is virtualkd being actively maintained?

[Anonymous]

It seems like there are some bugs and virtualkd hasn’t rev’ed for a while. Is this project still going?

Actively – no. But if you have a bug, that is consistently reproducing itself, please write a detailed description and I will fix it.

[Some versions of] RtlAssert are not trapping into the debugger. It sounds like it’s a known problem: http://www.osronline.com/showThread.CFM?link=202105

I ran into this on Server `08 R2, x64. Here’s what I see when poking around and it seems consistent with Scott’s reply. The byte read has a value of 1 but is expected to be 3 – so it skips over the prompt to break into the debugger.

This is a pretty fantastic tool and I would be willing to contribute to it’s advancement. You can contact me privately if you like.
