Xen users - Feb 2006 - VTPM problem with Xen 3.0 when starting vtpm_managerd

Hi there,



I tried to get the VTPM running in my Xen 3.0 installation, but it
doesn''t
seem to work so far.



My system:

- xen-unstable 3.0 build from source, downloaded in Jan 06

- Fedora Core 3 on host and guests

- bridge-utils 1.0.6

- gmp-4.1.4



I don''t have a TPM chip onboard, so I use the TPM emulator that is
delivered
in the source of xen-unstable. The patches are all applied and the emulator
seems to be alright, a device is installed as /dev/tpm0.



Now I launch the vtpm_managerd and it initializes fine until it then says:



"ERROR[VTPM]: [1] Can''t open inbound fh for /dev/tpm0."





I found a similar thread on
http://lists.xensource.com/archives/html/xen-users/2005-09/msg00796.html but
no answer.



When I start my guest domain the xend log files don''t show any errors
and
say that "The domain has a TPM with instance 2 and devid 0."



Can anybody help me to get the VTPM working?



Thanks,

Anna
