Cannot boot and set rhel7 or 8 s390x on Redhat 8(Host OS) using qemu-system-s390x

Hi, Hello, I tried to boot rhel 7or 8 (s390x) on Redhat 8 as Host OS using qemu-system-s390x I failed to complete the boot setup. Every time there is an error as below:

[FAILED] Failed to start Load Kernel Modules. See 'systemctl status systemd-modules-load.service' for details.

---

Ends with

Starting Setup Virtual Console... [ OK ] Started Setup Virtual Console. Starting Dracut Emergency Shell... Warning: /dev/root does not exist Generating "/run/initramfs/rdsosreport.txt"

Entering emergency mode. Exit the shell to continue. Type "journalctl" to view system logs. You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot after mounting them and attach it to a bug report.
