ANNOUNCE: libvirt-dbus 1.4.0 released
by Pavel Hrdina
I'm happy to announce the release of libvirt-dbus 1.4.0.
libvirt-dbus wraps libvirt API to provide high-level object-oriented
API better suited for dbus-based applications.
https://libvirt.org/sources/dbus/libvirt-dbus-1.4.0.tar.xz
* New features
- Support for all relevant domain snapshot APIs
* Build-system changes
- Converted to meson/ninja build system
* Documentation
- Everything was converted to reStructuredText
Thanks everybody who contributed!

Entering freeze for libvirt 6.3.0
by Daniel Veillard
We are getting close to the end of the month, so I tagged RC1 in git
and pushed signed source tarball and rpms to the usual place:
https://libvirt.org/sources/
Seems to work fine in my very limited testing, CI seems green except for a
couple of mingw tests, so that looks good from a distance.
Please give it some testing, RC2 should land on Thursday, and then if
everything looks fine I could push the final version over the coming week-end.
Stay safe, please test it,
thanks,
Daniel

Release of libvirt-6.2.0
by Daniel Veillard
Mea-culpa I forgot to push RC2 on Tuesday, rather than pushing the
release off by 2 more days, I decided to push the release today to stay
on schedule. As a result 6.2.0 is out, tagged in git and source tarball
and rpm are available at the usual place:
https://libvirt.org/sources/
I also pushed a release of the python binding with minimal changes that
can be found at:
https://libvirt.org/sources/libvirt/
New features:
- qemu: NVDIMM support for pSeries guests
QEMU 5.0 implements NVDIMM memory support for pSeries guests. This is
done by adding an 'uuid' element in the memory XML, which can either be
provided in the XML or, if omitted, generated automatically.
- qemu: Add virtiofs support
This feature, introduced in QEMU 4.2, is a more modern alternative to
virtio-9p, which is exposed through the same <filesystem/> element.
- admin: Support reloading TLS certificates
After renewing TLS certificates, it was usually necessary to restart
libvirtd for the new ones to be loaded: now the same result can be
obtained without restarting the daemon by using virt-admin
server-update-tls.
Removed features:
- Removed support for INI style of comments
With switching of our internal code to GLib, parsing of client
authentication config files is handed over to GLib which does not
support INI style of comments starting with a semicolon (;). Use number
sign (#) instead.
* Improvements
- qemu: Don't compare local and remote hostnames on migration
This check was introduced to prevent same-host migration, but did not
work as expected when multiple libvirtd instances were running on the
same host but in different containers. With this release, the host UUID
(which should be unique to the container) is checked instead.
- qemu: Use per-VM event loops
Instead of using a single even loop to process communication with the
QEMU monitor and guest agent, create a separate one for each VM. This
helps with scalability and prevents scenarios where a single
malfunctioning VM could affect all those running on the same host.
- qemu: Support migration with SLIRP helper interface
With QEMU 5.0, a new D-Bus backend allows migration of external
processes. When needed, libvirt will start a per-vm D-Bus bus, and
migrate the slirp-helper along with QEMU.
Bug fixes:
- qemu: Open backing chain late for shallow block copy reusing external images
With introduction of -blockdev for QEMU storage configuration in
libvirt-5.10 we've started opening the backing chain of the
destination/mirror of a virDomainBlockcopy started with
VIR_DOMAIN_BLOCK_COPY_REUSE_EXT | VIR_DOMAIN_BLOCK_COPY_SHALLOW flags
when starting the job rather than when virDomainBlockJobAbort with
VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT is issued. For users depending on this
undocumented quirky pre-blockdev behaviour this caused a regression as
the backing chain could not be modified while the copy of the top image
was progressing due to QEMU image locking. Note that this fix also
requires qemu-5.0 while -blockdev is used starting from QEMU-4.2.
- Don't generate machine names containing dots
Even though the guest name containing dots is not a problem for libvirt
itself, we need to strip them out when registering with machined
because of the latter's requirements.
Thanks everybody who contributed to this release be it with
bug reports, fixes, reviews, documentation, etc ...
Enjoy the release, stay safe!
Daniel
