[Xen-users] vTPM not working in domU

[Sebastian Biedermann <biedermann@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi list,

IÂm not able to use a vTPM in a domU and I cannot figure out what is 
going wrong.
IÂm using Xen 4.0.1 and prepared kernel dom0 package for debian squeeze.

In the dom0, the TPM is working fine.
So I added to the domU config file the line:

vtpm = [ 'instance=1 backend=0']

ID=1 for the domU instance and ID=0 for the domO instance with the 
working TPM.
But when I start domU there is following error:

Error: Device 0 (vtpm) could not be connected. Hotplug scripts not working.

I dont know whats wrong, the IDÂs of the domains are correct

The xend.log File says:

Anyone has an idea what I could try?

Thank you!
