by Pavel Hrdina
I'm happy to announce the release of libvirt-dbus 1.3.0.
libvirt-dbus wraps libvirt API to provide high-level object-oriented
API better suited for dbus-based applications.
You can download it here:
https://libvirt.org/sources/dbus/libvirt-dbus-1.3.0.tar.xz
* New features
- Support for all relevant interface APIs up to libvirt 3.0.0
* Bug fixes
- Storage volumes and with special characters in the name are now correctly listed
* Build-system improvements
- Detect flake8 automatically
- Install daemon under @sbindir@
- Fix version check for dependencies
Thanks everybody who contributed!

[Libvirt-announce] Release of libvirt-5.0.0
by Daniel Veillard
Hi all,
as planned I just tagged the new release in git, and pushed signed tarball
and rpms to the usual place:
ftp://libvirt.org/libvirt/
I also pushed the python bindings, identical to 4.10 with just the versioning
bump, you can find them at:
ftp://libvirt.org/libvirt/python/
This release includes new features, but also remove the old apparently unused
UML driver support. There is also a rather large set of improvements:
New features:
- Xen: Add support for openvswitch
The libxl driver now supports virtual interfaces that connect to an
openvswitch bridge, including interfaces with VLAN tagging and trunking
configuration.
- qemu: Report whether KVM nesting is available
Running nested KVM guests requires specific configuration steps to be
performed on the host; libvirt will now report in the host capabilities
whether KVM nesting support is available.
Removed features:
- Drop UML driver
The UML driver was unmaintained and not tested for quite some time now.
Worse, there is a bug that causes it to deadlock on some very basic
operations (e.g. dumping domain XML). These facts make us believe no
one uses it.
Improvements:
- qemu: Add support for ARMv6l guests
- Support more NVDIMM configuration options
Introduce more configuration options. For the source element, add the
'alignsize' and 'pmem' subelements. For the target element, add the
'readonly' subelement.
- cpu: Add support for "stibp" x86_64 feature
Add cpu flag stibp (Single Thread Indirect Branch Predictors) to
prevent indirect branch predictions from being controlled by the
sibling Hyperthread.
- libxl: Handle external domain destroy
Historically, if a domain was destroyed using xl rather than through
libvirt APIs, libvirt would not be aware of the fact and keep
considering it as running. This is no longer the case.
- Start selecting the first available DRI device for OpenGL operations
If OpenGL support is needed (either with SPICE gl enabled or with
egl-headless), libvirt is now able to pick the first available DRI
device for the job. At the same time, this improvement is also a bugfix
as it prevents permission-related issues with regards to our mount
namespaces and the default DRI render node's permissions which would
normally prevent QEMU from accessing such a device.
- qemu: Add support for postcopy-requests migration statistics
The virDomainJobInfo can get number page requests received from the
destination host during post-copy migration.
Bug fixes:
- lxc: Don't forbid interfaces with type=direct
Such interfaces are supported by lxc and should be allowed.
- qemu: Fully clean up RNG devices on detach
Some RNG device types, such as those using EGD, might need extra clean
up on the host in addition to removing the guest-side device.
Thanks everybody for your help toward this release, be it with patches
reviews, bug description, documentation and localizations !
As a reminder, the next release is scheduled at the end of February,
in the meantime, enjoy the new release !
Daniel

[Libvirt-announce] Entering freeze for libvirt-5.0.0
by Daniel Veillard
As planned I tagged the RC1 in git and pushed signed tarball and rpms to
the usual place:
ftp://libvirt.org/libvirt/
I didn't see the 5 patches from Laine in git at that point but those seems
to be bug + portability fixes anyway so it should still be possible to have
them in say before rc2.
Seems to be working fine in my limited testing, and CI seems to be mostly
green excepot a few edge cases https://ci.centos.org/view/libvirt/ so that's
looking good to me, but as usual it's good to exercice the RCs in various
condition to make sure we didn't introdue regressions on some platforms.
I plan on RC2 release during the week-end and then if everything goes well
push 5.0.0 out on Tuesday for Jan 15 deadline,
thanks in advance for giving it some testing !
