I am happy to report that upgrading the UEFI to v1.60 resolved the issue.]]> Sun, 15 Oct 2017 02:51:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=6330&PID=38002&title=x299-taichi-and-intel-virtualization-vtx#38002 <![CDATA[x299 Taichi and Intel Virtualization (VT-x) : No, this is on a clean installation...]]> https://forum.asrock.com/forum_posts.asp?TID=6330&PID=37976&title=x299-taichi-and-intel-virtualization-vtx#37976 Author: iconoclast

No, this is on a clean installation of Windows. I am not even allowed to install the Hyper-V feature (the only hypervisor I'm planning on running) because of this.]]> Sat, 14 Oct 2017 11:19:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=6330&PID=37976&title=x299-taichi-and-intel-virtualization-vtx#37976 <![CDATA[x299 Taichi and Intel Virtualization (VT-x) : Is this with another Hypervisor...]]> https://forum.asrock.com/forum_posts.asp?TID=6330&PID=37969&title=x299-taichi-and-intel-virtualization-vtx#37969 Author: wardog

Is this with another Hypervisor installed that you see this?

If you have VMware or the like installed, disable MS's Hyper-V. Only one hypervisor is allowed.

How do I disable Hyper V?
  1. Hit the Windows Key and type "windows features"
  2. Hit the Windows Key + W combo to bring up the Windows Settings panel of the Start Screen.
  3. Click on Turn Windows features on or off.
  4. When the Turn Windows features on or off dialog appears, look for Hyper-V and deselect it.
  5. Click OK.
  6. Restart your computer when prompted.

I just bought an x299 Taichi board and fitted it with an i9 7940x, which according to the datasheet supports both VT-x and VT-d.

"Intel Virtualization Technology" and "VT-d" are both enabled in the UEFI, I use 64-bit Windows 10 Pro but systeminfo.exe reports the following under "Hyper-V Requirements":
- VM Monitor Mode Extensions: Yes
- Virtualization Enabled in Firmware: No
- Second Level Address Translation: Yes
- Data Execution Prevention Enabled: Yes

Fast Boot is disabled (I've read that enabling that can mess with virtualization).

I am using UEFI v1.40. I see there's a newer version (v1.60), but want to make sure there's absolutely nothing else I can do before that.
