[libvirt] [python] WIP-FYI: mypy annotations for libvirt-python
by Philipp Hahn 20 Apr '20

20 Apr '20

Hello, Maybe you already have heads about mypy <http://mypy-lang.org/>, which "is an experimental optional static type checker for Python that aims to combine the benefits of dynamic (or "duck") typing and static typing". I started to write a manual annotation file for the Python binding of libvirt. I've attached my current version, so others can benefit from it, too. It is far from complete, but it already helped my to find some errors in my code. (My latest version is also available at <https://github.com/univention/typeshed/blob/libvirt/third_party/2and3/libvi…>) Long-term it probably would be better to teach the Python binding "generator.py" to add the type information (PEP 484 <https://www.python.org/dev/peps/pep-0484/>) directly into the generated "libvirt.py" file, but that's for another day. If someone else is interested in helping with that, please feel free to get in contact. Philipp -- Philipp Hahn Open Source Software Engineer Univention GmbH be open.

[libvirt-ci PATCH] lcitool: Don't set root shell
by Andrea Bolognani 20 Apr '20

20 Apr '20

Being able to log in as root is critical to recover from failures, so using bash might not always be the best idea: this is especially true for FreeBSD, where bash is installed via ports and might break on update from time to time, rendering the system inaccessible without jumping through additional hoops.

[libvirt PATCH 00/10] vbox: update to support newer versions and drop eol versions
by Daniel P. Berrangé 20 Apr '20

20 Apr '20

This is the bare minimum patches required to let libvirt compile with the latest virtualbox SDK for 6.0 and 6.1. Since I do not use virtualbox this is compile tested only. This will at least give users something to try and provide feedback on. In addition currently EOL versions of virtualbox are dropped. Daniel P.

[PATCH 0/2] Include lease time option into DHCP settings
by Julio Faracco 20 Apr '20

20 Apr '20

This series is based on latest series from Alberto. It includes a new entry called <leasetime/> under <dhcp/> scope to add a default lease time for range and host options for dnsmasq. There is no point to configure both separately. If they are defined (range and/or host), they should have the same lease time value. This series includes some test cases to cover lease time XML syntax also.

[PATCH] Add 'permissive' option for PCI devices

From: Simon Gaiser <simon(a)invisiblethingslab.com> By setting the permissive flag the guest access to the PCI config space is not filtered.
