[libvirt] [PATCH] cgroup: Don't fail to start a VM when DBus isn't compiled in or running
by Peter Krempa 31 Aug '13

31 Aug '13

The systemd code to create cgroups has fallback means built in, but fails to engage them if a host isn't running DBus or libvirtd is compiled without DBus (yes, you still don't need to run DBus). This patch changes the return value in case DBus isn't available to so that the fallback code can be activated and cgroups are created manually. --- src/util/virsystemd.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/util/virsystemd.c b/src/util/virsystemd.c index 251b846..25fcf96 100644 --- a/src/util/virsystemd.c +++ b/src/util/virsystemd.c @@ -145,8 +145,10 @@ int virSystemdCreateMachine(const char *name, char *username = NULL; char *slicename = NULL; - if (!(conn = virDBusGetSystemBus())) - return -1; + if (!(conn = virDBusGetSystemBus())) { + virResetLastError(); + return -2; + } if (privileged) { if (virAsprintf(&machinename, "%s-%s", drivername, name) < 0) -- 1.8.3.2

[libvirt] [PATCH] Add documentation for access control system
by Daniel P. Berrange 31 Aug '13

31 Aug '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> This adds two new pages to the website, acl.html describing the general access control framework and permissions models, and aclpolkit.html describing the use of polkit as an access control driver. page.xsl is modified to support a new syntax <div id="include" filename="somefile.htmlinc"/> which will cause the XSL transform to replace that <div> with the contents of 'somefile.htmlinc'. We use this in the acl.html.in file, to pull the table of permissions for each libvirt object. This table is autogenerated from the enums in src/access/viraccessperms.h by the genaclperms.pl script. newapi.xsl is modified so that the list of permissions checks shown against each API will link to the description of the permissions in acl.html Signed-off-by: Daniel P.

[libvirt] [PATCH v2 0/9] Support qemu-system-arm vexpress-a9
by Cole Robinson 31 Aug '13

31 Aug '13

This series adds the bits needed to kick of a qemu-system-arm -machine vexpress-a9 guest. vexpress-a15 likely works as well but is untested. Patches 1-3 are related bugfixes/improvements. Patch 7 adds disk bus=sd, which is often the only way to specify storage for ARM boards. Patch 9 adds virtio-mmio address support, which enables virtio for ARM vexpress machine types. The rest are mostly about fixing CLI generations. Unfortunately qemu ARM boards don't quite work like x86 where we can mix and match devices, so -device is out of the picture (for non-virtio), meaning we have to fall back to CLI infrastrucure like -net nic and -serial. v2: Rebased series Drop patches applied with Laine's series Add patch 1 and 3 Clarify caveats in a few patch descriptions Cole Robinson (9): qemu: Set QEMU_AUDIO_DRV=none with -nographic qemu: Only setup vhost if virtType == "kvm" domain_conf: Add default memballon in PostParse callbacks qemu: Don't add default memballoon device on ARM qemu: Fix adding specifying char devs for ARM qemu: Don't try to allocate PCI addresses for ARM domain_conf: Add disk bus=sd, wire it up for qemu qemu: Fix networking for ARM guests qemu: Support virtio-mmio transport for virtio on ARM

[libvirt] [PATCH] Change way we fake dbus method calls
by Daniel P. Berrange 30 Aug '13

30 Aug '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> Ubuntu libdbus.so links with -Bsymbolic-functions, which means that we can only LD_PRELOAD functions that we directly call. Functions which libdbus.so calls internally can not be replaced. Thus we cannot use dbus_message_new_error or dbus_message_new_method_return Signed-off-by: Daniel P.

[libvirt] [PATCHv3 0/6] virsh: More intelligent auto-completion
by Tomas Meszaros 30 Aug '13

30 Aug '13

Hi, this patch series is a prototype for my GSoC project (Michal Privoznik is my mentor). I'm working on virsh auto-completion, trying to make it more "intelligent". At this stage, prototype is capable of command and option completion. Three completer functions are currently implemented so you can test it. If it turns out that this prototype is good enough, I will implement more completer functions. --- v3: * vshReconnect() is now called only when we reach the point that completion is being attempted on commands that needs connection * moved all .completer intializations into the 4/6, 5/6 and 6/6 v2: https://www.redhat.com/archives/libvir-list/2013-August/msg00992.html v1: https://www.redhat.com/archives/libvir-list/2013-August/msg00371.html Tomas Meszaros (6): virsh: C99 style for info_domfstrim and opts_lxc_enter_namespace virsh: Add vshCmdCompleter and vshOptCompleter virsh: Improve readline generators and readline completion virsh: Add vshDomainCompleter virsh: Add vshSuspendTargetCompleter virsh: Add vshRebootShutdownModeCompleter .gnulib | 2 +- tools/virsh-domain-monitor.c | 32 ++- tools/virsh-domain.c | 248 +++++++++++++++++----- tools/virsh-snapshot.c | 45 +++- tools/virsh.c | 480 +++++++++++++++++++++++++++++++++++++++++-- tools/virsh.h | 11 + 6 files changed, 725 insertions(+), 93 deletions(-) -- 1.8.3.1

[libvirt] [PATCH V2] Use loop-control to allocate loop device.
by Ian Main 30 Aug '13

30 Aug '13

This patch changes virFileLoopDeviceOpen() to use the new loop-control device to allocate a new loop device. If this behavior is unsupported we fall back to the previous method of searching /dev for a free device. With this patch you can start as many image based LXC domains as you like (well almost). Fixes bug https://bugzilla.redhat.com/show_bug.cgi?id=995543 V2: - Modified to use a dedicated error return for loop-control allocation function. - Only do fallback if /dev/loop-control does not exist, otherwise return error.

[libvirt] [RFC]Libvirt Wireshark Dissector
by Yuto KAWAMURA 30 Aug '13

30 Aug '13

Hi libvirt developers, I would like to ask you to review the dissector of libvirt RPC protocol which I've been developing on project of Google Summer of Code 2013[1][2][3]. It can add support for dissecting libvirt RPC protocol packet which communicate via TCP socket to Wireshark. This feature was presented by Michal Privoznik year before last[4]. But it did only support dissecting packet headers. This time I enhanced that dissector to support dissecting packet payload. Furthermore, I provide code generator of dissector. So you can get fresh build of dissector from libvirt RPC specification file at any version you like. Now it is available to build and install dissector from repository[3]. Only you need to do is: git clone https://github.com/kawamuray/libvirt-wireshark-dissector.git cd libvirt-wireshark-dissector autoreconf --install ./configure && make sudo make install Above commands only install a single shared object: $(dirname `which wireshark`)/../lib/wireshark/plugins/<wireshark version>/libvirt.so . After rebooting wireshark(or tshark), your wireshark have support for dissecting libvirt RPC packet. Please make sure your libvirtd is listening on port 16509(default libvirtd port) and connect to libvirtd using TCP socket(e.g. qemu+tcp:///system). You can also try the feature; generate dissector from your libvirt source tree by adding few options to ./configure. Please see README and ./configure --help output for more detail. Please try and review it. Any comments, reviews and patches for dissector code, generator code and usability are welcome.
