REST Api understanding and hacking: https://api.github.com/

REST API hacking? https://docs.github.com/en/rest/reference/git

First go to: https://api.github.com/users/tthtlc/followers

And I can get a snapshot all my followers and details. WOW…

Then how about another developer’s followers:

https://api.github.com/users/vlordier/followers

And generically what are all the API that github.com provides?

Pointing your browser to https://api.github.com/:

Or shown as text below:

Nested Virtualization and How it Work?

Complete setup procedures:

https://stafwag.github.io/blog/blog/2018/06/04/nested-virtualization-in-kvm/

And its internals explained here:

https://hhb584520.github.io/kvm_blog/files/virt_others/NestedVirtualization.pdf

VMCS original design and flow

VMCS recent changes

L0, L1 and L2 are explained inside:

https://www.kernel.org/doc/Documentation/virtual/kvm/nested-vmx.txt

Single-level virtualization has two levels – the host (KVM) and the guests.
In nested virtualization, we have three levels: The host (KVM), which we call
L0, the guest hypervisor, which we call L1, and its nested guest, which we
call L2.

And for VMCS you also have VMCS12:

and others like VMCS01, VMCS02 etc.

To cater for the page table of the guest, we have “Extended Page Table”:
