Indeed .. I just hit this with my own guest.  For reference, the error was:

error: Failed to start domain f19rawhidex64
error: internal error Child process (LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin /usr/bin/qemu-kvm -help) unexpected exit status 127: /usr/bin/qemu-kvm: line 3: /usr/bin/qemu-system-x86: No such file or directory

and the fix was to 'virsh edit' the guest and remove the <emulator>
element.
