kvm-intel does not load when Intel TXT is enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

when I enable Intel TXT (Trusted Execution Technology) in the BIOS settings of my Lenovo W510, the kvm-intel module does not load and says 'kvm: disabled by bios', despite the fact that both VT-x and VT-d are enabled. Disabling TXT enables hardware virtualization and kvm-intel works as expected.

Are VT-[xd] and TXT supposed to be mutually exclusive? Or could it be a BIOS bug?
