[vbox-dev] VM-debugger status

[Ramshankar]

The VM debugger should work in principle but there may be bugs that may 
be specific to CPU hardware features.

The ticket you pointed to for instance, 
(https://www.virtualbox.org/ticket/17348) does not provide sufficient info.

The best way to get a problem solved is by giving us a VBox.log and the 
simplest, smallest reproducible test-case on how to trigger the issue.

Here is what I usually use: "ba x 1 <cs:rip-address>"  That sets a 
breakpoint at the cs:rip you need to break at. Once the breakpoint 
triggers, you can single step using "t" (trace) or continue 
guest-execution using "g" (go).


Regards,

Ramshankar.
