It's probably something specific to your distro, then. Try selecting a specific CPU type matching your actual CPU generation, or use a different Linux distribution.

Try rebooting the host machine.
This seems weird but it is just happened to me. I am using debian stretch and While installing a gust OS(some distribution of ubuntu) on KVM for the first time after installation, I got the same alert. I shutdown the host machine leaving the issue unresolved and the next day while trying again, I got no error at all. Meanwhile I did absolutely nothing. There is a possibility that KVM needs a restart for complete installation or to collect necessary data. Though I am not sure about arch but you can give it a try before proceeding for another solution.
