A new version of the open cross-platform emulator for various processor architectures, QEMU, has been released.
The most interesting changes are:
- A virtio-sound device has been added, allowing audio to be captured and played back on a suitably configured host backend.
- A virtio-gpu rutabaga device has been added, offering various GPU abstractions and screen virtualization.
- It is now possible to migrate VMs with virtio-gpu blob=true, and the new parameter 'avail-switchover-bandwidth' will assist users who experience prolonged and less controllable migrations.
- A memory leak in guest-exec has been fixed.
In total, changes have affected 14 architectures, primarily RISC-V and ARM.
Other changes include:
- The QEMU-KVM binding requires kernel 4.4 or higher (future plans may increase the requirement to 4.19);
- machine types from pc-i440fx to pc-i440fx-1.7 are no longer supported.
