Hello together,
Intel VT is activated in BIOS,
Core i 7 950,
Hyper-V feature has been deactivated,
I am not running Windows in a VM,
soo why does it say VT would not be activated in BIOS if it is?
What other things can i try and steps can i take??

Thank you.

Thx for replying.
core virtualization protection? Where to find?
Is it the Windows Security - Core Isolation - Memory Integrity?

This one is off:

check again that Intel-VT (not vt-D) is enabled in your bios.
make sure you read the text properly. e.g some bioses have it as "disable intel vt" : enabled/disabled. In that case it has to be disabled

execute this lua code and check what it prints out
Code:

if (cpuid(1).ECX & (1 << 5))~=0 then
  print("Your system supports DBVM")
else
  print(string.format("Your system does not support DBVM : %8x",cpuid(1).ECX ))
end

Yes, your system must support virtualization for DBVM to work (DBVM is a virtual machine)

ultimap: intel branch tracing and dbvm for recording only when on the correct CR3
ultimap2: intel process trace, and dbvm if you wish to use ranges+interrupts (to hide it from windows, as they want a monopoly on that feature. It can work without dbvm if you don't use ranges)

It's never going to work on AMD even if dbvm is supported

ok so for ultimap it would be 21st bit of EDX when CPUID use EAX=1h to confirm Intel Branch Tracing?
and for UM2 it would be 25th bit of EBX while EAX was 7h? right?
