F11 Release =========== The F11 release is imminent. Happily, there are no open bugs remaining on the virtualization blocker list. However, the blocker list for the entire distro still has a significant number of open bugs so Release Engineering has announced a one week slip of the release date: http://www.redhat.com/archives/fedora-devel-list/2009-May/msg01585.html We still have a massive list of bugs on the virt target list for F-11: https://bugzilla.redhat.com/showdependencytree.cgi?id=F11VirtTarget&hide_re… These bugs haven't been forgotten about and we hope to fix many of them in post-release updates. Please do jump in and help out! F12 Features ============ Dan Berrange has added three new feature pages for F12: http://fedoraproject.org/wiki/Features/VirtAppliances http://fedoraproject.org/wiki/Features/VirtPrivileges http://fedoraproject.org/wiki/Features/VirtTCK the full list of features is available here: http://fedoraproject.org/wiki/Category:F12_Virt_Features Many more features are planned for F12 and we should see more feature pages posted to the wiki as folks begin work on them. Is it 'Raw Virt' or 'Virt Hide'? ================================ As discussed previously on the fedora-virt list, we're going to maintain a 'virt preview' yum repository for Fedora 11 users who wish to test out the latest virtualization bits from Fedora 12: https://www.redhat.com/archives/fedora-virt/2009-May/msg00074.html This repository isn't intended to replace rawhide - e.g. if we had this repository during F-11 development, it wouldn't have helped with sVirt testing. We hope it will allow people who are interested in virtualization - but who would not consider running rawhide - to test some of the latest virtualization features. Work remains in order to ensure that this repository is as useful as possible and volunteers of help are most welcome. Virt Test Day ============= The F11 Virtualization Test Day was held on May 7th and was a great success. Over 30 people turned out and a whole heap of high quality bug reports were filed: https://www.redhat.com/archives/fedora-virt/2009-May/msg00046.html Our hope is that the test cases and wiki structure used for this test day will be re-used for similar test days for F-12 and beyond. FWN === Dale Bewley continues his excellent series of virtualization sections in Fedora Weekly News: http://fedoraproject.org/wiki/FWN/Issue175#Virtualization http://fedoraproject.org/wiki/FWN/Issue176#Virtualization http://fedoraproject.org/wiki/FWN/Issue177#Virtualization FUDCon ====== The 2009 Berlin FUDCon is coming up at the end of June: http://fedoraproject.org/wiki/FUDConBerlin2009 Rich Jones and I will be there giving a talk and we're looking forward to meeting any other Fedora virt folks who happen to be there too. http://fedoraproject.org/wiki/Rich_Jones_and_Mark_McLoughlin_-_Virtualizati… virt-inspector ============== Rich Jones announced the available of a new tool called virt-inspector: https://www.redhat.com/archives/fedora-virt/2009-May/msg00073.html This is a tool based around libguestfs which can inspect a virtual machine disk image and tell you some interesting things about what's inside it. Some of the things it can tell you: - What operating system(s) are installed, and what distros and versions. It currently covers RHEL releases, Fedora releases, Debian releases, and has limited support for Windows. - How disk partitions are expected to be mounted (eg. /dev/sda1 -> /boot) - What applications are installed. - What kernel(s) are installed. - What kernel modules are installed. It can produce output in plain text (as a report) or in XML (to feed into other programs). This is currently available for F-11 through libguestfs-1.0.27 in updates-testing: https://admin.fedoraproject.org/updates/libguestfs-1.0.27-1.fc11.1 Xen Dom0 Kernels ================ Michael Young continues building Xen Dom0 kernels: http://www.redhat.com/archives/fedora-virt/2009-May/msg00099.html http://www.redhat.com/archives/fedora-virt/2009-May/msg00051.html Upstream, Jeremy Fitzhardinge continues to slug it out with Ingo Molnar to get his patches merged for 2.6.31. Latest progress here: http://lists.xensource.com/archives/html/xen-devel/2009-05/threads.html#006… Bugs ==== Crikey! Streuth! DOOM-O-METER: 182 open bugs 3 weeks ago, 236 now. Yes, we have bugs. Lots of them! Seriously, we've had a huge surge in bugzilla activity since the test day. I've even left out most of the test day bugs below, since I have already posted details of those to the list. = New Bugs = == kvm == https://bugzilla.redhat.com/499210 OpenSolaris installer segfaults from OOM under KVM, bug not with unaccelerated QEMU Looks like some difference between KVM and TCG is causing the OpenSolaris installer to handle OOM differently. https://bugzilla.redhat.com/346151 Create a kvm user account and kvm group https://bugzilla.redhat.com/497341 Make the /dev/kvm device world accessible to all users by default https://bugzilla.redhat.com/500472 QEMU driver should run all QEMU VMs as non-root system account All bugs related to the VirtPrivileges feature for F-12. https://bugzilla.redhat.com/500866 virtio-net driver does not support ethtool drvinfo query The virtio-net driver should probably support some more ethtool queries. == qemu == https://bugzilla.redhat.com/499060 qemu-kvm with -vga std does not provide widescreen resolution in win xp guest Looks like a vgabios regression since qemu-0.9.1. Glauber pushed a rebase to a newer version from upstream, but that only seems to make matters worse. https://bugzilla.redhat.com/501545 "qemu-kvm -vga std" broken with vgabios 0.6c Details on how 0.6c makes things worse; it's been unpushed from F-11 but we've left it in F-12 for now. https://bugzilla.redhat.com/499542 qemu graphics corruption with -vga vmware Looks like -vga vmware is totally broken at the moment, that's assuming it isn't a guest driver issue. https://bugzilla.redhat.com/502058 qemu -no-kvm guest hangs at during timer setup; works with noapic https://bugzilla.redhat.com/502440 qemu -no-kvm guest oops during IO-APIC setup Looks like two possibly related APIC issue when running qemu-kvm -no-kvm. This preventing us from doing a "make check" during libguestfs build. https://bugzilla.redhat.com/501264 qemu segfaults for -net socket,listen=localhost:4567 Fixed upstream, Glauber has proposed the fix for the stable branch. https://bugzilla.redhat.com/499596 32 bit KVM guest hangs enabling NX protection; booting with -cpu qemu32 works We're pinning our hopes on the cpuid trimming patches fixing this, but it's not totally clear they will. https://bugzilla.redhat.com/501131 qemu segfault when VNC client disconnects It looks like this is an issue with the way qemu's vnc code handles I/O errrors. A hacky patch has been built for the reporter to verify that theory. https://bugzilla.redhat.com/500863 qemu -kernel/-initrd with 4Gb memory and F6 image results in "initramfs bad gzip magic" Daire Byrne, aka "-kernel man", found yet another bug with qemu-kvm -kernel. Glauber promptly fixed this upstream and it will be in the qemu-0.10.5 update we hope to push next week. https://bugzilla.redhat.com/501935 qemu-kvm -kernel should parse "vga=" cmdline option Daire also discovered an oddity whereby vga= option is ignored if you boot with -kernel. It turns out the bootloader implements this option and, so, qemu should implement it too. https://bugzilla.redhat.com/500317 Vista install fails in qemu guest (without kvm) == libvirt == https://bugzilla.redhat.com/499223 Add virt-install --virt-type option and make kvm the default In F-12, the plan is to no longer require --accelerate to be specified in order to use kvm. https://bugzilla.redhat.com/499970 F12: port libvirt to PolicyKit 1.0 Repeat after me: "We loves ABI changes". https://bugzilla.redhat.com/501934 libvirt bridge should not have IPv6 disabled https://bugzilla.redhat.com/499669 libvirt QEMU driver is using old pci_add/pci_del syntax PCI hotplug isn't currently working because qemu-kvm's monitor command syntax has changed and hasn't been updated to use that syntax. https://bugzilla.redhat.com/501550 virtio console device has lame PCI class info ajax reports that virtio-console's PCI class is bogus and proposes a patch to fix it. The patch has now been posted upstream. https://bugzilla.redhat.com/501328 Add support for virtio console in libvirt QEMU driver https://bugzilla.redhat.com/501720 upstart does not launch a login process on /dev/hvc0 in all cases The plan here is to enable virtio console for Linux guests by default and have them unconditionally configure it as a console. This will give us an "always available" console like we have for Xen. == virtinst == https://bugzilla.redhat.com/500320 Vista needs >15G; add "minimum disk size" to python-virtinst OS_TYPES table? https://bugzilla.redhat.com/502088 virt-clone.log does not get closed on exec == virt-manager == https://bugzilla.redhat.com/499812 host screensaver kicks in while virt-manager guest console is grabbed Dan reckons this is a problem for gnome-screensaver, but most likely this is just a fundamental limitation of X grabs and virt-manager will have to explicitly inhibit the screensaver. https://bugzilla.redhat.com/501922 virt-manager: NFS install of guest complains about insufficient privilege Another side effect of us not running virt-manager as root by default anymore. We should be able to use libvirt's storage management APIs to fix this. https://bugzilla.redhat.com/500940 virt-manager should delete failed guest images https://bugzilla.redhat.com/502204 virt-manager's dialog to connect an existing CD-ROM to an ISO does not use storage pool interface https://bugzilla.redhat.com/502333 virt-manager should show guest disk size in Details == libguestfs == https://bugzilla.redhat.com/501878 guestfish built-in commands like 'alloc' and 'help' don't autocomplete https://bugzilla.redhat.com/501882 /tmp/libguestfs temporary directory is not cleaned up https://bugzilla.redhat.com/501883 javadoc messed up in libguestfs java documentation https://bugzilla.redhat.com/502074 libguestfs checksum test (of SHA1) fails on i586 (running under qemu sans kvm) https://bugzilla.redhat.com/502309 libguestfs build failure - tests occasionally fail with 'ranlib: './libmlguestfs.a': No such file' Rich moved his libguestfs TODO list to bugzilla. These are the ones that are particularly interesting for Fedora, the rest are in the 'Virtualization Tools' bugzilla product. == xen == https://bugzilla.redhat.com/499850 RFE: Implement the Xen PV-on-HVM drivers We want to re-gain support for Xen paravirt devices in HVM guests, but we're not quite clear yet that anyone is going to get to it any time soon. https://bugzilla.redhat.com/501720 upstart does not launch a login process on /dev/hvc0 in all cases Fedora isn't always setting up a tty for Xen PV guests any more. https://bugzilla.redhat.com/458385 Running gdb in F-9 x86_64 guest on RHEL 5.2 x86_64 host crashes guest Jeremy Fitzhardinge has reportedly fixed this upstream so we should apply those patches to F-11. https://bugzilla.redhat.com/499611 Hotplugging vcpus to an F-11 64-bit Xen domU doesn't work Justin Forbes has proposed a udev script to automatically online CPUs as they are added. = Resolved Bugs = == kvm == https://bugzilla.redhat.com/492838 kvm: PTHREAD_PRIO_INHERIT mutexes fail to unlock sometimes with 32 bit i686/PAE guest kernel, works on i686/non-PAE Avi heroically figured out this bug after much faffing about on everyone else's part. It turns out to need two separate fixes for the paravirt MMU. https://bugzilla.redhat.com/499307 BUG() in kvm_handle_fault_on_reboot() on amd64 host during RHEL5.3 guest install There are over a hundred of these logged to kerneloops.org. Turns out to be caused by the VirtualBox kernel module. WONTFIX. == qemu == https://bugzilla.redhat.com/498405 qemu disk image corruption with qcow2/virtio Avi looked into this and came up with a workaround patch. Much discussion ensued upstream with Avi, Kevin and Gleb as they grappled to understand the code and in the end Gleb came up with a simple fix. The fix was included in qemu-kvm-0.10.4 which is now available in F11 updates-stable. https://bugzilla.redhat.com/499666 Reboot fails when using qemu -kernel Glauber posted a patch to qem-devel for this and built the fix as an F-11 update. https://bugzilla.redhat.com/494075 openbios bug causes qemu-system-ppc "invalid/unsupported opcode" failure This seems to be due to a change in binutils in F11. Pavel Roskin fixed the problem in upstream openbios and a openbios-1.0-1.fc11 update has been pushed with the fix. We expect there are more issues to be resolved here. == libvirt == https://bugzilla.redhat.com/493692 Creating new VM; SELinux prevents opening iso image of install media libvirt wasn't correctly re-labelling shared or read-only images when starting a guest. Dan Berrange came up with a patch for this issue and built just in time for the test day. https://bugzilla.redhat.com/460649 libvirtd requires restart in order to detect new capabilities like KVM support Cole came up with a patch for this, posted upstream and built in F-11, also in advance of the test day. https://bugzilla.redhat.com/499791 virt-manager does not escape special characters in ISO file name libvirt gets XML attribute escaping wrong. DV has fixed upstream and that fix is available in libvirt-0.6.2-9.fc11. https://bugzilla.redhat.com/499584 info balloon is repeated in qemu log once per second Fixed in libvirt-0.6.2-10.fc11 by only logging monitor output to the debug logs, not the domain log file. https://bugzilla.redhat.com/501912 libvirt/qemu does not activate bridge if no IP address is assigned This little oversight was fixed upstream recently and the fix has been cherry-picked for F-11 in libvirt-0.6.2-11.fc11. https://bugzilla.redhat.com/499698 'virsh destroy' destroys multiple VMs Dan Berrange posted a fix for this to the bug report which is now upstream and in F-11 updates-testing. == virt-manager == https://bugzilla.redhat.com/491683 virt-manager no longer auto adjusts to guest screen size Dan Berrange tracked this down to a recent change which explictly sets the window size in virt-manager. The fix has been pushed to update-testing in virt-manager-0.7.0-5.fc11. https://bugzilla.redhat.com/499145 virt-manager appears to ignore arch selection Cole implemented this and and the patch has been include in the virt-manager-0.7.0-5.fc11 update. https://bugzilla.redhat.com/499589 virt-manager console widget doesn't know how to collect a 'username' for authentication with VNC Dan's patch to implement this is in virt-manager-0.7.0-5.fc11. https://bugzilla.redhat.com/495128 "New VM" dialog box misspells "operating" as "opertaing" Another minor victory in the War on Spelling Mistakes. Even the translations have been purged of this evil typo. https://bugzilla.redhat.com/499685 RFE - include virt type in virt-manager Guest->Details tab It's very hard for users to tell whether they're guest is actually using KVM. This new UI added by Cole for F-12 will make it easier. == libguestfs == https://bugzilla.redhat.com/501761 libguestfs requires qemu, not qemu-system-x86 or qemu-system-ppc Rich continues his crusade to over-inflate the dependencies of Fedora packages. == xen == https://bugzilla.redhat.com/499621 F-11 Xen 64-bit domU stack traces when unmounting a disk Justin backported the fix for this to the F-11 kernel. https://bugzilla.redhat.com/499592 F-11 Xen 64-bit domU cannot be started with > 2047MB of memory Chris Lalancette came up with a fix for this issue and Justin pushed it to F-11. Jeremy Fitzhardinge plans to push a slightly different patch upstream. == anaconda == https://bugzilla.redhat.com/496298 F11 Beta :: under KVM anaconda detect cdrom media because udev doesn't probe for filesystem type This blocker appears to have finally been stomped. https://bugzilla.redhat.com/499194 anaconda fails to install grub in KVM guest It seems anaconda was briefly broken wrt. installing grub in a KVM guest for a while because of /dev/ being unmounted. Fixed in later builds. = Ongoing Bugs = == qemu == https://bugzilla.redhat.com/496627 qemu-kvm es1370 sound card emulation segfault https://bugzilla.redhat.com/495964 qemu locks up at shutdown with sdl audio driver Tom London confirmed that the pulseaudio backend resolves this issue. However, qemu will not default to the pulseaudio backend even if it is enabled. This needs to be addressed upstream. https://bugzilla.redhat.com/477035 EFI BIOS support in qemu Peter Jones has been looking into this and keeping notes here: https://fedoraproject.org/wiki/User:Pjones/KvmEFI https://bugzilla.redhat.com/494541 [KVM] E1000 PXE boot fails with "No IP address" It looks like building with PXE_DHCP_STRICT helps at least the reporter, so an update with this enabled has been pushed to updates-testing. == libvirt == https://bugzilla.redhat.com/490191 virt-manager cannot open VM serial console because of /dev/pty permissions Dan Berrange comments that this can't be fixed until virt-manager uses qemu:///session by default. See also the VirtPrivileges F12 feature. == virt-manager == https://bugzilla.redhat.com/478418 virt-manager prevents key combinations like alt-f from being sent to the guest https://bugzilla.redhat.com/499362 virt-viewer prevents key combinations like alt-f from being sent to the guest Dan Berrange describes how virt-manager and virt-viewer needs to intercept, and block, various key combinations before they are processed by gtk+ so that they can be sent to the guest. He has fixed this for virt-viewer, but the update needs pushing.

a few comment about the current virt pacakges
by Farkas Levente 24 May '09

24 May '09

hi, yesterday i try to rebuild fedora packages for rhel/centos/epel-5 and i've got a few comments. i try to build these packages: bochs-bios-2.3.8-0.6.git36989b0d2.fc11.src.rpm etherboot-5.4.4-13.fc11.src.rpm gtk-vnc-0.3.8-8.fc11.src.rpm libvirt-0.6.3-10.fc11.src.rpm openbios-1.0-1.fc11.src.rpm python-virtinst-0.400.3-8.fc11.src.rpm qemu-0.10.4-5.fc11.src.rpm qemu-0.10.50-4.kvm86.fc12.src.rpm vgabios-0.6-0.6.c.fc12.src.rpm virt-manager-0.7.0-4.fc11.src.rpm virt-viewer-0.0.3-5.fc11.src.rpm - first of all i really don't like to trick used in bochs-bios and etherboot. these can be build on ix86 and has only noarch subpackages. why not just define as noarch for the main packages and and exclude/includearch only for ix86? it'd be cleaner and easier. i saw that you're waiting for a rpm bugfix, but currently (and probably later) it also won't compile on x86_64 in koji since it's exclude all ix86 packages! what's more it _is_ build on x86_64 just do not create any result binary rpm which more annoying! - on the other hand in this case bochs-bios subpackage called bochs-bios-data (since you can't call it bochs-bios cause of the above:-( and of course qemu-system-x86 wrongly requires bochs-bios in stead of bochs-bios-data. it's a bug! - bochs-bios install only /usr/share/bochs/BIOS-bochs-latest /usr/share/bochs/BIOS-bochs-legacy but qemu requires BIOS-bochs-kvm which not exist anywhere. a link should have to be create for any of the above file as BIOS-bochs-kvm either in bochs-bios or in qemu. anyway why bochs-bios pulled out of qemu when it's also in qemu? - libvirt BR qemu. why? which require all qemu package which require openbios-ppc, vgabios, bochs-bios-data, etherboot-*. so this is a dependency hell. imho it'd be useful to clean up! - openbios build only for the given arch, but qemu requires all qemu-system* so it can't be build eg on i386 for i386 since libvirt BR qemu! - in more package the in the subpackage "Group field must be present in package", so group name missing:-( and bacuse of this none of openbios, bochs-bios and etherboot can be build on epel:-( - this /etc/libvirt/qemu/networks/default.xml makes me crazy. since blow up my current guest's configs:-((( -- Levente "Si vis pacem para bellum!"

P2V and grub bootloader
by Dennis Jacobfeuerborn 24 May '09

24 May '09

Hi, I'm currently experimenting with converting a physical system to a virtual one. Using losetup, kpartx, etc. i was able to transfer the system to a volume group in an image file. My problem is that I don't know how to install grub on that image file. I can boot the VM with a rescue CD and then install it from there but I'd like to do this without having to boot the VM first. On the net I found some tutorials that mention mount-binding /dev to /new-root/dev, chrooting to /new-root and then doing a "grub-install /dev/sda" but wouldn't that overwrite the boot sector of my physical disk rather than the virtual one? I tried doing a "grub-install /dev/loop0" (with loop0 beeing the device node for the image file) but there I only get "/dev/loop0 does not have any corresponding BIOS drive". How can I install grub from outside the VM? Regards, Dennis

Best Way To Install Ubuntu 8.10 (AMD64) Guest?
by Robert L Cochran 24 May '09

24 May '09

Hi, I have a fully updated Fedora 11 with Virtualization. My laptop is a Dell Latitude E6400, 4 Gb of memory, Intel P9500 dual core processor with virtualization support. I want to install Ubuntu 8.10 Desktop (AMD64) as a guest in Fedora. What is the easiest way of installing it such that I have internet access, USB, and possibly RS-232 serial port access? Thanks!

ANNOUNCE: virt-inspector
by Richard W.M. Jones 19 May '09

19 May '09

Hi, I'm pleased to announce the first 'really working' version of virt-inspector. Source is in the libguestfs source repository: http://git.et.redhat.com/?p=libguestfs.git;a=summary Binaries are in Koji for Fedora 11 / Rawhide: http://koji.fedoraproject.org/koji/buildinfo?buildID=102697 (minimum version 1.0.27 required) This is a tool based around libguestfs which can inspect a virtual machine disk image and tell you some interesting things about what's inside it. Some of the things it can tell you: - What operating system(s) are installed, and what distros and versions. It currently covers RHEL releases, Fedora releases, Debian releases, and has limited support for Windows. - How disk partitions are expected to be mounted (eg. /dev/sda1 -> /boot) - What applications are installed. - What kernel(s) are installed. - What kernel modules are installed. It can produce output in plain text (as a report) or in XML (to feed into other programs). It uses libvirt (if available) to get details of inactive domains, or you can run it directly on disk images. Usage is simple: virt-inspector --xml domain > info.xml # xml report virt-inspector /path/to/disk.img | less # plain text report You can also use it as a wrapper for guestfish, so it mounts the guest disks in the correct places, eg: $ virt-inspector --fish /dev/Guests/CentOS5.img guestfish -a /dev/Guests/CentOS5.img -m /dev/VolGroup00/LogVol00:/ -m /dev/sda1:/boot $ eval `virt-inspector --fish /dev/Guests/CentOS5.img` Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems.

"does this guest need a Xen hypervisor?" - Generate a libvirt XML config file (partly overlaps the functionality of new 'virsh import|export*' functions: http://www.redhat.com/archives/libvir-list/2009-April/msg00401.html ) Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.

libguestfs broken dependencies on Fedora 10

Hello, during reading FWN I see, that not only I don't like broken dependencies in Fedora repositories. I have an suggestion, how to fix this and make it functional for Fedora 10. Richard, can you add qemu-0.10 (at least binary) into libguestfs package for Fedora 10? Please change you spec file, add qemu sources, compile qemu-kvm as alternate name, like qemu-kvm-libguestfs and configure your libguestfs to use this version of qemu/kvm. I don't use libguestfs rpm package yet, but using libguestfs from git repository with succes in similar way. I have only qemu-kvm copyed from rawhide as alternate name and compiled libguestfs as described above. Everything works fine. Installing qemu-0.10 from rawhide into my Fedora 10 resulted always with qcow2 image corruptios and this package does not worked for me. May be these problems are already fixed, but I still think, this is not a good idea. SAL

Hi Glauber, I've pushed qemu-0.10.4-4.fc11 to stable, since it's had some good testing: https://admin.fedoraproject.org/updates/F11/FEDORA-2009-5050 So, qemu-0.10.4-5.fc11 in testing just has the cpuid trimming backport now: https://admin.fedoraproject.org/updates/qemu-0.10.4-5.fc11 Also, now that I look more closely, Jan's cpuinfo in bug #499596 does actually contain nx. Maybe cpuid trimming won't help him after all?
