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?[edit]

Today's installment of Fedora Test Day will focus on Virtualization in Fedora 20. Test cases will basic virtualization workflow, some cool functionality, as well as new features introduced in Fedora 20.

Who's available[edit]

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

Cole Robinson (crobinso)
Eric Blake (eblake on IRC)
Kashyap Chamarthy (kashyap on IRC)
Alexander Todorov (atodorov on IRC)

Known issues[edit]

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

libvirt managed save occasionally fails with 'unexpected migration status in setup': https://bugzilla.redhat.com/show_bug.cgi?id=1015636
virt-manager doesn't correctly report 'current' VM CPUs: https://bugzilla.redhat.com/show_bug.cgi?id=1016318
Selinux denial on the host when enabling multiqueue nic in the guest: https://bugzilla.redhat.com/show_bug.cgi?id=1016326
'groupinstall virtualization' needs additional 'yum install libvirt-daemon-config-network': https://bugzilla.redhat.com/show_bug.cgi?id=1016606
virt-manager fails creating /root/.cache/virt-manager, if you hit issues create that director manually: https://bugzilla.redhat.com/show_bug.cgi?id=1016435
libvirt generates conflicting pci address when adding qxl device: https://bugzilla.redhat.com/show_bug.cgi?id=1016775

What's needed to test[edit]

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:

Virt Test Day Live CD[edit]

There's a Fedora 20 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.

Get the image: wget -c http://fedorapeople.org/groups/virt/virt-testday-2013-10-08.iso
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)
After booting the livecd, make sure to do a yum update to get all the latest packages

Fedora 20 on a physical machine[edit]

The preferred testing platform is a fully updated Fedora 20 machine. You have a few options for getting the Fedora 20 bits:

Install with CD/DVD[edit]

You can download the Fedora 20 Alpha in various formats here.

Upgrade from Fedora 19[edit]

The supported way is using 'fedup': FedUp#How_Can_I_Upgrade_My_System_with_FedUp.3F You may also find the instructions in the fedup test case useful for using fedup to upgrade to a pre-release.
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 20 in a VM with nested virtualization[edit]

Do you have a new machine with a ton of ram and storage space, running Fedora 19? Nested virt might be an option! This allows you to create KVM guests inside a Fedora 20 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 20 virt packages on Fedora 19[edit]

If you aren't ready to make the jump to Fedora 20, this is the next best thing! Run latest virt packages on Fedora 19 from the virt-preview repo:

http://fedoraproject.org/wiki/Virtualization_Preview_Repository

Areas to test[edit]

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

VM Install[edit]

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[edit]

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

New features[edit]

New or improved features in Fedora 20:

Extra tests[edit]

These tests aren't listed in the 'test results' table, but consider giving them a spin and reporting any issues on IRC or bugzilla.

OpenVZ[edit]

libguestfs and tools[edit]

You will need Fedora 20 (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[edit]

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

Long comments[edit]

↑ Encountered the issue described in this bug ("Nothing Selected" in Software Selection). The workaround mentioned solved the issue. After that, I was able to start installation but while I was creating a user the installation aborted (error populatint transaction: failure: ntfsprogs...). Could be network issue.
↑
# F20 iso image was attached to cdrom of L1 guest
1. Following command was run to create and install L2 guest
virt-install --name nest1 --ram 2048 --disk /guests/nest1.img,size=10,bus=scsi --controller=scsi,model=virtio-scsi --accelerate --location /dev/sr0
↑ PXE and network components worked fine (used virt-install --pxe...). Only issue came at the end of install when I had to force reboot the guest. This may be a result of my odd nested virt setup.
↑ After working around the first bug, I didn't manage to install via URL due to mirror problems (a needed several retries to get the initial image, later anaconda failed in the middle of install due to a missing rpm package).
↑ After installing Fedora-20-Beta-TC2-x86_64-DVD.iso, I can't see the mouse pointer on the Desktop (this VM was installed with virt-install ...--os-variant fedora20)
↑ Found out that once you open the console thru virt-manager...no matter if you close the viewer window you can't use the virsh line. You have to close virt-manager completely in order to use virsh console...
↑ It worked thru virt-manager. With "virsh console test-day-vm" I received: Connected to domain test-day-vm Escape character is ^] error: operation failed: Active console session exists for this domain This was using Fedora-20-Beta-TC2-x86_64-DVD.iso
↑ It worked thru virt-manager. With "virsh console test-day-vm" I received: Connected to domain test-day-vm Escape character is ^] error: operation failed: Active console session exists for this domain
↑ Install guest with --os-variant fedora20 and verified guest xml has serial console device and can login using virsh console and virt-manager.
↑ Launched L1 using virt-manager (CPU copy host). Verified that qemu on host has -cpu SandyBridge,+pdpe1gb,+osxsave,+dca,+pcid,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme. Inside guest, cpuinfo shows SandyBridge but no vmx flags found.
↑ Same thing as observed by atodorov. However, if I manually add the Console Device via "Add Hardware" option, I get a working console in virt-manager. 'virsh console vm-name' still doesn't work though.
↑ Error saving domain: internal error: unexpected migration status in setup Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 91, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/engine.py", line 918, in cb vm.save(path, meter=asyncjob.get_meter()) File "/usr/share/virt-manager/virtManager/domain.py", line 1309, in save self._backend.managedSave(0) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 911, in managedSave if ret == -1: raise libvirtError ('virDomainManagedSave() failed', dom=self) libvirtError: internal error: unexpected migration status in setup
↑ Finally I have been able to add a virtio console and it works fine from virt-manager. From command line I have been able to connect but login didn't appear and I haven't been able to login.
↑ My Guest didn't have a virtio console. After add it guest doesn't start and in /var/log/libvirt/qemu/fedora20.log I have: ... Warning: option deprecated, use lost_tick_policy property of kvm-pit instead. char device redirected to /dev/pts/2 (label charserial0) char device redirected to /dev/pts/3 (label charconsole1) Failed to allocate 1073741824 B: Cannot allocate memory 2013-10-09 13:33:50.918+0000: shutting down
↑ I have been able to attach USB pen-drive from my Lenovo to my first Fedora 20 VM. When I try to attach this pen-drive to my nested Fedora 20 nested VM I receive this error: Path '/dev/bus/usb/000/000' is not accessible: No such file or directory Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/addhardware.py", line 1261, in add_device self.vm.attach_device(self._dev) File "/usr/share/virt-manager/virtManager/domain.py", line 851, in attach_device self._backend.attachDevice(devxml) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 429, in attachDevice if ret == -1: raise libvirtError ('virDomainAttachDevice() failed', dom=self) libvirtError: Path '/dev/bus/usb/000/000' is not accessible: No such file or directory It says that it's possible to see the attached pen-drive in next reboot but after rebooting it's no possible to see it.
