Release of libvirt-8.4.0

The 8.4.0 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 feedback. Your work is greatly appreciated. * New features * qemu: D-Bus display Libvirt is now able to setup a D-Bus display export, either with a private bus or in p2p mode. This display is available in QEMU 7.0.0. * qemu: ppc64 Power10 processor support Support for the recently released IBM Power10 processor was added. * qemu: Introduce ``absolute`` clock offset The ``absolute`` clock offset type allows to set the guest clock to an arbitrary epoch timestamp at each start. This is useful if some VM needs to be kept set to an arbitrary time for e.g. testing or working around broken software. * qemu: add qemu-vdagent channel This paravirtualized qemu vdagent channel can enable copy and paste between a guest and a VNC client. It is available in QEMU 6.1.0. * api: Add new APIs ``virDomainSaveParams`` and ``virDomainRestoreParams`` * ``virDomainSaveParams``: An alternative domain saving API, extends ``virDomainSaveFlags`` by adding parameters. * ``virDomainRestoreParams``: An alternative domain restoring API, extends ``virDomainRestoreFlags`` by adding parameters. * Bug fixes * Improve heuristics for computing baseline CPU models Both ``virConnectBaselineHypervisorCPU`` and ``virConnectBaselineCPU`` were in some cases computing the result using a CPU model which was newer than some of the input models. For example, ``Cascadelake-Server`` was used as a baseline for ``Skylake-Server-IBRS`` and ``Cascadelake-Server``. The CPU model selection heuristics was improved to choose a more appropriate model. Enjoy. Jirka
