We have taken a look at this year's GSoC project list ( https://wiki.xenproject.org/wiki/Outreach_Program_Projects). We were interested in learning more about the "KDD (Windows Debugger Stub) enhancements" project and Xen on ARM based projects. Yet, on irc we were told that this list is outdated. If there are any other project suggestions or list, we would be interesting in learning more about them. Andrew Cooper suggested on irc the following project: Context Switching with CR0.TS in HVM Guest. We would like to possible know more about this project in terms of difficulty, potential estimate on time required. Andrew also mentioned a slighter bigger xen/linux project and we would like to know more detail about this one as well.

However, debugging a Windows guest with emulated serial is very slow and clunky so a solution like KDD is very desirable. The goal of a project would be to get the code functional against a recent version of Windows (i.e. 10) such that we could run windbg against it and walk kernel data structures, set breakpoints etc. without having to enable debugging within the guest.

The kd protocol is a packet protocol and windbg is essentially in control; issuing commands to dump registers, memory etc. Setting normal breakpoints would indeed mean modifying guest memory and then dealing with the ensuing int3s. You may also get requests from windbg to use debug registers. I *think* the main issue with post-Windows 7 is going to be KASLR, but there may be a way to ask Windows to turn it off for debugging purposes without actually turning on full debug mode… I don’t know. Even if Windows does need to be put in debug mode, using kdd would be preferable to setting up emulated serial.
