Hi, I am a student currently working on development of a Hypervisor for JOS Operating System.
I run JOS over QEMU's emulation of x86 architecture. Currently I am planning to add Nested Page Table support to JOS. Does QEMU emulate the Nested Page Tables implemented by AMD-V architecture or the Intel VT? Also I am trying to understand the QEMU source with an objective of participating in the Google Summer of Code and contributing to QEMU. I have tried tracing through the code but seems this link http://repo.or.cz/w/qemu/stefanha.git/blob_plain/refs/heads/tracing:/docs/tracing.txt is not updated because many of the options do not work here. I would very happy if someone could provide me links to a good starting point to understand QEMU source code. Thanks, Ankur
