vtpm_manager can''t run twice in a row
I can get vtpm_manager to run if I delete /var/vtpm/VTPM. However, when
I kill it with control-c, and try to run it again, I get:

Using TPM in dom0
Hi,
i am using Xen 3.2.0 and want to use the TPM in dom0. I have activated vtpm and everything runs fine in my domUs.
The question is, how can I access the TPM in dom0? As far as I know vtpm_managerd exclusively locks /dev/tpm0. As soon as I start vtpm_managerd my own program cannot access the TPM anymore. Is there a vtpm instance for dom0 like the ones for the user domains?
Thanks in advance for any hints,
Tom

[TPM, vTPM] Persistence of data on VM?
...on my VM''s, my wish is to make some sealing tests on my VM''s/
So here are all the operations I do :
*On the Dom0*
/etc/inid.d/trousers stop # TrouSerS prevents use of the vtpm manager,
becauser the vtpmm cant use the TPM is another application is already using
it
xend start

*On the DomU
*modprobe tpm_xenu
