[libvirt] [PATCH] configure: Prefer /usr/bin over /bin for numad
by Guido Günther 20 Nov '16

20 Nov '16

On Debian systems numad gets installed to /usr/bin. However some people use usrmerge[0] which links /bin to /usr/bin. By changing the lookup order we make sure the daemon is always found in /usr/bin (with or without usrmerge installed). This allows packages built on systems with usrmerge to run on systems without usrmerge which would otherwise fail since /bin/numad would be hardcoded into libvirt.

[libvirt] [PATCH RESEND v3.2 00/10] Implementation of QEMU vhost-scsi
by Eric Farman 19 Nov '16

19 Nov '16

[NOTE: Resending after a week, and rebased to apply to master after last week's application of commit 22d94ca4] This patch series provides a libvirt implementation of the vhost-scsi interface in QEMU. As near as I can see, this was discussed upstream in July 2014[1], and ended in a desire to replace a vhost-scsi controller in favor of a hostdev element instead[2].

[libvirt] [PATCH v2 00/19] Redo website layout and branding
by Daniel P. Berrange 19 Nov '16

19 Nov '16

The current libvirt website design dates from 2008 and has not changed significantly since. Compared to contemporary open source project websites it looks pretty dated and cluttered. This series incrementally changes the website to have a completely new layout and branding. Since the original adobe illustrator files are long since lost, this series introduces a newly created variant of the libvirt logo with Inkscape as an SVG file. The libvirt logo used a specific font with angled tops to letters like "l", "b" and "t" - this is the "Overpass" font, made available by Red Hat under an open source font license. The re-branding makes use of webfont support so that we can use this font across the entire libvirt website for a consistent look. The colors of the website CSS now exactly match the colors used in the logo in most places. The bigger change is in the layout, with the huge left hand sitemap nav bar being removed to give more space to the main content. The front page now directly links to the key pages that were shown to be highly visited in the apache web logs. Most of the rest of the links are now available from the "docs.html" page linked from "Learn" in the top nav bar. Another key change is that the download page now covers all language bindings, test suites, docs released by the project, not merely the core C library. Finally a new page "contribute.html" is added as the source of information useful to people wishing to get involved in the libvirt project. View the new site here v2: https://berrange.fedorapeople.org/libvirt-new-website-v2/ v1: https://berrange.fedorapeople.org/libvirt-new-website/ Changed in v2: - Fix use of monospace font for code/pre blocks - Set max page width to 60em, to avoid body content getting really long lines on wide monitors - Extend footer links to include email and irc links on all pages - Use the normal weight Overpass font for body content - Re-create logos to avoid anti-aliasing by inkscape for cripser look - Add some content to the XML format page - Misc typos - Fix hiding of 'home' text in top banner logo - Provide improved SVG files for logo and PNG rendered versions in standard sizes - Replace 'made with libvirt' logo with a new 'libvirt powered' logo on apps.html page Daniel P. Berrange (19): docs: use overpass font for website docs: add master SVG for libvirt logo docs: switch to new website banner docs: redo style of front page docs: provide new style logos for the apps page docs: add footer to all pages docs: simplify style for headers docs: add page describing contribution to libvirt docs: add three core links in the header bar docs: remove todo page docs: remove related links page Revert "syntax-check: Enforce <code> inside <dt> elements" docs: rewrite content on front page to be more useful docs: expand downloads page to cover all modules docs: add some improved styling to contact page docs: fill out docs page with useful links docs: remove navigation sidebar from pages docs: remove outdated or duplicated content docs: add some content to the XML format main page cfg.mk | 20 +- docs/404.html.in | 5 -

[libvirt] [PATCH] qemu: Redefine the "unlimited" memory limits one more time
by Viktor Mihajlovski 19 Nov '16

19 Nov '16

With kernel 3.18 (since commit 3e32cb2e0a12b6915056ff04601cf1bb9b44f967) the "unlimited" value for cgroup memory limits has changed once again as its byte value is now computed from a page counter. The new "unlimited" value reported by the cgroup fs is therefore 2**51-1 pages which is (VIR_DOMAIN_MEMORY_PARAM_UNLIMITED - 3072). This results e.g. in virsh memtune displaying 9007199254740988 instead of unlimited for the limits. This patch deals with the rounding issue by scaling the byte values reported by the kernel and the PARAM_UNLIMITED value to page size and comparing those. See also libvirt commit 231656bbeb9e4d3bedc44362784c35eee21cf0f4 for the history for kernel 3.12 and before.

[libvirt] [PATCH] Fix scheduler support check
by Martin Kletzander 18 Nov '16

18 Nov '16

Commit 94cc577807ba tried fixing build on systems that did not have SCHED_BATCH or SCHED_IDLE defined. But instead of changing it to conditional support, it rather completely disabled the support for setting any scheduler. Since then, such old systems are not supported, but rather than reverting that commit, let's change that to the conditional support. That way any addition to the list of schedulers can follow the same style so that we're consistent in the future. Signed-off-by: Martin Kletzander <mkletzan(a)redhat.com> --- Notes: Of course there are various ways how to address that, I went with case. Also defining undefined SCHED_* to -1 makes some gnulib syntax-check go haywire. src/util/virprocess.c | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) diff --git a/src/util/virprocess.c b/src/util/virprocess.c index 718c4a2664e1..39d6b30c40f2 100644 --- a/src/util/virprocess.c +++ b/src/util/virprocess.c @@ -1183,7 +1183,7 @@ virProcessExitWithStatus(int status) exit(value); } -#if HAVE_SCHED_SETSCHEDULER && defined(SCHED_BATCH) && defined(SCHED_IDLE) +#if HAVE_SCHED_SETSCHEDULER static int virProcessSchedTranslatePolicy(virProcessSchedPolicy policy) @@ -1196,10 +1196,18 @@ virProcessSchedTranslatePolicy(virProcessSchedPolicy policy) return SCHED_BATCH; case VIR_PROC_POLICY_IDLE: +# ifdef SCHED_IDLE return SCHED_IDLE; +# else + return -1; +# endif case VIR_PROC_POLICY_FIFO: +# ifdef SCHED_FIFO return SCHED_FIFO; +# else + return -1; +# endif case VIR_PROC_POLICY_RR: return SCHED_RR; @@ -1225,6 +1233,13 @@ virProcessSetScheduler(pid_t pid, if (!policy) return 0; + if (pol < 0) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("Scheduler '%s' is not supported on this platform"), + virProcessSchedPolicyTypeToString(policy)); + return -1; + } + if (pol == SCHED_FIFO || pol == SCHED_RR) { int min = 0; int max = 0; -- 2.10.2
