Hi Rudolfs, 

For Windows, yes, hardening was implemented in 4.3.14. For other host platforms, hardening was introduced so long ago that I couldn't tell you when exactly. Long before 4.3 for sure.

Hi Klaus, 

thanks for the response, I guess I'll move up to 4.3.26 then and start debugging. Just a quick question - maybe I misread but I understood that hardening was introduced in 4.3.14? 

Best Regards, 
Rudolfs Bundulis

Yes - the logs start to differ where VBoxHeadless started setting up the 
VM. The same didn't happen in your frontend (because it failed before 
getting to this point). This could be an issue with hardening, but it's 
hard to tell what exactly is the cause. 

Finding out where the failure originates in VMR3Create (it does a lot!) 
is hard work but probably unavoidable. Have fun with gdb or whichever 
debugger does the trick for you.
