[libvirt] [RFC PATCH 0/5] qemu: drop command line parsing
by Peter Krempa 17 Jun '19

17 Jun '19

All the code is mostly outdated and does not really help in most cases. Since this was already proposed and I did not see anything against here are the patches. As a follow up I'll refactor and move the rest of qemu_parse_command.c once this is out of the way. you can fetch this by git fetch https://github.com/pipo/libvirt.git parse-command-delete Peter

[libvirt] [PATCH 00/19] Use '#pragma once' in headers
by Jonathon Jongsma 14 Jun '19

14 Jun '19

Hi all, I'm trying to get up to speed with libvirt code, so I decided to start out with a slightly "mindless" task. I grabbed the '#pragma once' task from https://wiki.libvirt.org/page/BiteSizedTasks. This series covers the first part of the conversion. I chatted with Daniel Berrange briefly on IRC before starting, and he suggested that I should try to keep patches under 100k, and maybe each driver's source files as a single patch. I had a bit of difficulty deciding where to split the src/conf/ and src/util/ directories. So some of the files with more changes ended up being single-file patches. I tried to combine some related source files into patches, but at a certain point I ran out of obvious files to combine, so I combined a bunch of smaller miscellaneous files into one larger patch. It may not be ideal, but it's the best I could come up with. Alternative suggestions welcome. I'll follow up with the remaining changes if this division looks acceptable.

[libvirt] [PATCH v2] qemu: fix pr-helper0 remain
by Jie Wang 13 Jun '19

13 Jun '19

If libvirt receive DISCONNECTED event and set prDaemonRunning to false, and qemuDomainRemoveDiskDevice is performing in the meantime. qemuDomainRemoveDiskDevice will return directly by prDaemonRunning check, so the pr-helper0 object will remain. In that case we should try harder and also kill the pr-helper process, so qemuProcessKillManagedPRDaemon could use the same treatment.

[libvirt] [PATCH] qemu: Add support for overriding max threads per process limit
by Jim Fehlig 12 Jun '19

12 Jun '19

Some VM configurations may result in a large number of threads created by the associated qemu process which can exceed the system default limit. The maximum number of threads allowed per process is controlled by the pids cgroup controller and is set to 16k when creating VMs with systemd's machined service. The maximum number of threads per process is recorded in the pids.max file under the machine's pids controller cgroup hierarchy, e.g. $cgrp-mnt/pids/machine.slice/machine-qemu\\x2d1\\x2dtest.scope/pids.max Maximum threads per process is controlled with the TasksMax property of the systemd scope for the machine. This patch adds an option to qemu.conf which can be used to override the maximum number of threads allowed per qemu process. If the value of option is greater than zero, it will be set in the TasksMax property of the machine's scope after creating the machine.

[libvirt] [PATCH] test_driver: implement virDomainGetLaunchSecurityInfo
