Hi, In the IMA enabled guest OS [1] of my Xen setup, IMA is failing to create bios_measurements file (/sys/kernel/security/tpm0). It has the following data: [ 65.227006] read_log: ERROR - Could not get TCPA table cat: binary_bios_measurements: Input/output error Is this because of the virtual bios of Xen? I tried changing the BIOS to rombios or seabios, it resulted in the same output as above. Querying the BIOS using dmidecode also fails with the following error. # dmidecode 2.9 # No SMBIOS nor DMI entry point found, sorry. Is this the expected behaviour of guest os within Xen? Any help will be greatly appreciated. [1] I have custom a compiled the linux-konrad-xen (3.10.0+) with VTPM patch from ( https://lkml.org/lkml/2013/7/1/540) as DomU kernel. It is installed over Ubuntu Quantal. Dom0 runs Debian Wheezy.
