Comment # 3 on bug 1217342 from Christian Eggers

Same problem on current openSUSE-15.6 beta (with stock kernel)!

I just installed the latest beta of openSUSE-15.6. Here kernel 6.4 is shipped.
I also had to manually add the openSUSE signing key with mokutil.

After that I started VirtualBox and created a new machine (with default
settings). Again the machines startup freezes at 20% and it is not possible to
terminate the VM / close the VirtualBox window.

This should definitely be fixed until openSUSE-15.6 GA.
