Hi Peter
Thanks you so much.
I tried to specify corresponding initramfs to QEMU as following
qemu-system-x86_64 \
-kernel /boot/vmlinuz-`uname -r` \
-m 4G \
-initrd /boot/initramfs-`uname -r`.img \
-sda centos79.img \
-append "root=/dev/sda console=ttyS0" \
-enable-kvm -nographic
It worked for me to boot the kernel.
However, I still can’t enter the system.
Qemu reported following information
[ OK ] Reached target System Initialization.
Starting dracut initqueue hook...
Starting Show Plymouth Boot Screen...
[ OK ] Started Show Plymouth Boot Screen.
[ OK ] Reached target Paths.
[ OK ] Reached target Basic System.

I can't find the sda or hda in the /dev directory inside qemu.
What should I do to fix this problem?
Sincerely!
