Release of libvirt-9.7.0
by Jiri Denemark 01 Sep '23

01 Sep '23

The 9.7.0 release of both libvirt and libvirt-python is tagged and signed tarballs and source RPMs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * New features * qemu: basic support for use of "VFIO variant" drivers A VFIO variant driver is a device-specific driver that can be used in place of the generic vfio-pci driver, and provides extra functionality to support things like live migration of guests with vfio-assigned devices. It can currently be used by: 1) setting ``managed='no'`` in the XML configuration for the device 2) pre-binding the variant driver using the ``--driver`` option of ``virsh nodedev-detach``. * Bug fixes * qemu: Various fixes to firmware selection The changes made to firmware selection in libvirt 9.2.0 have unfortunately introduced a number of regressions. All known issues in this area have now been resolved. Enjoy. Jirka

[libvirt PATCH v2 0/6] external snapshot revert fixes
by Pavel Hrdina 01 Sep '23

01 Sep '23

This fixes reverting external snapshots to not error out in cases where it should work and makes it correctly load the memory state when reverting to snapshot of running VM. Last patch is not part of the fix, it is alternative solution to remove the capability as we are close to releasing libvirt 9.7.0 in case the code fixing reverting snapshots is considered too complex. This v2 limits the impact only to snapshot code and no longer changes anything in qemu_saveimage except for exporting one function and one enum.

Sunset libvirt-snmp?
by Michal Prívozník 01 Sep '23

01 Sep '23

It's been a while since libvirt-snmp was actively developed. Now it receives only libvirt-ci related commits. The code compiles with net-snmp-5.9.3 but the freshly released net-snmp-5.9.4 [1] breaks compilation [2]. Now, libvirt-snmp has this crazy architecture, where some sources are manually generated from src/LIBVIRT-MIB.txt, then edited (added code to talk to libvirt) and then added to git. This is labor extensive and since I don't think libvirt-snmp is actually used I'd like to sunset it. According to repology [3] only Gentoo (and its clones) has the latest version (released ~5 years ago). And I doubt it has any real users there. Thoughts? 1: https://sourceforge.net/projects/net-snmp/files/net-snmp/5.9.4/ 2: https://bugs.gentoo.org/show_bug.cgi?id=912582 2: https://repology.org/project/libvirt-snmp/versions Michal

[PATCH] virsh: Fix net-desc --config output
by K Shiva Kiran 01 Sep '23

01 Sep '23

Fixes the following bug: Command: `net-desc --config [--title] my_network` Expected Output: Title/Description of persistent config Output: Title/Description of live config This was caused due to the usage of a single `flags` variable in `virshGetNetworkDescription()` which ended up in a wrong enum being passed to `virNetworkGetMetadata()` (enum being that of LIVE instead of CONFIG). Although the domain object has the same code, this didn't cause a problem there because the enum values of `VIR_DOMAIN_INACTIVE_XML` and `VIR_DOMAIN_METADATA_CONFIG` turn out to be the same (1 << 1), whereas they are not for network equivalent ones (1 << 0, 1 << 1).
