[libvirt] [PATCH] util: remove some no-op thread functions
by Daniel P. Berrangé
Neither virThreadInitialize or virThreadOnExit do anything since we
dropped the Win32 threads impl, in favour of win-pthreads.

[libvirt] [PATCHv2] maint: Use flake8 to check python code
by Shi Lei
Replace 'sc_prohibit_semicolon_at_eol_in_python' with generic 'sc_flake8' rule
to check python code style.
Now 'sc_flake8' just check the error E703: 'statement ends with a semicolon'.
In future, we could use '--select' to introduce more rules.
Signed-off-by: Shi Lei <shi_lei(a)massclouds.com>
---
v1: https://www.redhat.com/archives/libvir-list/2019-September/msg00501.html
since v1:
- Use the return-value from flake8 directly for 'sc_flake8'.
- Add the option '--show-source' to be more helpful for developers.
- Set checking for 'flake8' as a soft requirement.

[libvirt] Call for volunteers: LWN.net articles about KVM Forum talks
by Stefan Hajnoczi
Hi,
LWN.net is a popular open source news site that covers Linux and other
open source communities (Python, GNOME, Debian, etc). It has published
a few KVM articles in the past too.
Let's raise awareness of QEMU, KVM, and libvirt by submitting articles covering
KVM Forum.
I am looking for ~5 volunteers who are attending KVM Forum to write an article
about a talk they find interesting.
Please pick a talk you'd like to cover and reply to this email thread.
I will then send an email to LWN with a heads-up so they can let us know
if they are interested in publishing a KVM Forum special. I will not
ask LWN.net for money.
KVM Forum schedule:
https://events.linuxfoundation.org/events/kvm-forum-2019/program/schedule/
LWN.net guidelines:
https://lwn.net/op/AuthorGuide.lwn
"Our general guideline is for articles to be around 1500 words in
length, though somewhat longer or shorter can work too. The best
articles cover a fairly narrow topic completely, without any big
omissions or any extra padding."
I volunteer to cover Michael Tsirkin's "VirtIO without the Virt -
Towards Implementations in Hardware" talk.
Thanks,
Stefan

This is technically a v2 of:
https://www.redhat.com/archives/libvir-list/2019-September/msg00281.html
It implements what Jano suggested - use dbus-vmstate capability to
decide if slirp-helper is used.

[libvirt] [RFC] quirks of interface target device name
by Nikolay Shirokovskiy
Hi, all
I recently discovered that <target dev=''/> input is allowed[*]
by qemu driver's defineXML for <interface> element. On start it will
turn into 'tap<N>'. At the same time empty value is not allowed by
schema. This name is generated by kernel on linux.
I wonder how to deal with this.
1. Fix schema to allow empty value for dev attribute. Additionally fix
migrating to clear out this autogenerated name. This way we have 2
options to autogenerate dev name. First as described above. Second
is by ommiting target element. The naming will be 'vnet<N>' in the
latter case. Having these 2 options looks redundant.
2. Don't allow to start domains with such configuration. We can not
fail definition because disappearing VMs on libvirt update looks
too unpleasant. This way we don't have two different set of
autogenerated names. This can even go unnoticed given we fail
such starts anyway after [1] (which is fixed by [*]). [1] is
commited on 2018 Jul 23 and released in 4.6.0. However Centos 7
is based on 4.5.0 and virNetDevTapCreate has logic to copy
generated tap name from kernel like since the beginning (I managed
to follow the history to 2011).

[libvirt] [PATCH 0/2] Fix systemd socket activation for systemd < v227
by Michael Chapman
A couple of bugs were encountered using socket activated libvirtd on
CentOS 7:
- When resolving a tls_port/tcp_port from the config file (needed even
when using socket activation on systemd < v227), the port endianness
was incorrect.
- The wrong name was used when checking whether libvirtd-tls.socket
was passed to libvirtd, leading to this socket not being properly
registered.
