Cannot IPL this ISO image

Hi, please help me.

When I try to install rhel7.9(s390x) on Rhel8.5 as host os. I counter the error message:

LOADPRAM=[ ] Using virtio-scsi. SCSI CD-ROM detected

! Cannot IPL this ISO image !

Is this error due to difference between version of Guest and HOST OS or other?

How can we install rhel7.9 zlinux on rhel or centos host os?

Thanks in advance,
