Fedora 12 =========
Fedora 12 Beta slipped by a week, but was released on Oct 20:
https://fedoraproject.org/wiki/F12_Beta_Announcement
We're now in the final countdown to F12 GA. The first release candidate will be composed next week and, all going well, we should have a release on November 17.
Thankfully, the virt blocker list is now clear, but if you're looking to help with making Fedora 12 even better, there's no better place to start than the F12 target tracker bug:
https://bugzilla.redhat.com/showdependencytree.cgi?id=F12VirtTarget&hide...
There's over 100 bugs there that need your help!
Witty Tagline =============
Dan Berrange has done a great job of coming up with a "witty tagline" for each of the virtualization feature sets in previous Fedora releases:
https://fedoraproject.org/wiki/Virtualization/History
Fedora 11: The walled garden Fedora 10: Management at a distance Fedora 9: Farewell to old friends Fedora 8: Protection from the bad guys Fedora 7: The new kid on the block Fedora Core 6: Virtualization grows up Fedora Core 5: The future is now Fedora Core 4: Glimpse of the future
We need a tagline which describes our eclectic mix of features in Fedora 12. Any ideas?
Fedora Weekly News ==================
Dale Bewley has contributed another bunch of virtualization sections to Fedora Weekly News:
https://fedoraproject.org/wiki/FWN/Issue196#Virtualization https://fedoraproject.org/wiki/FWN/Issue197#Virtualization https://fedoraproject.org/wiki/FWN/Issue199#Virtualization
ABRT and qemu-kvm =================
It's quite common that we have to ask bug reports to collect a stack trace for a qemu-kvm segfault.
Is ABRT the future?
https://bugzilla.redhat.com/show_bug.cgi?id=528754#c1
Try this:
$> yum install --enablerepo=rawhide-debuginfo qemu-debuginfo $> yum install -y abrt abrt-cli abrt-addon-ccpp abrt-plugin-logger $> service abrtd restart
then when qemu-kvm crashes, you should be able to do e.g.:
$> abrt-cli --get-list $> echo n | abrt-cli --report $uuid > t.log
Anyone got ideas for a better way to use ABRT to catch virt related bugs? We could do with adding instructions to:
http://fedoraproject.org/wiki/How_to_debug_Virtualization_problems
Got Windows Guests? ===================
Rich Jones has added yet another weird and fantastical feature to libguestfs ... and he needs your help to check that it works:
http://www.redhat.com/archives/fedora-virt/2009-October/msg00128.html
If you have any Windows guests, then you can help Fedora to support Windows guests better by spending a few minutes testing the Windows Registry feature we just added to libguestfs 1.0.75.
Basically, the new virt-win-reg tool can be used to display entries from the registry in a Windows guest. How cool is that?

DOOM-O-METER: 198 bugs open four weeks ago, only 186 now!
Ongoing Bugs ============
== kernel ==
https://bugzilla.redhat.com/515741 2.6.30 kernel stopped supporting xattrs on hugetlbfs
John Cooper is working on getting a patch together for F-12.
https://bugzilla.redhat.com/524808 swiotlb should be enabled when VT-d setup fails
dwmw2 points out that if VT-d setup fails (because e.g. a bad BIOS is detected), then we should make sure that swiotlb is still enabled. Chris Wright has been working on the fix. All are agreed that this shouldn't be considered a release blocker.
https://bugzilla.redhat.com/530389 allow userspace to adjust kvmclock offset
Glauber has patches queued upstream to add new kvmclock ioctls and wants them backported to Fedora 12.
https://bugzilla.redhat.com/531270 TG3, kvm, ipv6 & tso data corruption bug
Rik van Riel discovered this TSO6 related issue with the tg3 driver which is causing traffic from his KVM guest to be corrupted.
https://bugzilla.redhat.com/528245 starting a KVM guest before wireless NIC is brought up results in "nf_conntrack: table full, dropping packet."
Paul Lambert reports that his machine locks up on boot if he sets his KVM guest to autostart. It looks like it may be related to the wireless connection not being available at that point, but we're still pretty far from narrowing the issue down.
== qemu ==
https://bugzilla.redhat.com/528754 qemu-kvm segfault caused by -soundhw es1370
Gene Czarcinski reported this qemu segfault and managed to obtain a stack trace for it.
https://bugzilla.redhat.com/528134 qemu should set O_CLOEXEC on all file descriptors
glibc is now forking a ptchown program under certain circumstances, and SELinux issues showed that we are leaking file descriptors into forked processes. Uli claims we should set O_CLOEXEC but Dan, Markus and Kevin disagree.
https://bugzilla.redhat.com/472236 KVM guests cannot boot PXE "local"
This bug was originally reported against Fedora 10, but apparently is still a problem in Fedora 12 with gPXE.
https://bugzilla.redhat.com/528764 qemu's SDL backend doesn't release the console framebuffer on exit
Matt Booth discovered this annoyance with qemu's SDL backend.
== libvirt ==
https://bugzilla.redhat.com/527736 libvirt can't create storage pool volumes on a FAT32 hard disk - 'cannot set file owner ... Operation not permitted'
Reported by Richard Hughes, looks like libvirt's fs storage backend just isn't handling this case correctly.
https://bugzilla.redhat.com/529363 virsh restore fails - failing to re-label the save file ?
sVirt related virsh restore failure.
== virtinst ==
https://bugzilla.redhat.com/528947 virtinst: Creating LVM volume on QEMU during VM creation fails
A virtinst traceback during cloning, fixed by Cole upstream but needing backporting.
== virt-manager ==
https://bugzilla.redhat.com/530210 virt-manager setfacl() fails on filesystems not mounted with the 'acl' option
Our solution for "qemu can't access my homedir" was to use setfacl to give it access. We're scuppered in the case where users have created the filesystem themselves without the 'acl' option listed in the defaults. We need a better error message for this case.
https://bugzilla.redhat.com/530948 virt-manager: switching VM to fullscreen pins the window to 1st virtual desktop
Stefan Assman is seeing very strange behaviour when trying to use virt-manager in fullscreen mode.
https://bugzilla.redhat.com/526952 virt-manager locks up frequently using remote connection
Problem reported by both Matt Booth and Chris Wright.
https://bugzilla.redhat.com/527714 Entering a non-numeric capacity creates a volume with 10000 MB
Another minor virt-manager quirk.
https://bugzilla.redhat.com/530448 RFE: virt-manager should provide a means to refresh storage pools
virsh has a 'refresh-pool' operation, but virt-manager doesn't expose it.
https://bugzilla.redhat.com/529956 16x16 icon in Virtual Machine Details window https://bugzilla.redhat.com/529954 virt-manager dialog buttons do not follow the HIG https://bugzilla.redhat.com/529955 virt-manager host details window does not honor button_have_icons setting https://bugzilla.redhat.com/529657 virt-manager accidentally showing tabs in VM details https://bugzilla.redhat.com/530096 virt-manager host details window does not need a menu
Another bunch of reports of virt-manager UI warts from Michael Monreal.
https://bugzilla.redhat.com/529217 virt-manager storage pool window appears behind dialog
This annoyance in Fedora 11 reported by James Laska is fixed upstream, but needs backporting.
https://bugzilla.redhat.com/530178 virt-manager right-click menu for connections should have a delete item
Yet another UI quirk, this time reported by Gianluca Cecchi.
https://bugzilla.redhat.com/529842 virt-manager: Storage browser should change window title when choosing ISO
"Choose Volume" was causing some confusion which could be avoided if it was changed to "Choose ISO".
== xen ==
https://bugzilla.redhat.com/523941 kernel 2.6.31-1[24].fc12 doesn't boot in xen PV guest on 64b host
Andrew Jones is busy debugging this and has successfully bisected the problem down to a specific upstream commit. Some debate in the bug as to whether we'd actually slip the release for it. In the end, it turned out to be fixed by 2.6.31.5 for unknown reasons.
https://bugzilla.redhat.com/531311 2.6.32 boot fails as Xen PV guest with stackprotector
Andrew also uncovered this issue with the Fedora 13 kernel.
https://bugzilla.redhat.com/526627 F11 Xen DomU unstable (2.6.30)
Reporters seeing consistent Fedora 11 Xen guest lockups, seemingly dependant on the clock source.
https://bugzilla.redhat.com/521800 kernel backtrace: possible recursive locking detected on Xen domU
A strange recursive locking warning under Xen which apparently doesn't make much sense.
Resolved Bugs =============
== misc ==
https://bugzilla.redhat.com/530015 Add libvirt to Virtualization group
Somehow when we split libvirt-client from libvirt, we failed to make sure that libvirt was still being pulled in by the Virtualization package group.
https://bugzilla.redhat.com/523914 Mouse does not move in PV Xen guest under RHEL-5.4
Wrangling of this complex blocker bug continued. Peter Hutterer (the evdev maintainer) came up with a way to allow evdev to be configured so it works like before. The fixes are now in rawhide.
== kernel ==
https://bugzilla.redhat.com/524229 Local migration of kvm guest fails in Fedora12 Alpha
Marcelo thought this was a pvmmu issue fixed in 2.6.31, but apparently not. After some more testing Marcelo now suspects it's a kvmclock related issue fixed by Glauber upstream. This is now fixed in rawhide.
https://bugzilla.redhat.com/526869 Add virtio_blk support cache flush (VIRTIO_BLK_F_FLUSH)
Justin has pulled this 2.6.32 patch into Fedora 12.
https://bugzilla.redhat.com/525890 Backport virtio patches for optimised virtio-net
We've decided to wait until 2.6.32 for these patches.
== qemu ==
https://bugzilla.redhat.com/531419 qemu issue with non-virtio NICs receiving heavy traffic volumes
Reported by Scott Tsai on the qemu-devel upstream list, patch was pulled into Fedora 12.
https://bugzilla.redhat.com/524734 KVM guest ext3 errors at shutdown when using virtio and a qcow2 backing file
Kevin debugged this, posted a patch upstream suitable for stable and we pulled it into F-12.
https://bugzilla.redhat.com/528901 qemu-kvm : msrs[] array in kvm_arch_save_regs() too small / may cause stack corruption
Ulrich Obergfell provided this excellent analysis of a savevm segfault in Fedora 11. Eduardo sent a fix upstream.
https://bugzilla.redhat.com/503156 qemu VNC :: xterm inside VM shows garbled text
The version of qemu in Fedora 11 appears to have a broken VNC CopyRect encoding implementation and this has been seriously annoying some users. In the absence of a confirmed fix, we've just disabled the encoding for now.
https://bugzilla.redhat.com/527653 /etc/init.d/ksm: line 69: [: -eq: unary operator expected
Minor bug with the ksm initscript now fixed in F-12.
https://bugzilla.redhat.com/527087 qemu-common postinstall scriptlet uses getent before it's installed
Bruce Jerrick points out this packaging error. Fixed in F-12 now.
https://bugzilla.redhat.com/526381 qcow2 performance bad under i/o load
CLOSED NOTABUG since these were compressed qcow2 images.
https://bugzilla.redhat.com/530059 VDE support in qemu?
CLOSED CANTFIX until someone packages VDE.
https://bugzilla.redhat.com/530136 guestfwd option doesn't allow supplementary chardev options like server,nowait
Rich Jones points out a problem with the -net user,guestfwd= option, but since libguestfs doesn't need it anymore and the new -chardev option upstream solves the problem, this is now marked CLOSED UPSTREAM.
https://bugzilla.redhat.com/528678 qemu-img does not correctly roundtrip data for VPC image format
This minor issue was caught by the libvirt-TCK test suite. Kevin reports that this is NOTABUG, but rather a limitation with the vpc file format.
https://bugzilla.redhat.com/526776 Add rtl8209 to gpxe-roms-qemu https://bugzilla.redhat.com/526781 Add rtl8209 to etherboot-zroms-kvm https://bugzilla.redhat.com/526243 Guest PXE booting doesn't work when using ne2k_pci NIC model https://bugzilla.redhat.com/526777 Guest PXE booting doesn't work when using ne2k_pci NIC model
Fixed this in F-11 and F-12.
== libvirt ==
https://bugzilla.redhat.com/523158 virsh restore causes libvirtd segfault virExec()
Dan Berrange identified the recent change that caused this regression. Fixed now in Fedora 12.
https://bugzilla.redhat.com/528162 Fix memory leak in libvirtd in F12
An upstream fix which needed backporting to F12.
https://bugzilla.redhat.com/526769 libvirt logrotate settings should roll over weekly instead of daily https://bugzilla.redhat.com/531030 log file sized increased by "compression"
Two requests to fix logrotate's handling of libvirt's qemu log files. Fixed for F-12.
https://bugzilla.redhat.com/517157 libvirt fails to start guest on NFS even when sebool virt_use_nfs is on
We never got around to backporting the fix for this to F-11 and other users had been reporting it. Now fixed in a F-11 update.
https://bugzilla.redhat.com/524732 org.libvirt.manage policy kit denial
This was due to there being no PolicyKit authentication agent running in the session.
== virt-manager ==
https://bugzilla.redhat.com/461962 virt-manager should support logical pool enumeration
Creating a lvm volume group using virt-manager is confusing, but Cole has fixed that upstream now.
https://bugzilla.redhat.com/440591 virt-manager: Add 'double click to connect' hint to connection row tooltip
Another UI annoyance fixed by Cole upstream.
https://bugzilla.redhat.com/526111 virt-manager add storage volume allows an empty name field https://bugzilla.redhat.com/526077 virt-manager toolbar buttons should have tooltips https://bugzilla.redhat.com/524083 virt-manager storage "Allocation" field can be set higher than "Max Capacity"
Fixed by virt-manager-0.8.0-7.fc12
== xen ==
https://bugzilla.redhat.com/521806 Unowned directory /usr/lib64/fs https://bugzilla.redhat.com/496135 missing dependency on PyXML
Justin Forbes fixed both of these F-12 xen packaging bugs.
https://bugzilla.redhat.com/531429 libvirt failed to disconnect and double free crashes on F12/rawhide with Xen
Pasi Karkkainen requested a couple of libvirt xen driver fixes from 0.7.2 be backported to Fedora 12.
