================ libvirt releases ================ This is the list of official releases for libvirt, along with an overview of the changes introduced by each of them. For a more fine-grained view, use the `git log`_. v7.3.0 (unreleased) =================== * **New features** * xen: Support domains with more than 4TB The xen driver now supports domains with more than 4TB of memory with xen >= 4.13. * qemu: add socket for virtiofs filesystems Libvirt now supports ``filesystem`` devices that connect to a ``virtiofsd`` daemon launched outside of libvirtd, via the ``socket`` attribute of the ``source`` element. * nodedev: Add ability to manage persistent mediated devices Persistent mediated devices can now be managed with libvirt. ``virNodeDeviceDefineXML()`` defines a new device, ``virNodeDeviceUndefine()`` removes an existing definition, and ``virNodeDeviceCreate()`` starts a device definition that is currently inactive. Corresponding virsh commands ``nodedev-define``, ``nodedev-undefine``, and ``nodedev-start`` were also added. ``nodedev-list`` only lists active devices by default. Inactive device definitions can be shown with the new ``--inactive`` and ``--all`` flags. * **Improvements** * **Bug fixes** v7.2.0 (2021-04-01) =================== * **New features** * qemu: Implement domain memory dirty rate calculation API New API ``virDomainStartDirtyRateCalc()`` and virsh command ``domdirtyrate-calc`` are added to start calculating a live domain's memory dirty rate. * qemu: Support reporting memory dirty rate stats The memory dirty rate stats can be obtained through ``virsh domstats --dirtyrate`` via the virConnectGetAllDomainStats API. * qemu: Full disk backups via ``virDomainBackupBegin`` The qemu hypervisor driver now allows taking full disk backups via the ``virDomainBackupBegin`` API and the corresponding virsh wrapper. In future releases the feature will be extended to also support incremental backups (where only the difference since the last backup is copied) when qemu adds the required functionality. * Add support for audio backend specific settings With this release a new ``
