guest serial output

Description of problem:
I tried to install RHEL-8.3.0 kvm guest using cdrom on aarch64. There are 3 modules "floppy", "edd" and "iscsi_ibft" failed to load at the installation stage. "iscsi_ibft" module can be tracked by bug 1790898.
This does not affect the guest installation, I can successfully install it.
In addition, these 3 modules cannot be found in ppc64le, but the installer will not have this problem. So I guess these modules should not try to load on aarch64.

Version-Release number of selected component (if applicable):
RHEL-8.3.0-20200909.1
kernel-4.18.0-235.el8.aarch64

I am not sure if the component I selected is right, please help to correct it if I am wrong.
