Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* Improvements
* network: make networks with ``<forward mode='open'/>`` more useful
It is now permissable to have a ``<forward mode='open'>`` network that
has no IP address assigned to the host's port of the bridge. This
is the only way to create a libvirt network where guests are
unreachable from the host (and vice versa) and also 0 firewall
rules are added on the host.
It is now also possible for a ``<forward mode='open'/>`` network to
use the ``zone`` attribute of ``<bridge>`` to set the firewalld zone of
the bridge interface (normally it would not be set, as is done
with other forward modes).
* storage: Lessen dependancy on the ``showmount`` program
Libvirt now automatically detects presence of ``showmount`` during runtime
as we do with other helper programs and also the
``daemon-driver-storage-core`` RPM package now doesn't strongly depend on it
if the users wish for a more minimal deployment.
* Switch from YAJL to json-c for JSON parsing and formatting
The parser and formatter in the libvirt library, as well
as the parsers in the nss plugin were rewritten to use json-c
instead of YAJL, which is effectively dead upstream.
* Relax restrictions for memorytune settings
It should now be possible to use resctrl on AMD CPUs as well as Intel CPUs
when the resctrl filesystem is mounted with ``mba_MBps`` option.
* Bug fixes
* virsh: Fix script-friedly output of ``virsh list --uuid``
The script-friendly output of just 1 UUID per line was mistakenly replaced
by the full human-targetted table view full of redundant information
and very hard to parse. Users who wish to see the UUIDs in the tabular
output need to use ``virsh list --table --uuid`` as old behaviour was
reverted.
Note that this also broke the ``libvirt-guests`` script. The bug was
introduced in `v10.7.0 (2024-09-02)`_.
* network/qemu: fix some cases where ``device-update`` of a network
interface was failing:
* If the interface was connected to a libvirt network that was
providing a pool of VFs to be used with macvtap passthrough
mode, then *any* update to the interface would fail, even
changing the link state. Updating (the updateable parts of) a
macvtap passthrough interface will now succeed.
* It previously was not possible to move an interface from a Linux
host bridge to an OVS bridge. This (and the opposite direction)
now works.
* qemu: backup: Fix possible crashes when running monitoring commands during backup job
The qemu monitor code was fixed to not crash in specific cases when
monitoing APIs are called during a backup job.
* Fix various memleaks and overflows
Multiple memory leaks and overflows in corner cases were fixed based on
upstream issues reported.
* network: Better cleanup after disappeared networks
If a network disappeared while virtnetworkd was not running not all clean up
was done properly once the daemon was started, especially when only the
network interface disappeared. This could have in some cases resulted in
the network being shown as inactive, but not being able to start.
* qemu: Remember memory backing directory for domains
If ``memory_backing_dir`` is changed during the lifetime of a domain with
file backed memory, files in the old directory would not be cleaned up once
the domain is shut down. Now the directory that was used during startup is
remembered for each running domain.
Enjoy.
