11302,Hardware Breakpoints not tirggered without vt-x,hwbpfan,,"hello,

hardware Breakpoints are a basic cpu feature of the x86 and x64 architectures. In virtualbox, this feature does not work if vt-x is disabled or not present, even though HWBPs have nothing to do with vt-x.

the problem has been previously mentioned and partly resolved here:

virtualbox.org/ticket/477

but is still present in latest version 424. The expected interrupts are just swallowed by the VMM.


To reproduce this issue, disable vt-x for a specific machine and use your favourite debugger to set a hardware breakpoint.
I suggest you try windows+ollydbg (ollydbg.de), as it`s very easy to use.

Didnt attach any logs as it?s very easy to reproduce on any machine and there`s nothing interesting in the logs.",defect,closed,VMM,VirtualBox 4.2.4,duplicate,"hwbp, hardware breakpoint",,all,all
