With the update to qemu 7.0.0 the package has been turned into a more fine grained split package utilizing meta packages.

* The `qemu` package is now virtually provided by the meta packages `qemu-base`, `qemu-desktop` and `qemu-full`. * The functionality of `qemu` prior to 7.0.0 is replaced by `qemu-desktop` * The functionality of `qemu-headless` is replaced by `qemu-base` * The functionality of `qemu-arch-extra` and `qemu-headless-arch-extra` is replaced by `qemu-emulators-full` * The meta package `qemu-full` provides all QEMU related packages (excluding `qemu-guest-agent`)
