Dom0 kernels
by M A Young 28 Aug '09

28 Aug '09

I have built a new set of kernel packages based on fedora rawhide kernels and the xen/dom0/hackery branch of Jeremy's git repository ( http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=summary ). This batch (kernel-2.6.29-0.114.2.6.rc6.fc11) is available via the koji build system at http://koji.fedoraproject.org/koji/taskinfo?taskID=1149500 These are really for development and debugging purposes only, as I am still having problems getting them to boot, but others have reported more success at getting kernels based on this git repository working, so you might be lucky. Note to install these packages on Fedora 10 you will need to have rpm-4.6.0-1.fc10 installed (currently in updates-testing but it should be available in updates soon) because of the change to SHA-256 file digest hashing in recent Fedora 11 builds.

FESCo F-11 Virt features meeting
by Chris Lalancette 27 Feb '09

27 Feb '09

All, I attended the F-11 FESCo meeting on Friday (Feb 27). They talked about 4 Virt related features: sVirt - https://fedoraproject.org/wiki/Features/SVirt_Mandatory_Access_Control - Approved. They like the feature, but worried about getting the support into the Fedora package on time. They also asked about SELinux support with virt + LVM partitions, as well as sVirt support with LVM, but I didn't know. VirtVNCAuth - https://fedoraproject.org/wiki/Features/VirtVNCAuth - Approved. They said that the "how to test" section on the Feature page needs to be filled out better SharedNetworkInterface - https://fedoraproject.org/wiki/Features/Shared_Network_Interface - Deferred to F-12. Not enough of the bits are in place to make this feature "testable by users" by Tuesday. VirtImprovedConsole - https://fedoraproject.org/wiki/Features/VirtImprovedConsole - Approved. They want to see the release notes on the feature page filled in. -- Chris Lalancette

Fedora virt status

2009-03-03 Feature freeze (6 days) 2009-03-10 Beta Freeze (13 days) 2009-04-14 Final freeze (48 days) An early report this week because I'm about to disappear for three weeks. Just before the feature/beta freeze ... nice timing, I know! :-) F11 Features ============ Dale Bewley provides a timely reminder that all but one of the F11 virt features have not yet been approved by FESCo: http://www.redhat.com/archives/fedora-virt/2009-February/msg00088.html FWN === This weeks Fedora Weekly News is out with another great virtualization section: https://fedoraproject.org/wiki/FWN/Issue164#Virtualization Tablet Pointer ============== Dan Berrange did some experimentation with making Fedora be able to sanely handle a tablet pointer without extra configuration and filed these two bugs: https://bugzilla.redhat.com/487025 Add a HAL FDI file for the QEMU tablet device https://bugzilla.redhat.com/487028 Default to using the table in python-virtinst for F11 guests: The idea here is that if we use the tablet pointer with F11 guest by default it will fix the screwiness with mouse pointers in guests by using absolute pointer positioning rather than relative positioning. High Resolution in QEMU ======================= In order to use a higher resolution when running Fedora on qemu/kvm, we're planning on using the PCI subvendor ID to allow the Xorg cirrus driver to detect that it's a QEMU emulated card and use 1024x768. Dan Berrange filed two bugs to track this: https://bugzilla.redhat.com/487118 Need to add subsystem vendor ID for kvm/qemu cirrus card https://bugzilla.redhat.com/251264 xorg should use 1024x768 for kvm/qemu cirrus card Device Assignment ================= Several libvirt patch sets were posted to add device dettach, re-attach and reset support: http://www.redhat.com/archives/libvir-list/2009-February/msg00393.html http://www.redhat.com/archives/libvir-list/2009-February/msg00438.html http://www.redhat.com/archives/libvir-list/2009-February/msg00441.html Also, Chris Wright posted the patch for "remove_id" in sysfs: http://marc.info/?l=kvm&m=123545476703098 https://bugzilla.redhat.com/487103 QEMU ==== Rumour has it that there may be an upstream release Real Soon Now. The package reviews for the three new BIOS packages are still in progress: https://bugzilla.redhat.com/485417 https://bugzilla.redhat.com/485418 https://bugzilla.redhat.com/485420 Installer Debugging =================== A bug was filed about headless installs: https://bugzilla.redhat.com/487136 KVM Having problem In fedora 10 With no-gui This prompted a new tip to be added to: https://fedoraproject.org/wiki/Reporting_virtualization_bugs#virt-install In order to gain access to a serial console during the install, you can use -x "console=ttyS0". Using a serial console combined with a VNC install can be very useful for debugging e.g. <code>--nographics -x "console=ttyS0 vnc". Perhaps it might make sense for Fedora to use any available serial console if there is no graphics card? Probably not, though, since you have no idea whether anything is connected to the other end of the serial line - on a bare-metal headless server, such a policy would have us pointlessly driving unused serial lines. kvm-84 ====== The recently released kvm-84 has hit rawhide. Avi's release announcement is here: http://marc.info/?l=kvm&m=123465878918472 Tom London reports that qemu-kvm segaults for him when using the SDL graphics frontend. It appears the issue may be related to SDL's use of SSE/MMX instructions for bit blitting. https://bugzilla.redhat.com/487018 Segfault with kvm-84-1.fc11.x86_64.rpm (SDL related) libvirt-0.6.0 ============= libvirt-0.6.0-3.fc10 was pushed to f10-updates-testing this week. Another issue with libvirt-0.6.0 was reported: https://bugzilla.redhat.com/487013 virsh setvcpus hangs with libvirt-0.6.0 This turns out to be a recursive locking bug introduced by the major threading changes in the release. Busted Installs =============== Jeff Garzik reports that he sees x86_64 F10 installs hangs at "installing bootloader" under KVM: https://bugzilla.redhat.com/474116 This problem went away when he used 1Gb RAM instead of 512Mb. There is already another similar, but not identical bug, detailing an issue with x86_64 installs on 512Mb: https://bugzilla.redhat.com/480826 Fabian Deutsch also reports some F11 alpha installer issues under KVM. The first looks like a generic anaconda bug that also existed in F10: https://bugzilla.redhat.com/476433 The second seems to be an anaconda hang during a LiveCD install: https://bugzilla.redhat.com/484721 Neither of Fabian's issues look related to known pvmmu related crash in F11 alpha: https://bugzilla.redhat.com/480822 However, Mark Bidewell reported an issue with F11 Alpha installs to kvm@vger and this did turn out to likely be pvmmu related: http://marc.info/?l=kvm&m=123548745416389 Also, James Laska previously reported a kernel oops during install that may well be yet another pvmmu related issue: https://bugzilla.redhat.com/483648 Marcelo's pvmmu fix first made it in 2.6.26-rc5.git, so hopefully the world has been a better place since then. Rawhide Rebuild Failures ======================== Matt Domsch rebuilt all of rawhide in mock and found that etherboot, ruby-libvirt, gnome-applet-vm and xen failed to build: http://www.redhat.com/archives/fedora-virt/2009-February/msg00079.html http://www.redhat.com/archives/fedora-virt/2009-February/msg00080.html http://www.redhat.com/archives/fedora-virt/2009-February/msg00081.html http://www.redhat.com/archives/fedora-virt/2009-February/msg00082.html Xen dom0 ======== Michael Young completed the first dom0 build in Koji: http://www.redhat.com/archives/fedora-virt/2009-February/msg00085.html These are really for development and debugging purposes only, as I am still having problems getting them to boot, but others have reported more success at getting kernels based on this git repository working, so you might be lucky. Michael found an interesting issue where recently built F11 RPMs wouldn't install on F10 because F11 RPMs use SHA-256 checksums. F10 updates now contains a version of RPM which can handle these checksums. https://bugzilla.redhat.com/487140 Packages built with rpm-4.6.0-8.fc11 won't install on Fedora 10 x86_64 Xen DomU ======== Some discussion on fedora-kernel-list about the need to fix anaconda to install kernel-PAE on any machine which supports PAE: http://www.redhat.com/archives/fedora-kernel-list/2009-February/msg00079.ht… Michael Young also reported a lockdep warning during DomU boot which Jeremy has fixed in his Dom0 tree: https://bugzilla.redhat.com/487324 kernel/lockdep.c warning in xen guest boot dmesg Bugs ==== DOOM-O-METER: 188 open bugs last week, 192 this week. Baa! https://bugzilla.redhat.com/487190 virt-manager has hardcoded Requires: PolicyKit-gnome Does virt-manager really require PolicyKit-gnome? The KDE spin doesn't ship it. Looks like PolicyKit was fixed in 0.7 to allow us to only require PolicyKit itself. https://bugzilla.redhat.com/467687 Virtual network won't work until restart It appears that ip_forward was being set to zero because the NetworkManager and libvirtd services were incorrectly ordered. The "reporting virt bugs" wiki page has some details on how to diagnose the problem in future: https://fedoraproject.org/wiki/Reporting_virtualization_bugs#Networking

Accepted F11 Virt Features
by Dale Bewley 25 Feb '09

25 Feb '09

Howdy, I was touching up the virt release[1] notes a little bit. There are currently 5 virtualization related features[2] for F11: * KVM_PCI_Device_Assignment * KVM_and_QEMU_merge * Shared Network Interface * SVirt Mandatory Access Control * Virtualization VNC Authentication Only KVM PCI Device Assignment has been accepted[3] so far. The feature freeze is coming up in one week[4] (March 3rd). I assume if they are not listed as accepted at that time they shan't be included, barring fesco exception. Would the owners of the above features care to chime in about their (un)likelihood of inclusion in F11, or give em a little shove towards "acceptance"?

[Fwd: Fedora Test Day - CrashCatcher]
by Mark McLoughlin 25 Feb '09

25 Feb '09

Hey, Wondering if some folks fancy joining the test day tomorrow and e.g. making sure that CrashCatcher catches segfaults in qemu-kvm, libvirtd, virt-manager, virt-viewer etc .? Cheers, Mark.

F11 sensible mouse pointer movement
by Daniel P. Berrange 24 Feb '09

24 Feb '09

Just done some experimentation with USB tablet in Fedora 11 guests. It turns out we were just one tiny step away from it working correctly. Indeed, same applies for F10 and we didn't realize :-( In the guest, edit the HAL file /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi just adding <match key="input.product" contains="QEMU USB Tablet"> <merge key="input.x11_driver" type="string">evdev</merge> </match> Now shutdown the guest, and use virsh edit to add <input type='tablet' bus='usb'/> Now start the guest. The USB tablet will automatically configure and provide 1-for-1 mouse motion tracking with no pointer grab required Added 2 bugs to track this work so we get it done for F11 beta HAL https://bugzilla.redhat.com/show_bug.cgi?id=487025 virtinst https://bugzilla.redhat.com/show_bug.cgi?id=487028 You can try out the FDI change just fine on F10 if you're so inclined Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
