Hi, Guan
Could you enable vTPM now? My vTPM is always print out below error when
I enable vtpm-stubdom.
ERROR[VTPM]: LoadKey failure: Unrecognized uuid!

Could you share some experience? Thanks in advance.

Do you use the new version of vTPM, which uses the vtpm-stubdom？ I failed to make it work in my computer before. Moreover, it doesn''t support the VM migration now. So, I just port the old version vTPM (got it from the Xen-3.4.2/tools/) to the Xen-4.3-unstable. It doesn''t use the vtpm-stubdom. 2013/6/26 Xu, Quan <quan.xu@intel.com>> Hi, Guan**** > > Could you enable vTPM now?

Yes, I try to enable vTPM in Xen-4.3-unstable. There are some difference between
xen 4.3 and previous version. in Xen 4.3 we’ll be moving to a “stubdomain-only”
model, unifying the vtpm system and making it much more secure.
How to deal with migration is an interesting and necessary topic for vTPM. BTW
my team will try to enable below 3 topics:
1. enable xen vTPM to allow programs to interact with a TPM in a virtual
machine, the same way they interact with a TPM on the physical system.
2. intergrate xen vTPM in openstack cloud. virtual machine in OpenStack can work
with Xen vTPM.
3. promote TPM 2.0 in Xen. Xen vTPM can run on TPM 2.0.
What about trying to enable vTPM together first.
In Xen release note wiki (http://wiki.xen.org/wiki/Xen_4.3_Release_Notes), it
noted ‘qemu-upstream is now the default for VMs not using stub domains. You can
change this by adding device_model_version = "qemu-xen-traditional" to
your config file.’
Maybe it is a good approach to make it work. I will try it this afternoon.
BTW:
XSM should enable first.
Thanks

based on the TPM emulator. As the Xen guys advised before, it seems that it will

Pat Pat, as Xen-4.3-unstable/docs/misc/vtpm.txt, you must have an machine with
a TPM on the motherboard.
…..
Prerequisites:
--------------
You must have an x86 machine with a TPM on the motherboard.
…..
Emulate TPM does NOT work for Xen-4.3-unstable vTPM.
In Xen release note wiki (http://wiki.xen.org/wiki/Xen_4.3_Release_Notes), it
noted ‘qemu-upstream is now the default for VMs not using stub domains. You can

I use the PV guest and maybe this option device_model_version doesn't work.
