QEMU 8.0 is out today as the newest feature release for this processor emulator that plays an important role in the open-source Linux virtualization stack.

QEMU 8.0 has debuted as stable today with a range of new features and other improvements. Some of the highlights for QEMU 8.0 include:

- QEMU 8.0 now supports Xen guests under KVM when running on the Linux 5.12 kernel or newer.

- System emulation on 32-bit x86 hosts has been deprecated. The 32-bit x86 host support for system emulation is deemed no longer effective.

- Due to Intel HAXM being retired, the "-accel hax" option has been deprecated.

- New ARM emulated CPU types of Cortex-A55 and Cortex-R52.

- QEMU 8.0 on RISC-V supports a number of new extensions like smstateen, Zawrs, the T-Head vendor extensions, Svadu, Zicond, and Zicbiom, ZCicboz, and Zicbop. QEMU 8.0 is also now capable of supporting ACPI on RISC-V.

- QEMU 8.0 adds a new CPU model for Intel Sapphire Rapids.

- A new "ide-cf" option for emulating a CompactFlash card block device.

- Support for the F13 and F14 keys have been added for input handling.
