Vmware vGPU add / VVTD

Virtual GPU Forums General Discussion

Hi
I have problems on adding a vgpu on a vmware vm. The vm had enabled VBS (Virtual Based Security). I have disabled it, but anyway I get the message, that VVTD (Intel Virtualization Technology for Directed I/0) is not supported.
On a fresh clean vm I can add the vpu.
How could I disable that VVTD on that vm?

Cheers
Lukas

Solved:

shutdown vm
disable VBS
delete following lines in vmx-file:

vvtd.enable = "TRUE"
vhv.enable = "TRUE"

Thanks, I disabled Intel VT-D in BIOS but still got this message. So I searched the setting in the VM settings via the vSphere Client but found nothing. The vmx file can be found using “find /vmfs/volumes/ | grep vmx$” on the vSphere server command line.

Update: Do not disable VT-D in BIOS! Just remove the lines or set vvtd.enable to “FALSE” in the vmx file. VT-D is actually needed by the vGPUs.
