Could be due to this: [Rocky 8.6 host, Rocky 9.0 guest? - #2 by jlehtone](https://forums.rockylinux.org/t/rocky-8-6-host-rocky-9-0-guest/6601/2)

Check if sse4\* is accessible in the cpu on your Rocky Linux 8.x install, so:

```auto
cat /proc/cpuinfo | grep -i sse4

```

if you get zero results, that means VirtualBox is not passing through the functionality that allows RHEL9 and Rocky9 to work.
