.

[edit] Upgrade from Fedora 20

[edit] Run Fedora 21 in a VM with nested virtualization

Do you have a new machine with a ton of ram and storage space, running Fedora 21? Nested virt might be an option! This allows you to create KVM guests inside a Fedora 21 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 21 virt packages on Fedora 20

If you aren't ready to make the jump to Fedora 21, this is the next best thing! Run latest virt packages on Fedora 20 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 21 only recently. The recommended versions are:

  • qemu-system-x86-2.1.1-2.fc21 (same version for all qemu* packages)
  • libvirt-daemon-1.2.8-6.fc21
  • virt-manager-common-1.1.0-3.git310f6527.fc21

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

[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 21 (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!

  1. Worked with virt-install for F21 server install
  2. Worked for F21 server install

[edit] Long comments

  1. Installed F21 guest from LiveCD with mixed results. On the first attempt, virt-manager "lost contact" with qemu, so all the VMs disappeared! On the second attempt, the guest froze during installation, and the system would not respond to any keys or mouse clicks. On the third attemp the f21 guest installation succeeded.
  2. Guest installed over network correctly. However, at the very end of the install, reboot did NOT work. The guest never came back up. Attempts to start, restart, shutdown, reset, force shutdown the guest were unsuccessful. Had to shutdown the virt-manager. After the virt-manager re-start, was able to boot the guest.
  3. 1. testing on fed20 with fedora-virt-preview.repo 2. virt-install from URL from test/21-Alpha/Workstation/x86_64/os with defaults and encrypt hdd option 3. installation works fine 4. after reboot gnome shows wired connection as connected but with a '?' symbol. remote communication works. after reboot vm shows proper symbol in gnome.
  4. Detected OS type and version before copying the ISO to /var/lib/libvirt/images location. UI cannot detect the OS type and version after copying the ISO to /var/lib/libvirt/images location. Installation completed without issues. Guest (F20) is bootable after installation. When I checked the resource utilization in my host machine, Memory 2.7GiB of 7.8GiB and Swap 5.8MiB of 7.9GiB. Why is it going to swap space when I have lot of memory left in my main memory?
  5. QEMU: Checking for hardware virtualization  : PASS QEMU: Checking for device /dev/kvm  : PASS QEMU: Checking for device /dev/vhost-net  : PASS QEMU: Checking for device /dev/net/tun  : PASS LXC: Checking for Linux >= 2.6.26  : PASS I went further - created a VM and installed Fedora 20 on it. This is a use case I'd never do in real life, but it's nice to know it's there. I'd be much more likely to deploy some tiny server in LXC or Docker with a Firefox client than a full VM-inside-a-VM.
  6. I tested nested virt with `virsh` and `virt-xml` as the procedure outlined below: https://kashyapc.fedorapeople.org/virt/procedure-to-enable-nested-virt-on-intel-machines.txt
  7. Disconnecting from virt-manager while the drive is mounted in the guest gives a notice that "This will take effect after next guest shutdown."
  8. Issuing the "Shutdown" operation from the virt-manager procuded inconsistent results. On a RHEL7.0 guest, the shutdown operation worked. On a RHEL6.5 guest, the shutdown operation had no effect on the guest.
  9. When the guest is running, attempt to reboot the guest from the virt-manager failed with the following error message: "Guest agent not responding..."
  10. Interface suggestion; Inactivate "play" icon when in snapshot GUI. Not clear how to run/delete snapshot (right click). Perhaps a hover tooltip or run:delete icons in toolbar tied to highlighted snapshot
  11. Non RPM virtual OS running XFCE. Autoresolution fail. USB use OK. Drag file from host to virtual placed on desktop (~/Desktop). Should command listed on page be piped to grep? -> ps axwww | spice-vdagent
  12. USB Redirection: fine. Auto Resize: Fine with RHEL6 guest as indicated. Copy/Paste: fine. Drag+Drop: works, but doesn't launch nautilus on first try (bug 1146289)
  13. Worked from UI and command line. On --eject, sometimes needs to be passed twice, might see an error about tray being locked. Also, the virsh responses are incoherent, someone should file a bug about that...
  14. Wasn't smart enough to use GUI. virt-install worked and booted into the host terminal where virt-install executed. Did config including root and another user. Booted to login but WAS NOT able to successfully enter password for either created user or root (hidden chars?). Hard to believe I screwed up passwords twice (however...)
