[libvirt] [PATCH 00/15] NEWS: Plenty of fixes and improvements
by Andrea Bolognani 14 Oct '15

14 Oct '15

Oh boy, where to start :) Patch 01 fixes the XSLT stylesheet used to generate the plain text NEWS file from docs/news.html.in. This has been broken for at least two years, based on the oldest release archive available on the website. Patches 02-05 clean up some very simple mistakes. Patches 06-09 are the juicy bits: very old entries were not as tidy as recent ones, so I went through them and polished them up to bring them up to standard. It would be great if someone who was around from the early days, ideally DV, could go over patch 09 in particular, since categorizing old changes I know barely nothing about is by definition prone to error. Patches 10-15 go over everything one last time for that extra shiny finish. Cheers. PS: Patch 07 contains an awfully long line that git-send-email warns me about. I'll try to sent it anyway, but if it doesn't make it to the list that's probably the reason.

[libvirt] cpu affinity, isolcpus and cgroups
by Henning Schild 14 Oct '15

14 Oct '15

Hi, i am currently looking into realtime VMs using libvirt. My first starting point was reserving a couple of cores using isolcpus and later tuning the affinity to place my vcpus on the reserved pcpus. My first observation was that libvirt ignores isolcpus. Affinity masks of new qemus will default to all cpus and will not be inherited from libvirtd. A comment in the code suggests that this is done on purpose. After that i changed the code to use only the available cpus by default. But taskset was still showing all 'f's on my qemus. Then i traced my change down to sched_setaffinity assuming that some other mechanism might have reverted my hack, but it is still in place. Libvirt is setting up cgroups and now my suspicion is that cgroups and taskset might not work well together. > /sys/fs/cgroup/cpu/machine.slice/machine-qemu\x2dvm1.scope/vcpu0# > cpuacct.usage_percpu > 247340587 50851635 89631114 23383025 412639264 1241965 55442753 19923 > 14093629 15863859 27403280 1292195745 82031088 53690508 135826421 > 124915000 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Looks like the last 16 cores are not used. But if i use taskset to ask for the affinity mask i get all 32 cpus. > taskset -p `cat tasks` > pid 12905's current affinity mask: ffffffff I know that is not strictly libvirt but also a kernel question, still you guys are probably able to point me to what i am missing here. > Linux 3.18.11+ #4 SMP PREEMPT RT regards, Henning

[libvirt] [PATCH RFC 0/7] libxl: domain statistics support
by Joao Martins 14 Oct '15

14 Oct '15

Hey Jim, This series bring support for various statistics about domains regarding CPU, Memory, Network Interfaces and BlockStats. Not all of the statistics are implemented: qdisk support is missing in this series and some of the memory statistics aren't available. With this series we further implement 7 more functions of libvirt APIs. It is organized as follows: * Patch 1, 2: implements cpu/memory statistics. * Patch 3, 4: implements (netback) network statistics and VBD block statistics. QDisk will follow up in a separate series regarding QEMU monitor integration. * Patch 5: implement fetching all domain statistics * Patch 6, 7: implements Job information. Overall it looks big but 70% of the patch is due to #4 and #5 but doesn't add necessarily more complexity to the driver I believe. Patch #6 and #7 are of special importance because GetJobInfo and GetJobStats are now used in Openstack Kilo to monitor live-migration progress. This two patches together with an earlier series [0] I sent before let us sucessfully live-migrate with Openstack Kilo. Further with this series we get to support nova diagnostics. Tested this series on 4.4.3 and 4.5 setups plus Openstack Kilo. Any comments or suggestions are welcome, Thanks!
