You would likely have to try experiment with qemu cmdline or use latest qemu and check the qemu mailing list

Hi,
As the next email in the thread mentions, worth trying different CPU family (make sure you dont’ use anything too old due like Conroe), or host CPU passthrough.
I would certainly suggest to try the qemu-kvm-rhev/ev since it focuses on stability. Try RHEL/CentOS host instead of Fedora. 

Thanks,
