default tftp root dir in virt-manager or qemu?

by Gianluca Cecchi

Hello, I'm on a x86_64 F11 host. I created with success CentOS 5.3 and Windows 2003 vms from iso images. If i try to create a VM from virt-manager with pxe, I see from ps that there is the -boot n option, but there aren't any -tftp dir and/or -bootp file options.... Is there any default for qemu and/or virt-manager? If this helps, I'm trying to create a qemu/kvm virtual machine. ps output is: root 3577 1 99 14:52 ? 02:37:30 /usr/bin/qemu-kvm -S -M pc -m 768 -smp 1 -name slackware64 -uuid 4e3c9c56-695a-b5a5-ff87-ab0807b19d63 -monitor pty -pidfile /var/run/libvirt/qemu//slackware64.pid -no-reboot -boot n -drive file=/dev/vg_qemu01/slack64,if=ide,index=0 -net nic,macaddr=54:52:00:56:19:31,vlan=0 -net tap,fd=19,script=,vlan=0,ifname=vnet3 -serial pty -parallel none -usb -vnc 127.0.0.1:3 -soundhw es1370 The installation remains in attemp to get the tftp file without success (it give "no filename") It seems that the guest gets one of the available ip provided by dhcpd, also it founds dhcpd and tftp server: both are set to 192.168.122.1 (the server itself with its virbro default interface). No configuration done by me. I see /etc/libvirt/qemu/networks/default.xml with some parameters but I don't know if and how I can put here also tftp settings.... Thanks for any pointer. Bye, Gianluca

[RFC/PATCH] libguestfs: build Debian based appliance

by Guido Günther

Hi Rich, attached patches allows to build the appliance based on Debian (or any Debian based distribution supported by debirf) by using e.g.: ./configure --with-repo=squeeze --with-mirror=http://apt:9999/debian Please note that the third patch isn't to be applied yet, it simply overwrites the contents of make/update.sh.in with the stuff we need for Debian. Also when building a fixed (#509381) debirf is needed which has just been uploded to unstable. Cheers, -- Guido

USB passthrough

by Mark McLoughlin

Hey, At FUDCon yesterday, Paul asked me about how to get KVM USB device passthrough working and I had to admit I'd never tried it. So, after some poking with F-11, here's what I found: 1) You need selinux-policy-targeted-3.6.12-55.fc11 or later 2) Make sure the virt_use_usb SELinux boolean is enabled, which it should be by default: $> getsebool virt_use_usb virt_use_usb --> on $> setsebool -P virt_use_usb on 3) Plug your device in, and if it's a USB mass storage device, make sure it's not mounted in the host 4) In virt-manager, open the VM window, go to the details tap, clock 'Add hardware', select 'Phyiscal host device', choose 'USB device', then the device you wish to passthrough 5) Take a peek at the device in the guest XML config $> virsh dumpxml xp ... <devices> ... <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x0dda'/> <product id='0x0001'/> </source> </hostdev> </devices> 6) Start the guest and check whether the guest can see it. If not, check /var/log/libvirt/qemu/$guest.log because qemu will happily start up even if the device cannot be assigned. 7) It sucks that the device has to be plugged in before you start the guest; qemu now has a "autoconnect" mode which probably makes sense for libvirt to use by default, see bug #508645 Cheers, Mark.

[PATCH] Add pipe support to guestfish

by Richard W.M. Jones

This patch adds support for pipes to guestfish, so you can pipe output from a guestfish command through a command on the host. The canonical example is: ><fs> hexdump /bin/ls | less Another example, looking for root backdoors in the password file: ><fs> cat /etc/passwd | awk -F: '$3 == 0 { print }' | grep -v ^root: Anything right of the first pipe symbol gets passed to the local shell, thus expansion, redirection and so on work on that.

[PATCH] Cleanup XML output of virt-inspector

by Matthew Booth

The attached patch makes some changes to the XML output of virt-inspector. Firstly, it changes the output code to use XML:Writer. This changes: * Single quotes for attributes become double quotes * All data is properly escaped * Indentation In practise, these should be invisible. It also changes the output semantically in 2 ways: * /operatingsystems/operatingsystem/os is renamed to /operatingsystems/operatingsystem/name * /operatingsystems/kernels/version becomes an attribute of /operatingsystems/kernel for consistency with initrds Are these changes likely to cause problems?

20% cpu usage spikes with idle centos 5.3 guest on F11

by Dennis Jacobfeuerborn

Hi, When I run a centos 5.3 x86_64 guest on my F11 x86_64 system with kvm I see the qemu-kvm process cpu usage jump to ~20% every few seconds even though the guest is completely idle (I even disabled the HAL polling for /dev/hdc). Does anyone have an idea what could be the cause of this or how find the reason for this behavior? Regards, Dennis

libvirt and iptables rules added

by philippe.marcovici＠free.fr

Hi, My iptables rules are not permissives. For exemple, my default iptables's rules are DROP. libvirt inserts some iptables's rules. But, because my rules are not permissives, some DROP are generated. I fix it with a script, but i am looking for an automatization. I saw an directory named iptables with sub-directories named nat and filter in /var/lib/libvirt (all empty) : # ls -r /var/lib/libvirt/iptables nat filter My questions, in this context, are : - Can i use this directories to put some iptables rules who will be loaded and unloaded with libvirtd ? - If yes, how i must set them ? - If no, any others solutions ? Thanks.

Fedora virt status

by Mark McLoughlin

F-12 Schedule ============= Phew, Fedora 11 has just been released and Fedora 12 is already coming at us hard: http://fedoraproject.org/wiki/Releases/12/Schedule 2009-07-28 Feature Freeze (36 days) 2009-09-22 Beta (Final Development) Free (92 days) 2009-10-20 Final Release Compose (120 days) F-12 Features ============= We've prepared a good bunch of feature pages so far for F-12: http://fedoraproject.org/wiki/Category:F12_Virt_Features In the kernel related space we have: - SR-IOV - KSM - Huge pages For QEMU, we have: - Stable PCI Addresses - Stable Guest ABI - KVM NIC hotplug - VNC resource tunnel In the libvirt space we have: - VirtPrivileges - VirtAuthorization - Host network interface APIs - Storage management APIs - TCK General virt tools related features include: - Hostinfo - VirtAppliances Also, of note is the feature describing NetworkManager's forthcoming support for bridged networking: http://fedoraproject.org/wiki/Features/NetworkManagerBridging Please do jump in and give help or feedback where you can! F-12 Release Engineering ======================== Some of the Fedora release engineering folks held a Fedora Activity Day (FAD) at Red Hat's offices in Raleigh recently: http://fedoraproject.org/wiki/Fedora_Activity_Day_Fedora_Development_Cycl... They came away from the meeting with a bunch of proposals intended to improve the Fedora development process: http://fedoraproject.org/wiki/Milestone_Adjustment_Proposal What was called the Preview release is now called Beta, what was Beta is now called Alpha and what was called Alpha is no more. http://fedoraproject.org/wiki/Israwhidebroken.com_Proposal The goal is to have a place where people can go to find the "last known good" rawhide tree. http://fedoraproject.org/wiki/Koji_Build_Autosign_Proposal All packages coming from Koji will be signed - i.e. rawhide packages will be signed. http://fedoraproject.org/wiki/Critical_Path_Packages_Proposal A core set of packages will receive special attention when they are being updated to try and reduce the chance of major regressions. http://fedoraproject.org/wiki/No_Frozen_Rawhide_Proposal Rawhide will no longer freeze when we hit the Beta Freeze, instead rawhide will continue to be published from the devel/ CVS branch and there will be new install trees immediately available for the new CVS branch (e.g. the F-12/ branch). Fedora Community Portal ======================= A new web interface for Fedora community members is no available: https://admin.fedoraproject.org/community/ Fedora Community provides a window into the Fedora distribution, leveraging the power of Fedora's Account System, Bodhi, Bugzilla, Koji, and PackageDB into a single user-friendly website. ... Fedora Community is designed to simplify Fedora workflows and bring transparency to Fedora processes. qemu-0.11 ========= Anthony Liguori posted his plans for QEMU's 0.11 release: http://lists.gnu.org/archive/html/qemu-devel/2009-06/msg01575.html 0.10.0 was released on March 2nd so following with the 6 month release cycle, that would put 0.11.0 at September 2nd. Based on the experiences with the stable releases, here's what I'd recommend: o On July 15th, fork master -> stable-0.11 o Change version to 0.10.90 o Release qemu-0.11.0-rc1 o Release additional -rcN releases every 1-2 weeks o Introduce a new maintainer for stable-0.10 (via git pulls) o At least 1 week before release, hopefully we'll have the final -rcN that we can then declare 0.11.0. Avi confirmed that he plans to mirror these releases with matching qemu-kvm releases. For Fedora 12, we already have a 0.11 snapshot (0.10.50-6.kvm86.fc12) and as new snapshots become available we will pull them in. This means we should have a feature frozen qemu in time for the F-12 feature freeze and a final 0.11 release in time for the final F-12 freeze. libguestfs ========== Rich Jones continues rocking with his libguestfs working, with a whole load of interesting stuff on the fedora-virt list and his blog. Rich always does his best to assure us that he really is crazy, but his libguestfs "supermin appliance" work takes the biscuit: http://www.redhat.com/archives/fedora-virt/2009-June/msg00118.html The supermin appliance removes the kernel and all the executable libraries and programs from the appliance. That just leaves a skeleton of config files and some data files, which is obviously massively smaller than the normal appliance. At runtime we rebuild the appliance on-the-fly from the libraries and programs on the host (eg. pulling in the real /lib/libc.so, the real /bin/bash etc.) The new appliance is a mere 500K, so libguestfs RPMs will be a lot smaller. libosinfo ========= Cole Robinson posted an RFC detailing his plans to create a libosinfo library replacing python-virtinst's OS_TYPES dictionary which contains valuable information on the preferred configuration for different guest OSes: http://www.redhat.com/archives/fedora-virt/2009-June/msg00100.html I've done the initial work for a new library, libosinfo (better name recommendations appreciated). This library will provide OS meta data for use in virt applications, replacing the dictionary we currently keep in virtinst. FWN === Another couple of Fedora Weekly News virt roundups from Dale Bewley: http://fedoraproject.org/wiki/FWN/Issue179#Virtualization http://fedoraproject.org/wiki/FWN/Issue180#Virtualization Xen === Gerd is planning on pushing a xen-3.4.0 update to F-11: http://www.redhat.com/archives/fedora-virt/2009-June/msg00032.html Not yet. I wanna give it a bit more testing in rawhide. Also it looks like xensource wants to release 3.4.1 quickly to fix a bunch of important bugs. I think it is a good idea to wait until that one is out, then update F11 straight to xen-3.4.1. Also xen 3.4 bumps the shared library major for some libraries from 3.2 to 3.4, so I'll have to figure what breaks due to that and coordinate the update. I know xenner is affected. Libvirts seems to do fine as it needs libxenstore only which is still at 3.0. Didn't investigate yet what else might need a rebuild. Also, Michael Young continues to push new Dom0 kernel builds: http://www.redhat.com/archives/fedora-virt/2009-June/msg00097.html Unfortunately, Dom0 seems to have missed the 2.6.31 boat, so Dom0 support in Fedora 12 looks highly unlikely. Bugs ==== = New Bugs = == kvm == https://bugzilla.redhat.com/504376 F-11 guest takes 45 minutes in mke2fs for 8gb fs on virtio disk with a sparse backing file A report of mke2fs taking forever during an anaconda install of an F-11 guest when using a virtio disk with a sparse backed file. Apparently, SLES-11 doesn't appear to suffer from the problem. https://bugzilla.redhat.com/505695 Poor KVM guest performance doing kernel builds (100+% overhead, w/ 8vcpu and virtio) Another report from Erik highlighting performance problems with KVM and disk I/O. https://bugzilla.redhat.com/507500 "MAX_LOCK_DEPTH too low!" warning during kvm guest startup https://bugzilla.redhat.com/507535 GPF in nf_conntrack_alloc() with KVM guests (2.6.31) An oops in core networking code as a result of routing packets back and forth between two guests. == qemu == https://bugzilla.redhat.com/506170 removing virtualization packages leaves qemu-system-x86 'yum groupinstall Virtualization' installs qemu-system-x86 via the qemu-kvm meta-package, but 'yum groupremove Virtualization' only removes qemu-kvm. Looks like expected behaviour for yum. https://bugzilla.redhat.com/507626 qemu-kvm VNC :: major display tearing garbage with windows guest and scrolling windows This looks like a similar issue to xterm getting garbled in a Fedora guest (bug #503156) https://bugzilla.redhat.com/506585 qemu-nbd dies with 'nbd.c:nbd_receive_request():L465: read failed' Looks like qemu-nbd dies when a client closes its end. https://bugzilla.redhat.com/505109 qemu ppc/ppc64 boot says "Boot failure! No secondary bootloader specified" Yet another bug with the ppc target. This time only in rawhide. == libvirt == https://bugzilla.redhat.com/507271 libvirt always places IDE disks before virtio/scsi disks If you attach an IDE disk to a guest booting from a virtio disk, libvirt ends up sorting the disks such that the guest will try and boot from the IDE disk. https://bugzilla.redhat.com/468384 RFE: use virt-manager to create network bridges A bugzilla basically requesting the 'Shared Network Interface' F-12 feature. https://bugzilla.redhat.com/505625 libvirtd segfault during virsh dominfo on security model 'virsh dominfo' was causing libvirtd to segfault because the selinux was blown away by virGetCapabilities(). Fixed upstream, needs to be pulled into F-11. https://bugzilla.redhat.com/506590 libvirt should ignore NUMA cells with missing topology It turns out some NUMA cells can be missing topology information, and libvirt should ignore these. Dan has come up with a patch which works well for the reporter. https://bugzilla.redhat.com/507405 virsh: renaming of guests creates a copy https://bugzilla.redhat.com/507555 libvirt starting a guest with ISO on NFS mount fails when unnecessarily setting SELinux file context Tim Waugh supplied a patch for this one. == svirt == https://bugzilla.redhat.com/506250 svirt prevents symlinks to be used in disk image paths If any part of a disk image path is a symlink, svirt denies qemu access to it. This will be fixed in a selinux-policy update soon. == virtinst == https://bugzilla.redhat.com/504604 virtinst ignores VirtualDisk(sparse = False) and doesn't pre-allocate the disk image Pre-allocation of disk images was disabled until it could be done without blocking libvirtd. This was fixed in libvirt-0.6.3, so to enable nonsparse disks in F-11 we would need to first backport the change from 0.6.3. https://bugzilla.redhat.com/505317 virtinst: make SLES11 guests use virtio by default Looks like SLES11 guests work well with virtio, should make virtinst enable it by default. == virt-manager == https://bugzilla.redhat.com/504605 virt-manager gets sparse/nosparse mixed up in New VM dialog virt-manager currently gets confused between sparse/nonsparse. Not that it matters since virtinst currently ignores it. https://bugzilla.redhat.com/504326 virt-manager's new VM dialog does not use storage pool interface https://bugzilla.redhat.com/502204 virt-manager's dialog to connect an existing CD-ROM to an ISO does not use storage pool interface A couple of places where we should be using the storage poll interface in virt-manager. Cole has now fixed these upstream. == virt-mem == https://bugzilla.redhat.com/505072 virt-mem "invalid argument in virDomainLookupByUUIDString" error A known error with the virt-mem tools on F-11, Rich has a patch somewhere. = Resolved Bugs = == qemu == https://bugzilla.redhat.com/506435 kvm: -kernel option seems broken Re-basing our qemu-roms-more-room.patch onto 0.10.5 introduced this regression. Fixed in qemu-0.10.5-3.fc11 https://bugzilla.redhat.com/499060 vgabios regression - 1440x900 resolution no longer available Glauber has cherry-picked the code to fix this from 0.6c and pushed a vgabios-0.6b-2.fc11 update to F-11. https://bugzilla.redhat.com/501545 "qemu-kvm -vga std" broken with vgabios 0.6c Tom London bisected the problem down to a specific upstream commit. It turns out the qemu is missing some code (which is in latest boch, but not qemu) in order for 0.6c to work. We've reverted to 0.6b (with some changes cherry-picked from 0.6c) in F-12 for now. == kvm == https://bugzilla.redhat.com/504374 kvm: hw DR_* watchpoint registers are ignored KVM in 2.6.29 does not virtualization the x86 debug registers so GDB watchpoints do not work. However, this is implemented in 2.6.30. == etherboot == https://bugzilla.redhat.com/506616 [qemu netboot] Eliminate 3 second delay on PXE boot Request to simply rebuild etherboot with ASK_BOOT=-1 in order to eliminate a pointless 3 second delay that most people don't ever see. https://bugzilla.redhat.com/507391 qemu-kvm PXE boot with e1000 results in bogus packets Several people have reported PXE using a virtio NIC doesn't work in F-11. It turned out to be an issue with gcc re-ordering writes and was fixed simply by appropriately using the 'volatile' keyword for the packet header. Fix available in etherboot-5.4.4-16.fc11 == svirt == https://bugzilla.redhat.com/499259 svirt denials breaks KVM PCI device assignment The virt_manage_sysfs SELinux boolean was added quite some time ago which is enough to use PCI device assignment with SELinux in enforcing mode. https://bugzilla.redhat.com/504444 svirt denials break USB device passthrough Similar to bug #499259 where svirt breaks PCI passthrough, svirt is denying qemu access to /proc, breaking USB passthrough. Dan Walsh has added a virt_use_usb boolean to selinux-policy which, if enabled, fixes the problem. == libvirt == https://bugzilla.redhat.com/506737 virt-manager should allow VM names with spaces in them Apparently this is a 'feature', so WONTFIX. == virtinst == https://bugzilla.redhat.com/484099 virt-install SASL authentication support virt-install doesn't currently have support for authenticating using SASL. Cole has fixed this upstream now. https://bugzilla.redhat.com/506319 virtinst errors finding default bridge: upsets virt-manager Cole fixed this upstream. = Ongoing Bugs = == qemu == https://bugzilla.redhat.com/473154 Virtual machine fails to start without cdom - qemu: could not open disk image /dev/sr0 Eduardo has posted a variant of Cole's patch upstream; Anthony has requested further changes. https://bugzilla.redhat.com/501131 qemu segfault when VNC client disconnects Gerd has fixed this upstream, just need to back-port the patch to F-11 now. https://bugzilla.redhat.com/504273 qemu-system-ppc on ppc host fails with "no opcode defined" It looks like this bug should be fixed by a change upstream to disable gcc optimizations for translate.c. Pavel still sees "invalid opcode" errors, though. A qemu-0.10.5-3.fc11 update has been pushed which might help. == virt-manager == https://bugzilla.redhat.com/503784 memory/vcpus changes in virt-manager do not persist across libvirtd restart Erik Jacobson points out that this issue affects CPU changes as well as memory. virt-manager needs to explicitly make these config changes persistent. https://bugzilla.redhat.com/503786 virt-manager refuses to increase guest memory until max memory change is first applied Cole has fixed this upstream. == koan == https://bugzilla.redhat.com/493414 Windows installs require manual reboot in the middle koan needs to acquire the ability to re-start a guest once the first stage of the install has completed.
