Fedora virt status May 2013

by Cole Robinson

Hey all, here are some notes on Fedora virt happenings for May. Fedora 19 ========= Fedora 19 beta was released right on time this past Tuesday. If you haven't updated yet, now's a good time! https://fedoraproject.org/wiki/F19_Beta_release_announcement Here's the schedule going forward: - Jun 18: Final change deadline - Jul 02: GA release So by this time next month F19 should be wrapped and waiting to be shipped :) Fedora virt test days ===================== Also on Tuesday we ran the F19 virt test day, and just yesterday was a Spice specific test day. If you missed the dates but still want to help out, give the test cases a spin and reports your results as instructed on landing page: https://fedoraproject.org/wiki/Test_Day:2013-05-28_Virtualization https://fedoraproject.org/wiki/Test_Day:2013-05-30_Spice All in all they were pretty successful: I counted 19 related bugs filed by the end of Tuesday, and quite a few more from the Spice test day. And thankfully nothing too major was found :) QEMU 1.5 ======== On Monday May 20th, QEMU 1.5 was released! Highlights from the changelog: * KVM for ARM support * A native GTK+ UI with internationalization support * Experimental VFIO support for VGA passthrough * Support for VMware PVSCSI and VMXNET3 device emulation * CPU hot-add support See the full human-readable changelog at: http://wiki.qemu.org/ChangeLog/1.5 QEMU 1.5 is currently available in rawhide and virt-preview repo for F18 and F19. For the time being we are sticking with QEMU 1.4 in Fedora 19 though. Libvirt 1.0.5 ============= On Thursday May 2nd, Libvirt 1.0.5 was released! Highlights from the changelog: * add support for NVRAM device * Add XML config for resource partitions * Add support for TPM * NPIV storage migration support This is the version we will be sticking with for F19. Libguestfs 1.22 =============== And yet another major release this month: libguestfs 1.22 came out on May 24th. The big changes: * access remote disk images over nbd, ssh, http, ftp, iscsi, ceph, and more * syslinux and extlinux bootloader support * full support for btrfs guests * large performance improvements in virt-df and virt-alignment-scan tools * new bash completions for tools Check out the full release notes here: http://libguestfs.org/guestfs-release-notes.1.html Bug stats ========= Bug count on Apr 29 2013 : 260 Total bugs today : 307 Quite a large jump this month, not unexpected given the test days and F19 beta freeze holding up some ON_QA bugs from hitting stable. But we are also do for some house cleaning. By release: * Fedora 17 : 75 * Fedora 18 : 128 * Fedora 19 : 83 * Fedora rawhide : 21 By package: * bochs : 1 * gnome-boxes : 39 * gtk-vnc : 1 * ipxe : 4 * libcacard : 1 * libguestfs : 8 * libosinfo : 7 * libseccomp : 1 * libvirt : 59 * libvirt-cim : 2 * libvirt-glib : 2 * libvirt-qmf : 1 * libvirt-sandbox : 18 * netcf : 7 * qemu : 55 * seabios : 1 * spice-gtk : 4 * spice-vdagent : 2 * usbredir : 1 * vgabios : 1 * virt-dmesg : 2 * virt-manager : 36 * virt-top : 1 * virt-v2v : 5 * virt-viewer : 7 * virt-what : 2 * virtio-win : 5 * xen : 7 * xorg-x11-drv-cirrus: 5 * xorg-x11-drv-qxl : 22 Thanks, Cole

AMD-Vi: Disabling interrupt remapping due to BIOS Bug(s) and Fedora 19 Virt Test Day (VFIO) question

by Reartes Guillermo

Hi, Since some time i get: [ 0.119059] [Firmware Bug]: AMD-Vi: IOAPIC[7] not in IVRS table [ 0.119102] [Firmware Bug]: AMD-Vi: IOAPIC[8] not in IVRS table [ 0.119143] [Firmware Bug]: AMD-Vi: No southbridge IOAPIC found in IVRS table [ 0.119184] AMD-Vi: Disabling interrupt remapping due to BIOS Bug(s) [ 1.928705] AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40 [ 1.928923] AMD-Vi: Initialized for Passthrough Mode Does these messages impede "Device assignment with VFIO" testing? My mobo is a Asus Sabertooth 990FX 1.0, there is some discussion on the forum: http://vip.asus.com/forum/view.aspx?id=20130227151715143&board_id=1&model... I tried to assign a pcie Ethernet card about a year ago (no vfio) and the result was a lockup. I have not tried ever since. Cheers.

Access from host to guest via bridge macvtap device not work.

by Dario Lesca

I have install virt-manager, libvirtd and other package on my notebook F18. Then I have setup a guest (Fedora 19 beta) and configure networking to bridge via p6p1-macvtap device. All work fine, from guest I can connect to Internet and other machine of my network, but I do not connect to host, on which run, and from host, I can't connect to guest F19. It's possible to resolve this issue? How to? Many thanks -- Dario Lesca - sip:dario@solinos.it (Inviato dal mio Linux Fedora18+Gnome3)

Fedora 19 Virt Test Day is Tuesday May 28!

by Cole Robinson

Hey all, The Fedora 19 Virt Test Day is this coming Tuesday, May 28th. Check out the test day landing page: https://fedoraproject.org/wiki/Test_Day:2013-05-28_Virtualization If you're interested in trying out some new virt functionality, there's step by step instructions for: * Live migrate a VM without the need for shared storage * Virtio RNG, a paravirtual random number generator for VMs * PCI device assignment using VFIO Even if you aren't interested in testing new features, we still need you! The test day is the perfect time to make sure your virt workflow is working fine on Fedora 19, as there will be several developers on hand to answer any questions, help with debugging, provide patches, etc. No requirement to run through test cases on the wiki, just show up and let us know what works (or breaks). And while it is preferred that you have a physical machine running Fedora 19, participating in the test day does NOT require it: you can test the latest virt bits on Fedora 17 courtesy of the virt-preview repo. For more details, as well as easy instructions on updating to Fedora 19, see: https://fedoraproject.org/wiki/Test_Day:2013-05-28_Virtualization#What.27... If you can't make the date of the test day, adding test case results to the wiki anytime next week is fine as well. Though if you do plan on showing up to the test day, add your name to the participant list on the wiki, and when the day arrives, pop into #fedora-test-day on freenode and give us a shout! Thanks, Cole

Testing Gluster 3.4.Beta

by Andrew Niemantsverdriet

Hi All, I am trying to test the VM storage in the new Gluster 3.4 Beta. I have enabled the virt-preview repo on Fedora 18 x86_64. When I go to create the image using 'qemu-img create gluster://f18-test1:0/vmstore/test1', I get an error stating: qemu-img: Unknown protocol I am guessing that the version supplied in the virt-repo does not have the --enable-glusterfs flag supplied at compile time. Are the src rpm's available for this repo some place so I could add the glusterfs flag? Or can I file a bug some place to have that feature enabled? Thanks, -- _ /-\ ndrew Niemantsverdriet Linux System Administrator Academic Computing (406) 238-7360 Rocky Mountain College 1511 Poly Dr. Billings MT, 59102

F19: replacing chardev patches with upstream ones

by Amit Shah

Hello, Fedora has carried flow control patches for qemu chardevs since a very long time now. They weren't upstream, and they were required for spice, usb-redir to work properly and not freeze the guest. Upstream qemu has now merged an alternative implementation of the same concept, and most of the bugs have been shaken out upstream (we don't know of any known bugs now). So I'm of the view we should replace the older patches in F19's qemu with the backport of the newer, upstream ones. Is this fine? I can work with Cole / Hans who have been keeping the older patches uptodate on Fedora to replace the patches. Thanks, Amit
