dmesg output of archlinux guest

I'm running fedora host with archlinux guest and trying to run another VM inside the archlinux guest. On the fedora host, cat /sys/module/kvm_amd/parameters/nested outputs 1. This error only happens when running qemu with -enable-kvm flag, without the flag it works fine (but slow as expected).
