Re: [Xen-users] IMA DOMU Kernel with VTPM

[Karthick R <karthick.ramachandran@xxxxxxxxx>]

The VTPM patch is from https://lkml.org/lkml/2013/7/1/540, not the one specified in the previous mail. Sorry about that.

Hi,

I have custom compiled  the linux-konrad-xen (3.10.0+) with VTPM patch from (http://lists.xen.org/archives/html/xen-devel/2013-03/msg01923.html) as DomU kernel. It has the following configuration:

CONFIG_XEN=y

CONFIG_TCG_TPM=y

CONFIG_TCG_XEN=y

CONFIG_IMA=y

When I boot the above DomU kernel *WITHOUT* ima_tcb=1, DomU boots properly. 

However, when I enable IMA (through extras="ima_tcb=1" in domu.cfg), the booting hangs at 

[info] Using makefile-style concurrent boot in runlevel S. 

Could anyone point me in a direction where I can debug this?

I have vtpmmgr and domu-vtpm running in different VMS and each of them get messages from when DomU boots. This is confirmed by 

> Saved hash and key for vtpm <uuid>

in vtpmmgr and

> vtpmblk.c Info: Wrote 6992 bytes to NVM persistent storage

in domu-vtpm. 

I am using Xen 4.3.1-rc1. 

Any help will be really appreciated.

Thanks!
