[libvirt] [PATCH] [Build-breaker : 1.2.12] Suppress compilation without dbus headers
by Prerna Saxena 26 Jan '15

26 Jan '15

Hi, While testing 1.2.12 rc2 on Powerpc, Fedora 21, I hit a bunch of build failures in absence of dbus-devel : src/util/virsystemd.c:284:17: note: in expansion of macro 'STREQ_NULLABLE' if (STREQ_NULLABLE("org.freedesktop.DBus.Error.UnknownMethod", ^ .... src/util/virsystemd.c:288:17: error: implicit declaration of function 'dbus_error_free' [-Werror=implicit-function-declaration] dbus_error_free(&error); Found that this was because commit 318df5a05 needs Dbus libraries for compilation, and configure didnt mark "with_dbus" to be mandatory. In this case, the compilation itself failed in a much uglier fashion on my system where dbus-devel was absent. The following patch introduces a compile error when dbus-devel is absent, so that the build itself proceeds later without cryptic errors. This has also been reported on the list : https://www.redhat.com/archives/libvir-list/2015-January/msg00641.html >From 8c4f583b6bb47ca41866ff884af0cd55487f047d Mon Sep 17 00:00:00 2001 From: Prerna Saxena <prerna(a)linux.vnet.ibm.com> Date: Sun, 25 Jan 2015 05:35:23 -0600 Subject: [PATCH] Build: Fix dbus m4 macro to correctly flag it as a required dependency. Commit 318df5a needs dbus headers to compile. However, this package is listed as optional, and so this breaks libvirt compilation on systems that lack the relevant devel files. This patch does not allow ./configure to proceed if dbus-devel is absent.

[libvirt] [PATCH] conf: Disallow emulatorpin when numatune's in effect
by Michal Privoznik 26 Jan '15

26 Jan '15

https://bugzilla.redhat.com/show_bug.cgi?id=1170492 In one of our previous commits (dc8b7ce7) we've obsoleted <cputune/> in favor of <numatune/> and others. If old element was passed it was basically ignored and interesting settings were copied from the new one. Well with one exception we'd forgotten about: emulatorpin. Imagine that domain is configured as follows: <vcpu placement='static' current='2'>6</vcpu> <cputune> <emulatorpin cpuset='1-3'/> </cputune> This is perfectly valid as only old style elements are used. However, adding new style elements messes up the XML: <vcpu placement='auto' current='2'>6</vcpu> <cputune> <emulatorpin cpuset='1-3'/> </cputune> <numatune> <memory mode='strict' placement='auto'/> </numatune> Since <numatune/> is auto, <vcpu/> becomes auto as well. However in that case we can't guarantee that emulator will be pinned onto selected nodes.

[libvirt] Missing libxl_device_nic settings

Hi, I was trying to pass ip address to scripts/vif-bridge by putting <ip address=""/> in guest config xml file, however, I found that libxlMakeNic(which located in libxl/libxl_conf.c:956) doesn't set x_nic->ip. So I patched myself but I'm not so sure about VIR_DOMAIN_NET_TYPE_ETHERNET. It seems like vif-route, correct?

[libvirt] Entering freeze for libvirt-1.2.12
by Daniel Veillard 24 Jan '15

24 Jan '15

As planned I tagged the release candidate 1 in git and pushed signed tarballs and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work fine for me, but my testing is limited. Give it a try especially on other architectures or OSes. Plan is to release an rc2 by the dn of the week and the final next Tuesday assuming everythings goes smoothly ! thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] libvirt domXML -> libxl_domain_config conversion testing
by Jim Fehlig 24 Jan '15

24 Jan '15

Hi All, I've been attempting to revive the libvirt domXML -> libxl_domain_config tests originally started by Daniel all the way back in May! https://www.redhat.com/archives/libvir-list/2014-May/msg01102.html In a reply to patch5 of the series, Ian Campbell noted that the doc produced by libxl_domain_config_to_json() may change as new config is added, defaults changed, etc. Some suggestions for coping with this included 1. json template files per libxl version 2. a new API in libvirt's json toolbox to compare json docs (with ability to control the comparison, e.g. ignore certain content) 3. make use of new functionality in Xen 4.5 such as libxl_domain_config_from_json() and libxl_domain_config_compare() Option 1 is simple-minded. Option 2 is an improvement, but a growing list of content must be ignored as additions/changes are made to the libxl_domain_config object. (Example of ignored content in this discussion - https://www.redhat.com/archives/libvir-list/2014-September/msg00627.html) In some cases, we might actually want to test some of the new content instead of ignoring it. Option 3 is promising, but doesn't help with Xen versions 4.2-4.4. Also, 4.5 is missing libxl_domain_config_compare(). After a bit of hacking on a combination of 2 and 3, I'm reconsidering 1 :-). At least for Xen 4.2-4.5. It's a simple solution that doesn't prevent testing new content in the libxl_domain_config object. Going forward, I could work on libxl_domain_config_compare() for xen-unstable/4.6, and then use option 3 to stop the template bloom. Any thoughts on this approach? Smarter options? Regards, Jim
