QEMU 9.0 is out tonight as the latest feature release for this prominent component to the open-source Linux virtualization stack.

There are many changes to be found with today's QEMU 9.0 processor emulator release. Some of the QEMU 9.0 highlights include:

- LoongArch KVM accelerated support is added as well as handling LSX/LASX AVX-like extensions.

- RISC-V sees support for the Zacas extension, RVA22 profiles, and other new RISC-V extensions.

- The virtio-blk block driver has gained "true" multi-queue support so that different queues to a single disk can be processed by different I/O threads. This true multi-queue I/O for virtio-blk allows for better scalability.

- QEMU's crypto subsystem now allows using the SM4 cipher and can be used with the LUKS block driver.

- QEMU on KVM now requires the Linux 4.4+ kernel with older kernel versions no longer being supported.
