Thanks for your advice. I will try the tools.
I also found the article about how to create and mount image.
https://midnightprogrammer.net/post/create-mount-and-unmount-img-files-in-ubuntu/
The article says, the image file created by dd should formated in ubuntu.
For Centos, should I format the image file before mounting it as virtual read-only disk?
Thanks!
