VT-x and TPM (MVMM) support
Posted: 27. Jun 2009, 19:47
Hello,
I have just figured out why on my Dell Latitude E6400) when enabling in BIOS all VT-x support, VirtualBox (2.2.4 and 3.0.0 Beta2) always report VT-x feature disabled:
00:00:01.756 HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_VMX_MSR_LOCKED_OR_DISABLED
00:00:01.757 HWACCM: VMX MSR_IA32_FEATURE_CONTROL=ff0b
This is because I have enabled in BIOS the third VT-x option to virtualize TPM support.
When I disable VT-x TPM support then VirtualBox (2.2.4 and 3.0.0 Beta2) is then capable to use VT-x:
Wouldn't it be better if in the log VT-x TPM is detected and a more meaningful warning is generated to guide the users to resolve more easily this issue?
thanks,
andrea
