Description Alexander Todorov 2013-09-09 13:16:17 UTC
Description of problem:

On a KVM guest:

In a default install select tboot package from the optional packages list (Base->Base->Optional->tboot). Complete the install. 

tboot is installed, 
grub.conf is configured to use tboot

system fails to boot, can't find rootfs volume. 


According to our test case this is a bug!

I'm not sure I really understand your test case--why are you trying to install tboot on a machine without a TPM module?

We install @everything and then upgrade. It so happens that tboot goes into the transaction as well. 

I don't understand why tboot always tries to be the default kernel and why it simply doesn't skip over to Linux when there's no TPS module present.

RHEL6.6 is using tboot v1.8.2.

Does this problem persist in RHEL6.6?

Comment 8 Alexander Todorov 2015-10-06 10:59:19 UTC
tboot-1.8.1-1 is in RHEL 6.7. Following the instructions from comment #0 the result is: system was able to boot. Closing.
