The red part of XEN to start early in the blue part of the Linux operating system startup, I want to know about the, XEN is start after another and the Linux operating system run in parallel in the physical machine's operating system? Or and then start the Linux merge into an operating system?
In addition, used here Grub2 instructions, such as multiboot2, module2, respectively is what mean?
Thank you very much!
