First, I will clean TPM ownership by BIOS. If the /var/vtpmmgr-stubdom.img is created by below cmd, dd if=/dev/zero of=/var/vtpmmgr-stubdom.img bs=16M count=1 it will always print out: ~~~ ERROR[VTPM]: Invalid ID string in disk image! ERROR[VTPM]: Failed to load manager data! ~~~ So I use tty linux image instead. Also I will change UUID of tty linux image by below cmd: uuidgen | xargs -i tune2fs /var/vtpmmgr-stubdom.img -U {} now there is another error (ERROR[TPM]: Failed with return code TPM_NOSRK). I will continue focus on fixing it. I think I should create SRK manually by tools. do you have some suggestion?

* Re: [Xen-users] some problems to start vTPM vtpm-stubdom 2013-07-08 22:32 ` Daniel De Graaf @ 2013-08-02 9:34 ` Xu, Quan 0 siblings, 0 replies; 3+ messages in thread From: Xu, Quan @ 2013-08-02 9:34 UTC (permalink / raw) To: Daniel De Graaf; +Cc: Ian Campbell, xen-devel@lists.xen.org Hi, Graaf Thanks for your/Ian's help. Now I can run vTPM. I will show a demo to mgr/ colleagues, then I can get more resource for below topic: 1. enable vtpm. (DONE) 2. intergrate xen vTPM in openstack cloud. virtual machine can interact with a TPM on the physical system. (status: starting on this topic). 3. fix the 3 bugs. Also you can check it first. Bug 1, as you said, enabling XSM seems to be a workaround, but there is no description in doc. We should fix it: (status: start it in next week, August 5th) (1) bug1: if the Xen SXM is not enabled, the vtpmmgr failed to read/write Address: FED40000. ddress: FED40000 Enabled Localities: 0 Map 1 (fed40, ...) at 0x----------- failed -1. (2) it will print out bellow error message at vtpmmgr first boot. After debug, I know the ID is zero string, not "VTPMMGRDOM". It will confuse new developers/users. ERROR[VTPM]: Invalid ID string in disk image! ERROR[VTPM]: Failed to load manager data! (3) it will print out bellow error message at vtpm first boot, After debug, there is no HashKey in vtpmmgr at all. The hash key is saved to vtmmgr when the virtual Machine start with ' vtpm=["backend=domu-vtpm2"] ' configuration. Error: VTPM_LoadHashKey() failed with error code .... ERROR[VTPM]: LoadKey failure: Unrecognized uuid! 69743ae0-9d4a-4ad6-9819-e602085b6792 4. support HVM domu. Currently only paravirtualized guests are supported. Does anyone start to do it? If not I can drive it. I know the data center VM Is most in HVM model. As my opinion, it high priority to start it. also it is challenge. (status: start it in next week, August 5th) 5.Integrate with OpenAttestation. (status: starting on this topic). OpenAttestation project is to provide SDK, Software Development Kit, to add cloud management tools with capability of establishing hosts integrity information by remotely retrieving and verifying Hosts' integrity with TPM quote. The github: https://github.com/OpenAttestation/OpenAttestation 6. Promote TPM 2.0 in Xen. Xen vTPM can run on TPM 2.0. (hold on, we can fix some bug and enhance TPM 1.2 first) Quan Xu Intel > -----Original Message----- > From: Daniel De Graaf [mailto:dgdegra@tycho.nsa.gov] > Sent: Tuesday, July 09, 2013 6:32 AM > To: Xu, Quan > Cc: Ian Campbell; xen-users@lists.xen.org; xen-devel@lists.xen.org > Subject: Re: [Xen-users] some problems to start vTPM vtpm-stubdom > > On 07/05/2013 05:10 AM, Xu, Quan wrote: > > > > > >> -----Original Message----- > >> From: Daniel De Graaf [mailto:dgdegra@tycho.nsa.gov] > >> Sent: Tuesday, July 02, 2013 5:39 AM > >> To: Xu, Quan > >> Cc: Ian Campbell; xen-users@lists.xen.org > >> Subject: Re: [Xen-users] some problems to start vTPM vtpm-stubdom > >> > >> On 06/25/2013 07:52 AM, Xu, Quan wrote: > >>>> From: Ian Campbell [mailto:Ian.Campbell@citrix.com] > >>>> Sent: Tuesday, June 25, 2013 5:16 PM > >>>> To: Xu, Quan > >>>> Cc: xen-users@lists.xen.org; Daniel De Graaf > >>>> Subject: Re: [Xen-users] some problems to start vTPM vtpm-stubdom > >>>> > >>>> On Thu, 2013-06-20 at 03:18 +0000, Xu, Quan wrote: > >>>>> Hi community, > >>>>> there are some problems to start vTPM vtpm-stubdom following > >>>>> docs/misc/vtpm.txt. > >>>> > >>>> You might have better luck getting help with your problems if you > >>>> CC the vTPM maintainer as listed in the MAINTAINERS file in the > >>>> source tree.
