Run this command. You will need to adjust the path to the kernel:

/usr/libexec/qemu-kvm -no-user-config -nodefaults -display none \
    -machine accel=kvm:tcg,graphics=off -cpu max,la57=off -m 1024 \
    -no-reboot -kernel /boot/vmlinuz-5.14.0-349.el9.x86_64 \
    -serial file:/dev/stdout \
    -append 'panic=1 console=ttyS0 printk.time=1'

It will hang at:

What's supposed to happen is the VM reboots (causing qemu to exit because of the -no-reboot option):
