This is intended.

Unfortunately, there's no way to build a binary that supports both kvm and kqemu.
There are ongoing upstream threads about it. kqemu is dead technology, not because of its functionalities, but because it imposes *severe* limitation on upstream qemu, and currently no one have the will or skill to maintain it.

In fedora, we don't ship the kernel module, because it is not in upstream kernel. So if you want to run kqemu, you'll need to build the module anyway. Just build your own qemu in that case.
