So that release took a bit longuer to stabilize, but as a result we hopefully have a good release :-) . It is tagged in git now, so the freeze is over, and the source tarball and F17 rpms are available at the usual place at : ftp://libvirt.org/libvirt/ Except for a few new API this release is more oriented toward incremental improvements and bug fixes, with also a large amount of documentation improvements and portability fixes: Features: - Introduce virDomainMigrate*CompressionCache APIs (Jiri Denemark) - Introduce virDomainGetJobStats API (Jiri Denemark) - Add basic support for VDI images (Martin Kletzander) - Introduce API virNodeDeviceLookupSCSIHostByWWN (Osier Yang) - Various locking improvements (Daniel P.

[libvirt] [PATCH 0/8] Web page updates/changes
by John Ferlan 04 Mar '13

04 Mar '13

I was [t]asked to make updates to the api webpage including an example of a code path from application into the driver. As I started on the task I found that the api webpage first needed a couple of updates just to fill in what seems to have been missing information. As I went through the various pages I realized that the 'better' location for the example code path seemed to be the internals page and thus I added it there. My simple example (hah!) was the virConnectOpen code path - I figured for a intro- duction to the internals web page - it'd be a good place to start. While I was doing this I used the hellolibvirt example a bit and based on information found on the 'api' page I added some more calls into the example to print network and disk information as well as more domain data. Finally while going through the pages I found a couple of places where drv pages weren't referenced although they were available, so I updated those (phyp and parallels). Hopefully I've figured things out correctly, but I'm sure if I have something a bit wrong someone will correct me. Making the figure was quite frustrating as xfig is a bit less forgiving than say office writer.

Then libvirt should also make sure that the XML we allow for non-egd virtio-rng is restricted to the two filenames that won't cause a qemu warning, or even modify the XML to not expose a filename in the first place. We haven't released libvirt 1.0.3 yet, so we still have a few hours in which such a change could be made before the XML becomes baked by a release. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH] qemu: fix wrong evaluation in qemuDomainSetMemoryParameters
by Satoru Moriya 04 Mar '13

04 Mar '13

19c6ad9a (qemu: Refactor qemuDomainSetMemoryParameters) introduced a new macro, VIR_GET_LIMIT_PARAMETER(PARAM, VALUE). But if statement in the macro is not correct and so set_XXXX flags are set to false in the wrong. As a result, libvirt ignores all memtune parameters. This patch fixes the conditional expression to work correctly.

[libvirt] [PATCH] util: use string libvirt to prefix error message instead of libvir
by Guannan Ren 04 Mar '13

BZ:https://bugzilla.redhat.com/show_bug.cgi?id=912021 Without error handler set, virDefaultErrorFunc will be called, the error message is prefixed with "libvir:". It become a little better by using prefix "libvirt:" when working with upper application.

[libvirt] libvirt does not logout of iscsi targets, causing system hang on shutdown
by Fritz Elfert 04 Mar '13

04 Mar '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys, There's a quite old bug entry here: https://bugzilla.redhat.com/show_bug.cgi?id=700010 I just stumbled over that very issue on F18. Doing a little bit debugging of the shutdown sequence, it turns out that - at least on my F18 installation - libvirtd is shutdown *after* iscsid, which makes it impossible for libvirt to perform the logout of the iscsi session properly. My local fix (diff) is attached. It simply adds another startup dependancy on iscsid.service which in turn delays iscsid shutdown until after libvirtd has stopped. Having that applied, the system shuts down properly again. I was asked to post that here for discussion... So please consider this trivial change for the next update.

[libvirt] libvirt-1.0.2 qith lxc and /proc/meminfo
by Thierry Parmentelat 04 Mar '13

04 Mar '13

Hello there I'm using libvirt-1.0.2 to spawn off linux containers We currently have 2 very similar setups that run on fedora 16 and f18 respectively And I'm seeing one weird difference concerning /proc/meminfo While everything is fine on the fedora16 world, on the fedora18 side here is what the container sees bash-4.2# ls /proc ls: cannot access /proc/meminfo: Permission denied 1 257 bus devices fb irq kpagecount mdstat net schedstat swaps tty 10 377 cgroups diskstats filesystems kallsyms kpageflags meminfo pagetypeinfo scsi sys uptime 15 522 cmdline dma fs kcore latency_stats misc partitions self sysrq-trigger version 16 542 consoles dri interrupts key-users loadavg modules pidsu slabinfo sysvipc vmallocinfo 18 acpi cpuinfo driver iomem keys locks mounts procprotect softirqs timer_list vmstat 19 buddyinfo crypto execdomains ioports kmsg lxcsu mtrr sched_debug stat timer_stats zoneinfo bash-4.2# ls -l /proc | grep meminfo ls: cannot access /proc/meminfo: Permission denied -????????? ? ? ? ? ? meminfo bash-4.2# cat /proc/meminfo cat: /proc/meminfo: Permission denied ===== we rebuild libvirt-1.0.2 more or less as is modulo a few features that are turned off, our specfile can be found here http://git.onelab.eu/?p=libvirt.git;a=blob;f=libvirt.spec the most obvious difference between both builds lies in using fuse: --- # fuse is used to provide virtualized /proc for LXC %if 0%{?fedora} >= 17 || 0%{?rhel} >= 7 %define with_fuse 0%{!?_without_fuse:1} %endif --- I was wondering what exactly should be the requirements on the root context for running this properly In particular the fuse rpm was not pulled as part of the libvirt dependencies, which might be an omission ? Can I expect my problem to go away if I make sure fuse gets installed ? Otherwise where should I try to look to solve this issue ? many thanks in advance -- Thierry
