[libvirt] [PATCH 0/4] Couple of allocation fixes

[libvirt] [PATCH 0/4] docs: Ship and install a few more files
by Andrea Bolognani 13 May '19

Our handling of documentation is far from perfect, and a few issues in particular are causing me quite a bit of grief on the Debian packaging side of things. This series takes care of the more pressing matters; I have further cleanups planned for later.

[libvirt] [PATCH RFC] network: Delay creating private chains until starting network
by Jim Fehlig 13 May '19

13 May '19

Automated performance tests found that network-centric workloads suffered a 20 percent decrease when the host libvirt was updated from 5.0.0 to 5.1.0. On the test hosts libvirtd is enabled to start at boot and the "default" network is defined, but it is not set to autostart. libvirt 5.1.0 introduced private firewall chains with commit 5f1e6a7d. The chains are created at libvirtd start, which triggers loading the conntrack kernel module. Subsequent tracking and processing of connections resulted in the performance hit. Prior to commit 5f1e6a7d the conntrack module would not be loaded until starting a network, when libvirt added rules to the builtin chains. Restore the behavior of previous libvirt versions by delaying the creation of private chains until the first network is started. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com> --- I briefly discussed this issue with Daniel on IRC and just now finding time to bring it to the list for broader discussion.

[libvirt] [PATCH] qemu: Fix regression with undefine --snapshots-metadata
by Eric Blake 10 May '19

10 May '19

In refactoring the snapshot code to prepare for checkpoints, I changed qemuDomainMomentDiscardAll to take a callback that would handle the cleanup of either a snapshot or a checkpoint, but failed to set the callback on one of the two snapshot callers. As a result, 'virsh undefine $dom --snapshots-metadata' crashed on a NULL function dereference.

[libvirt] Running libvirtd out of source directory connection reset error
by Peter P. 10 May '19

10 May '19

Hi all, I'm getting started with hacking around with libvirt and am trying to familiarize myself with launching and running an instance of libvirtd I built from source on Centos 7.6. Following the instructions from https://libvirt.org/compiling.html to launch my built versions of libvirtd and virsh, I get the following error with no other context when trying to start a domain using "virsh start mydomain": error: Cannot recv data: Connection reset by peer Despite this error, I am able to run commands list virsh list. Are there additional parameters needed to launch libvirtd or additional services I need to start up alongside it? Thanks, Peter

[libvirt] [PATCH RFC] iohelper: Introduces a small sleep do avoid hunging other tasks
by Leonardo Bras 10 May '19

10 May '19

While dumping very large VMs (over 128GB), iohelper seems to cause very intense IO usage on the disk, and it causes some processes (like journald) to hung, and depending on kernel configuration, to panic. This change creates a time window, after every 10GB written, so this processes can write to the disk, and avoid hunging.
