Though I use Ubuntu, I installed KVM from source code. And the vanilla
QEMU is not installed. And I use the KVM binary for QEMU (so no
accelerator is active in that case)

And there is no /usr/bin/qemu, but only /usr/bin/qemu-system-x86_64 in
KVM installation.

There is nothing like qemu-kvm anywhere in my box. I guess that is
from Fedora package only? (I compiled and installed KVM from source
code)
