Entering freeze for libvirt-6.7.0
by Jiri Denemark
I have just tagged v6.7.0-rc1 in the repository and pushed signed
tarballs and source RPMs to https://libvirt.org/sources/
The is the first release using meson and ninja which replaced autotools
and make so please give the release candidate some testing and in case
you find a serious issue which should have a fix in the upcoming
release, feel free to reply to this thread to make sure the issue is
more visible.
If you have not done so yet, please update NEWS.rst to document any
significant change you made since the last release.
Thanks,
Jirka

Release of libvirt-6.6.0
by Jiri Denemark
The 6.6.0 release of both libvirt and libvirt-python is tagged and
signed tarballs and source RPMs are available at
https://libvirt.org/sources/
https://libvirt.org/sources/python/
Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing any other feedback. Your work is
greatly appreciated.
* New features
* Allow configuring of ACPI NUMA HMAT
Libvirt allows configuring ACPI Heterogeneous Memory Attribute Table to
hint software running inside the guest on optimization.
* esx: Add a ``type`` attribute for mac addresses.
This attribute allows (when set to ``static``) ignoring VMWare checks of the
MAC addresses that would generate a new one if they were in its OUI
(00:0c:29).
* conf: add control over COW for storage pool directories
The storage pool code now attempts to disable COW by default on btrfs, but
management applications may wish to override this behaviour. This is now
possible via new ``cow`` element.
* Improvements
* esx: Change the NIC limit for recent virtualHW versions
Specifying a virtualHW version greater or equal to 7 (ESXi 4.0) will allow
you to use up to 10 NICs instead of 4 as it was previously.
* qemu: Support encrypted TLS keys for NBD disks
The secret key used for disks can now be encrypted similarly to TLS keys
used for migration, chardev and others.
* qemu: ``VIR_DOMAIN_EVENT_ID_BLOCK_THRESHOLD`` can now be registered for ``<mirror>``
The event can now be used also for block copy destinations by using the
index of the ``<mirror>`` image.
* qemu: consider available CPUs in ``vcpupin/emulatorpin`` output
This patch changes the default bitmap of ``vcpupin`` and ``emulatorpin``,
in the case of domains with static vcpu placement, all available CPUs
instead of all possible CPUs are returned making these APIs consistent with
the behavior of ``vcpuinfo``.
* Bug fixes
* virdevmapper: Don't use libdevmapper to obtain dependencies
When building domain's private ``/dev`` in a namespace, libdevmapper was
consulted for getting full dependency tree of domain's disks. However, this
meant that libdevmapper opened ``/dev/mapper/control`` which wasn't closed
and was leaked to QEMU. CVE-2020-14339
* qemu: Report correct ``index`` in ``VIR_DOMAIN_EVENT_ID_BLOCK_THRESHOLD``
Starting from libvirt 5.10 with QEMU 4.2 the
``VIR_DOMAIN_EVENT_ID_BLOCK_THRESHOLD`` event would report incorrect device
``index`` when reported for an image from the backing chain of a disk.
* qemu: Don't fail active layer block commit or block copy in certain cases
Starting from libvirt-6.5 an active layer block commit or a block copy could
fail if the same destination was used more than once.
* qemu: Don't change ownership of restore file
When restoring a domain from a file, Libvirt no longer changes its ownership.
* qemu: Set SPAPR TPM default to 2.0 and prevent 1.2 choice
The firmware (SLOF) on QEMU for ppc64 does not support TPM 1.2, so prevent
the choice of TPM 1.2 when the SPAPR device model is chosen and use a
default of '2.0' (TPM 2) for the backend.
* qemu: Do not set ``//cpu/@migratable`` for running domains
Libvirt release of 6.4.0 started to fill the default value for
``//cpu/@migratable`` attribute according to QEMU support. However, active
domains either have the migratable attribute already set or they were
started with older Libvirt which doesn't support the attribute.
Enjoy.
