When creating a virtual machine with incus, the VM creates fine but does not start. Examining the logs, shows a unknown audio driver `spice`. I have tried with fedora, debian and ubuntu images and the issue occurred with all of them. Installing the `qemu-audio-spice` package eliminates the problem. Other qemu packages are listed as recommends of the incus-agent subpackage and I believe that the qemu-audio-spice package should be added to the list of recommends of incus agent so that VM creation works out-of-the box. Reproducible: Always Steps to Reproduce: 1.Install incus, letting dnf manage dependencies `sudo dnf install incus` 2. Create a virtual machine `incus launch --vm images:debian/12 debian-vm` Actual Results: `Error: Failed instance creation: Failed to run: forklimits ....` Expected Results: No output signalling success, and VM should be running in background. Additional Information: Running the command `incus info --show-log debian-vm` produces the following ourput showing that the problem is with Name: debian-vm Description: Status: STOPPED Type: virtual-machine Architecture: x86_64 Created: 2026/02/02 15:36 GMT Last Used: 1970/01/01 01:00 BST Log: qemu-system-x86_64: Unknown audio driver `spice`
