== What to test? ==

Today's installment of Fedora Test Day will focus on [[Virtualization]] in Fedora 18. Test cases will basic virtualization workflow, some cool functionality, as well as new features introduced in Fedora 18.

== Who's available ==

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

* [[User:mrezanin|Miroslav Rezanina]] (mrezanin)
* [[User:ericb|Eric Blake]] (eblake)
* [[User:laine|Laine Stump]] (laine)

== Known issues ==

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

* Pausing a KVM guest can crash that guest. Might be specific to guests using a QXL video device (the default created by virt-manager): https://bugzilla.redhat.com/show_bug.cgi?id=870811
* 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
* qemu + libvirt + seccomp doesn't work, the qemu guests fail to even start: https://bugzilla.redhat.com/show_bug.cgi?id=855162

== 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 <br><pre>yum groupinstall virtualization</pre>

As for getting the latest virt packages, you have a few options:

=== Fedora 18 on a physical machine ===

The preferred testing platform is a fully updated Fedora 18 machine. You have a few options for getting the Fedora 18 bits:

* Install with CD/DVD.
** Latest live CD builds ('desktop' is the default): http://alt.fedoraproject.org/pub/alt/nightly-composes/
** Latest 64 Bit DVD: http://dl.fedoraproject.org/pub/alt/stage/18-Beta-TC6/Fedora/x86_64/iso/

* Upgrade from Fedora 17
** The supported way is using CD/DVD upgrade. See media links above
** Update using 'yum': https://fedoraproject.org/wiki/Upgrading_Fedora_using_yum  <br>This method is not supported, but is very commonly used by developers. If you're a power user this is a possible option!

=== Fedora 18 virt packages on Fedora 17 ===

If you aren't ready to make the jump to Fedora 18, this is the next best thing! Run latest virt packages on Fedora 17 from the virt-preview repo:

http://fedoraproject.org/wiki/Virtualization_Preview_Repository

=== Run Fedora 18 in a VM with nested virtualization ===

Do you have a new machine with a ton of ram and storage space, running Fedora 17? Nested virt might be an option!
This allows you to create KVM guests _inside_ a Fedora 18 VM.

# Install the latest virt packages from virt-preview using the instructions above.
# Install a Fedora 18 guest using one of the test cases below.
# Use virt-manager to 'copy host CPU' for your VM. Boot the VM, install virtualization packages, and verify that nested virt is working by running the following command as root: <br><pre>virt-host-validate</pre>

Some notes on nested virt with AMD and Intel:

* http://kashyapc.wordpress.com/2012/01/18/nested-virtualization-with-kvm-and-amd/
* http://kashyapc.wordpress.com/2012/01/14/nested-virtualization-with-kvm-intel/
* http://kashyapc.wordpress.com/2012/07/28/nested-virtualization-with-intel-take-2-with-fedora-17/

== 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]]

Next give this a run through, which should ensure things aren't broken in some obvious manner:

* [[QA:Testcase Virtualization Virt Manager Lifecycle|VM Lifecycle (start, stop, save, delete, ...)]]

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

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

* [[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]]

=== libguestfs and tools ===

You will need Fedora 18 (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

In Fedora 18, we are using [http://libvirt.org libvirt] to launch the appliance, and [http://selinuxproject.org/page/SVirt sVirt] + SELinux to make everything [http://libguestfs.org/guestfs.3.html#security much more secure].  Therefore it's better (though not required) if you can run these tests with SELinux set to enforcing.

=== Previous test cases ===

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

Migration:

* [[QA:Testcase Live Migration using libvirt/virsh|Live migration with virsh]]
* [[QA:Testcase Offline (paused) Migration using libvirt/virsh|Offline migration with virsh]]

Hotplug:

* [[QA:Testcase Virtualization NIC Hotplug virsh attach detach|NIC hotplug with virsh]]
* [[QA:Testcase Virtualization Attach/Detach a SCSI device to guest|SCSI hotplug with virsh]]
* [[QA:Testcase Virtualization Hotplug USB device to guest|USB hotplug with virsh]]

virtio-scsi:

* [[QA:Testcase Virtualization Virtio SCSI Install|Virtio SCSI install]]
* [[QA:Testcase Virtualization Virtio SCSI Hotplug|Virtio SCSI hotplug]]


== Test Results ==

Each tester should add a row for their results.

If you have problems with any of the tests, report a bug to [https://bugzilla.redhat.com Bugzilla]. If you have any questions about what component to file against,
just shout in the IRC channel and we can help you out. Same goes for any selinux alerts you might see!
