The latest release for the emulator offers support to log in to the guest events through the ACPI ERST interface. QEMU 7.0 brings improved security label support for the virtiofs for virtual machines. Additionally, the support for non-qcow2 images and Intel AMX on the x86 platform has been added in this release.
The following release contains 2500+ commits from 225 authors.
The QEMU 7.0.0 release contains the highlighted features listed below:
- ACPI: support for logging guest events via ACPI ERST interface
- virtiofs: improved security label support
- block: improved flexibility for fleecing backups, including support for non-qcow2 images
