== 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 ...

* [[User:rjones|Richard W.M. Jones]] (rwmjones)
* [[User:laine|Laine Stump]] (laine)

== 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: [https://bugzilla.redhat.com/show_bug.cgi?id=811967 bug 811967]
* saving (migrate to file) a guest using spice is crashy [https://bugzilla.redhat.com/show_bug.cgi?id=962954 bug 962954]
* /dev/vfio/vfio has wrong default permissions. [https://bugzilla.redhat.com/show_bug.cgi?id=967230 bug 967230]
* Storage migration can fail at the end of the process [https://bugzilla.redhat.com/show_bug.cgi?id=967242 bug 967242]
* Fedora 19 isn't listed as an OS option in virt-manager [https://bugzilla.redhat.com/show_bug.cgi?id=950230 bug 950230]
* VM's can hang when trying to destroy: [https://bugzilla.redhat.com/show_bug.cgi?id=961665 bug 961665]
* QXL + VNC has graphical corruption: [https://bugzilla.redhat.com/show_bug.cgi?id=948717 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: [https://bugzilla.redhat.com/show_bug.cgi?id=967836 bug 967836]
* Bad guest performance using virt-install --location install: [https://bugzilla.redhat.com/show_bug.cgi?id=967780 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 [[How_to_debug_Virtualization_problems#Is_My_Guest_Using_KVM.3F|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: <code>yum groupinstall virtualization</code>

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 <code>yum update</code> 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.

* Get the image: <code>wget -c http://fedorapeople.org/groups/qa/testday-20130528-x86_64.iso</code>
* For Live CD or USB setup instructions, see: [[FedoraLiveCD#Download_and_Create_Live_image_or_Live_USB]]
* If you have a really beefy machine, you can probably run the Live CD in a VM using nested virtualization! (see instructions below)

=== 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 [https://fedoraproject.org/get-prerelease 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 [https://dl.fedoraproject.org/pub/alt/stage/19-Beta-RC4/ here].

==== Upgrade from Fedora 18 ====

* The supported way is using 'fedup': [[FedUp#How_Can_I_Upgrade_My_System_with_FedUp.3F]] You may also find the instructions in the [[QA:Testcase_upgrade_fedup_cli_previous_desktop|fedup test case]] useful for using fedup to upgrade to a pre-release.
* [[Upgrading_Fedora_using_yum|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 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 [[#Fedora_19_virt_packages_on_Fedora_18|virt-preview instructions]] below, install a guest using one of the [[#VM_Install|install test cases]], and follow the [[[[QA:Testcase_KVM_nested_virt|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''' ==

=== '''VM Install''' ===

Record your results for these test cases in the '''[[#Test Results |Test Results]]''' section.

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!

* [[QA:Testcase Virtualization CDROM Guest Install| Guest install via CDROM]]
* [[QA:Testcase Virtualization URL Guest Install| Guest install via URL]]

=== '''Standard features'''===

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

* [[QA:Testcase Virtualization Virt Manager Lifecycle|VM Lifecycle (start, stop, save, clone, delete, ...)]]
* [[QA:Testcase_Virt_Serial_Console|VM serial console login]]
* [[QA:Testcase Virtualization Hotplug USB device to guest|Host USB device hotplug]]
* [[QA:Testcase_KVM_nested_virt|Enabling nested virtualization for a VM]]
* [[QA:Testcase Live Migration using libvirt/virsh|Live migration (steps included for doing this with a single physical host)]]
* [[QA:Testcase_Virtualization_KVM_PCI_Device_Assignment|Host PCI device assignment]]
* [[QA:Testcase_Virt_Change_CDROM_Media|Change CDROM media for running VM]]

=== '''New features and tests''' ===

Record your results for these test cases in the '''[[#Test Results|Test Results]]''' section.

* [[QA:Testcase_Virtualization_VirtioRNG| Virtio RNG (Random Number Generator)]]
* [[QA:Testcase_Live_Migration_using_libvirt/virsh#Migration_without_shared_storage| Live migration without shared storage (steps included for doing this with a single physical host)]]
* [[QA:Testcase_Virtualization_KVM_PCI_Device_Assignment#Device_assignment_with_VFIO| Host PCI device assignment using VFIO]]



== 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: <code># yum install '*guestf*'</code>

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:
* [[QA:Testcase Virtualization Live Backup|Live VM disk backup]]
* [[QA:Testcase Virtualization Guest Suspend Hibernate|VM suspend/hibernate]]
* [[QA:Testcase Virtualization Seccomp Sandboxing|VM sandboxing w/ syscall filters]]
* [[QA:Testcase Virtualization IO Throttling|VM IO throttling]]
* [[QA:Testcase Virtualization PV EOI|VM PV EOI performance optimization]]
* [[QA:Testcase Virtualization USB3 Device Passthrough|USB3 device assignment]]
* [[QA:Testcase Virtualization USB Redirection|USB Redirection]]

whole process:

Host:

physical F19 installation (XFCE spin) on my workstation, first installed as
Alpha TC5, but upgraded right before testing. Package versions:

- kernel-3.9.4-300.fc19.x86_64
- qemu-kvm-1.4.2-2.fc19.x86_64
- seabios-bin-1.7.2-1.fc19.noarch
- libvirt-1.0.5.1-1.fc19.x86_64
- virt-viewer-0.5.6-1.fc19.x86_64
- virt-manager-0.10.0-0.4.gitb68faac8.fc19.noarch

Guest: followed instructions in
<https://fedoraproject.org/wiki/QA:Testcase_Virtualization_URL_Guest_Install>,
version "16:32, 28 May 2013". The non-default parameters I used were:
- the VCPU count, I set it to 4;
- I pre-created the 8GB image file with qemu-img, format qcow2;
- RAM set to 4096 MB.

Auto-recognition in virt manager reports Fedora 18 for
<http://download.fedoraproject.org/pub/fedora/linux/development/19/x86_64/os/>.

Problem #1: pixel garbage visible even with Cirrus + VNC,
<https://bugzilla.redhat.com/show_bug.cgi?id=948717>. Maybe important: the
virt-manager / virt-viewer windows are X11-forwarded to my RHEL-6 laptop
over ssh.

Problem #2: when trying to make a screenshot about the pixel garbage, using
virt-manager's function, the file selection dialog comes up, but no file is
written.

Problem #3: when trying to make the same with virt-viewer, the results are
worse: we don't even reach the file selection dialog, and virt-viewer seems
to hang (doesn't refresh shadowed and redisplayed areas of the window).

Took a screenshot finally using "gnome-screenshot" on my RHEL-6 laptop.

Problem #4: when entering the root password, I specified "redhat". The
warning message says that the password is weak (OK so far), and that it
contains the user name in some form (which is incorrect).

Pixel garbage resurfaces in installed guest.

After reboot:

Problem #5: Clicking the Shut Down button in the virt-manager guest window
seems to suspend the guest only (the virt-manager main window says
Suspended), but it cannot be woken / restarted from either window. Powering
down the VM from the inside (using the GNOME 3 button) hangs virt-manager
with keyboard grabbed. (Restarting virt-manager works OK, and the guest is
actually shut off.)

After that, the first ISO was not unmounted in the guest, even though virt-manager implied so at the second attempt; listing the /run/media/user/CD_ROM_NAME directory corresponding to the ISO image produced IO errors, the CD_ROM_NAME directory was not removed. The "virsh change-media" reported success on the host side, but again its effect was not visible in the guest (same IO errors and the first ISO's name, as above).</ref>

Installation went fine.  The only weirdness was artifacts in the display of the banner like "I'm sorry Dave, I can't do that".  May be related to the Nvidia GT 650M graphics card + nouveau drivers on host, with the VNC code in Virtual Machine Manager.</ref>

Pausing a running guest (F19 Beta RC4 x64 with 4GB ram) worked using VMM, but had problems.  The "Run" option in VMM never became enabled in either the high level VMM overview window (in buttons toolbar), nor in the VNC console (buttons, menu structure).

Was able to work around this using virsh, where "resume 2" started the guest back up again fine.  VMM was able to use the guest fine then.

At this point I had to leave for airport.</ref>
