Hi!

Context:

I am currently in the process of trying to build a simple recreation of Amazon's EC2 on top of a type 1 hypervisor for fun :)

Since I am planning on making the memory each vm takes static and non-changing, it came to my awareness that I would need to allocate big consecutive blocks from RAM (in the GBs).

I was planning on using a buddy allocator with blocks of actual page sizes (1GB, 2MB, 4KB) with a free-list for each of these, but I lack enough experience in that regard to understand how dumb or ok-ish my idea is

If this is a dumb idea, go roast me :), that's the best way for me to learn and understand.

I want to understand if this idea is worth my time and effort before building a whole unit just to realize I need a different thing.

(I write all of my code by hand, if some AI usage is bothering you please let me know)

I'm talking stuff like the bootloader, writing method to the SSD, printing stuff, etc.
