Do you use the CPU type host, max or any other type that has aes already included?

If you use kvm64 for example, then you need to enable it in Advanced, Extra CPU Flags. Whether this actually works also depends on pfSense. If it detects a very old CPU type (like 486) then it might not bother to check the aes flag.

Hope this helps and best regards
