Michael,
Look at this post to see how you can check if VT-x is enabled

Hi Michael,
TXT/VT-x/VT-d need to be enabled, can you check your machine to make sure
they are enabled?
Regards,
Sun Ning

Subject: [tboot-devel] Tboot Installation Issues
Hello,
I am trying to install tboot on 2 systems - one running RHEL 6.5 and one
running Ubuntu. I did the following steps, to no success:
#tpm_takeownership -z
# yum install trousers-devel tpm-tools tboot
modify /boot/grub/grub.conf so that the first line looks like this:
title tboot Red Hat Enterprise Linux Server (...)
root (hd0,0)
kernel /tboot.gz loglvl=all logging=serial,vga,memory vga_delay=1
module /vmlinuz ... (kernel)
module /initramfs ... (initrd)
(Both systems are equipped with SINIT in the BIOS, so there was no need to
add it as a module in the configuration above.)
I did equivalent steps on the Ubuntu machine.
Neither machine showed any signs of having successfully run tboot:
- txt-stat shows that 'TXT measured launch' is FALSE
- TPMs are owned, enabled, and active
- pcr values are as follows:
PCR-00 to PCR-07 contain values as expected
...
PCR-08: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
PCR-09: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
PCR-10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
PCR-11: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

PCR-15: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
PCR-16: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
PCR-17: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
PCR-18: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
PCR-19: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
PCR-20: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
PCR-21: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
PCR-22: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
PCR-23: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
The following errors were given by txt-stat as well:
...
TBOOT: TPM: fail to get public data of 0x20000001 in TPM NV
TBOOT: :reading failed
...
TBOOT: TPM: fail to get public data of 0x40000001 in TPM NV
TBOOT: :reading failed
TBOOT: failed to read policy from TPM NV, using default
TBOOT: policy:
...
TBOOT: Error: write TPM error: 0x2.
TBOOT: no policy in TPM NV.
TBOOT: IA32_FEATURE_CONTROL_MSR: 00000007
TBOOT: CPU is SMX-capable
TBOOT: ERR: SENTER disabled by feature control MSThR (7)
TBOOT: SMX not supported.
TBOOT: no LCP module found
TBOOT: Error: ELF magic number is not matched.
...
Both machines have similar output for txt-stat with the exception that the
'ERR: SENTER disabled by feature control...' error only showed up on the
RHEL machine.
One interesting thing that I noticed that might be connected to the problem
is that the 'tpm_tis.ko' module does not exist on either machine.
Does anyone have an idea of why tboot is not successfully activating the
DRTMs and what I could do to solve the problem?
Thanks,
Michael
