Hi, attached patch makes the example work again with recent pygobject-3.0 which doesn't allow to "import gtk" anymore.

[libvirt] [PATCH v5] Add support for systemd init service
by Daniel P. Berrange 18 Nov '11

18 Nov '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> This patch adds support for a systemd init service for libvirtd and libvirt-guests. The libvirtd.service is *not* written to use socket activation, since we want libvirtd to start on boot so it can do guest auto-start. The libvirt-guests.service is pretty lame, just exec'ing the original init script for now. Ideally we would factor out the functionality, into some shared tool. Instead of ./configure --with-init-script=redhat You can now do ./configure --with-init-script=systemd Or better still: ./configure --with-init-script=systemd+redhat We can also now support install of the upstart init script In v5: - Actually include the changes to configure.ac I mentioned in v4. * configure.ac: Add systemd, and systemd+redhat options to --with-init-script option * daemon/Makefile.am: Install systemd services * daemon/libvirtd.sysconf: Add note about unused env variable with systemd * daemon/libvirtd.service.in: libvirtd systemd service unit * libvirt.spec.in: Add scripts to installing systemd services and migrating from legacy init scripts * tools/Makefile.am: Install systemd services * tools/libvirt-guests.init.sh: Rename to tools/libvirt-guests.init.in * tools/libvirt-guests.service.in: systemd service unit --- configure.ac | 46 ++++++++++++++---- daemon/.gitignore | 1 + daemon/Makefile.am | 98 +++++++++++++++++++++++++++++--------- daemon/libvirtd.service.in | 20 ++++++++ daemon/libvirtd.sysconf | 3 + libvirt.spec.in | 93 +++++++++++++++++++++++++++++++++++- po/POTFILES.in | 2 +- tools/Makefile.am | 61 +++++++++++++++++++----- tools/libvirt-guests.service.in | 13 +++++ 9 files changed, 288 insertions(+), 49 deletions(-) create mode 100644 daemon/libvirtd.service.in create mode 100644 tools/libvirt-guests.service.in diff --git a/configure.ac b/configure.ac index 3b7535e..58c2740 100644 --- a/configure.ac +++ b/configure.ac @@ -329,16 +329,41 @@ dnl init script flavor dnl AC_MSG_CHECKING([for init script flavor]) AC_ARG_WITH([init-script], -

[libvirt] [ANNOUNCE] libguestfs webinar TOMORROW (Friday)
by Richard W.M. Jones 18 Nov '11

18 Nov '11

I'll be holding a libguestfs live “webinar” tomorrow, Friday, 18th November 2011 at 16:00 UTC. To convert the date and time to your timezone, do: date -d '2011-11-17 16:00Z' The programme will include: - An introduction to libguestfs features. - Live demonstrations of guestfish, a Python program, inspection, and image resizing. - An overview of major new features in RHEL 6.3. - The opportunity to ask questions on any technical topic related to libguestfs. This is going to be a Webex conference. It's possible, albeit difficult, to get Webex working on Linux. You will need the Java plugin for your browser, and there are some other tips on my blog: https://rwmj.wordpress.com/2011/11/17/libguestfs-web-seminar-this-friday/ The Webex conference link, an accompanying handout, and other details will be posted to the above URL ^^ shortly before the session starts. Don't worry if you can't make it or can't get Webex to work, as it will all be recorded and placed online in an open format as soon as we can afterwards. This seminar is sponsored by Red Hat. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine. Supports Linux and Windows. http://et.redhat.com/~rjones/virt-df/

[libvirt] [PATCH V4 00/10] Make inner workings of nwfilters more flexible + extensions
by Stefan Berger 17 Nov '11

17 Nov '11

The following series of patches re-does some of the inner workings of nwfilters with the goal to enable users to write filters that have other than the system-known chains supported right now ('root','arp','rarp','ipv4' and 'ipv6'). Ideally users should be able to provide a chain name in the chains XML attribute and either be able to jump to it as an 'action' or have the chain created automatically as it is the case right now for those chains enumerated before. The latter is now added in this patch series as well. I am first introducing internal priorities for the chains mentioned above so that their creation can be made more flexible -- currently their creation and the order in which they are accessed is hardcoded. This largely does away with the hardcoded stuff. All assigned priorities have negative values. Later on the priorities for the chains are made accessible via an XML attribute. Further, filters will be automatically accessed from the (ebtables) interface 'root' chain using the prefix of the name of the chain. As an example, the following filter will be accessed from the root chain for 'arp' packets since its name 'arp-xyz' has the prefix 'arp'. <filter name='test-arp-xyz' chain='arp-xyz' priority='-650'> <uuid>94abeecc-c956-0ac8-1f49-a06ee8995688</uuid> <rule action='accept' direction='out' priority='100'> <arp opcode='Request_Reverse' arpsrcmacaddr='$MAC' arpdstmacaddr='$MAC' arpsrcipaddr='0.0.0.0' arpdstipaddr='0.0.0.0'/> </rule> <rule action='accept' direction='inout' priority='500'/> </filter> In another step the priorities of rules is extended to also allow negativ values. This then allows the creation of rules and chains in the interface 'root' chain to be mixed so that the following layout becomes possible: Bridge chain: libvirt-I-vnet0, entries: 6, policy: ACCEPT -p IPv4 -j I-vnet0-ipv4 -p ARP -j I-vnet0-arp -p ARP -j ACCEPT -p 0x8035 -j I-vnet0-rarp -p 0x835 -j ACCEPT -j DROP In the above list of rules the '-p ARP -j ACCEPT' can now be found in between the 'jumps' to protocol-specific chains, which allows for more efficient rule evaluation. I did testing with the test cases in libvirt-tck as well as those in the tests/ directory and did not see any regressions. v4: - assign priority to chain according to name prefix - change default (internal) priorities of chains (by +200) - fix memory leak Regards, Stefan

[libvirt] New feature for libvirt
by Amit Tewari 17 Nov '11

17 Nov '11

Hi, I wanted to suggest a new feature development in libvirt network filter. Currently in libvirt network filter there is no support for ip aliasing, but we want to add this feature so that libvirt learns multiple ip address for a virtual machine. With this feature we will be able to get no-ip-spoofing filter works on machine with ip aliasing. Currently if we apply no-ip-spoofing filter on a virtual machine with ip aliasing then only one ip address is earned by libvirt ,due to this other aliased ip address packets are not allowed to route out of the machine. With this new feature libvirt network filter will work on machine with multiple ip addresses on a interface(ip aliasing) Regards Amit Tewari DISCLAIMER: ----------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.

[libvirt] Upgrade-problems from qemu-0.14.1 + libvirt-0.8.4 to qemu-0.15.1 + libvirt-0.9.6: Why I think multifunction=on is a bad idea...
by Philipp Hahn 17 Nov '11

17 Nov '11

Hello, this mail is something between a bug report and a warning to other users of libvirt, before they also experience the problem I encountered today: I just hat the painful experience of trying to install some newer versions of qemu(-kvm) and libvirt on a system with many managedsave-states and many snapshots. They are now all broken because 1. Newer qemu(-kvm) uses iPXE instead of etherboot, which have different ROM file sizes, which aborts loading the old VM state. So be careful to not delete your old PXE-ROM images. 2. libvirt defaults to add ',multifuntion=on' to the (in my case) rtl8139 network card and balloon-driver, which produces the "really helpful" message of qemu: warning: error while loading state for instance 0x0 of device '0000:00:03.0/rtl8139' or qemu: warning: error while loading state for instance 0x0 of device 'ram' Nothing you can't fix with installing the old etherboot-qemu package and some dirty "dd"-hackery on your saved files and snapshot xml files to add an explicit 'multifunction=off', but hard to diagnose and annoying enough. So even if the qemu people try to be backward compatible with their VMState format, libvirt doesn't seem to handle backward compatibility taht good at the moment. Perhaps it would help to not (only) store the XML domain configuration for snapshots and managedsave-files, but the exact qemu-argv string to at least get libvirt out of any backward incompatible changes when re-constructing the qemu command line from the XML data. Sincerely Philipp PS: I hope that info helps other people when getting those messages. -- Philipp Hahn Open Source Software Engineer hahn(a)univention.de Univention GmbH Linux for Your Business fon: +49 421 22 232- 0 Mary-Somerville-Str.1 D-28359 Bremen fax: +49 421 22 232-99 http://www.univention.de/

[libvirt] Libvirt block live migration with OpenStack Diablo
by Doude 17 Nov '11

17 Nov '11

Hi all, I use OpenStack Diablo release 2011.3-0ubuntu6.2 on ubuntu 11.10 with libvirt 0.9.2-4ubuntu15.1 I try to block migrate a VM from one host to another one. OpenStack uses the 'migrateToURI' method from libvirt python library. But this call fails. Libvirt log : - Source host: 18:27:30.475: 24622: error : remoteIO:5985 : unable to set user and group to '107:118' on '/var/lib/nova/instances/instance-000000b7/console.fifo.in': No such file or directory - Target host: 27:29.737: 27244: error : virSecurityDACSetOwnership:125 : unable to set user and group to '107:118' on '/var/lib/nova/instances/instance-000000b7/console.fifo.in': No such file or directory 18:27:29.917: 27244: error : virSecurityDACRestoreSecurityFileLabel:143 : cannot resolve symlink /var/lib/nova/instances/instance-000000b7/console.fifo.out: No such file or directory So the migration fails.
