@ -38,10 +38,31 @@ v10.10.0 (unreleased)
Updates to QEMU CPU models with -vN suffix can now be used in libvirt just
like any other CPU model.
* qemu: Support for the 'data-file' QCOW2 image feature
The QEMU hypervisor driver now supports QCOW2 images with 'data-file'
feature present (both when probing form the image itself and when specified
explicitly via ``<dataStore>`` element). This can be useful when it's
required to keep data "raw" on disk, but the use case requires features
of the QCOW2 format such as incremental backups.
* **Improvements**
* qemu: Support UEFI NVRAM images on block storage
Libvirt now allows users to use block storage as backend for UEFI NVRAM
images and allows them to be in format different than the template. When
qcow2 is used as the format, the images are now also auto-populated from the
template.
* **Bug fixes**
* qemu: Fix reversion and inactive deletion of internal snapshots with UEFI NVRAM
In `v10.9.0 (2024-11-01)`_ creation of internal snapshots of VMs with UEFI
firmware was allowed, but certain operations such as reversion or inactive
deletion didn't work properly as they didn't consider the NVRAM qcow2 file.
