[Xense-devel] vtpm_managerd problem

[Burak OÐUZ <burakoguzs@xxxxxxxxx>]

Hi,

I am a newbie in tpm virtualization on Xen. I have a working IFX Tpm. I have a few questions about the usage of the vtpm_managerd and vtpm usage :
 
1 - vtpm_managerd gives that error

dungeon trousers-CVS # vtpm_managerd
INFO[VTPM]: Starting VTPM.
INFO[TCS]: Constructing new TCS:
ERROR[TXDATA]: TPM open failedERROR in VTPM_Init_Manager at vtpm_manager.c:205 code: TPM_IOERROR.
ERROR[VTPM]: Closing vtpmd due to error during startup.

2 - How can I activate vtpm on domUs? After modprobing the tpm_xenu  I start trousers on a domU, it gives such an error :

pardus ~ # tcsd -f
TCSD tcsd_conf.c:644 resetting mode of /usr/local/var/lib/tpm to: 01777
TDDL tddl.c:116 WARNING: ioctl: (25) Inappropriate ioctl for device
TDDL tddl.c:117 Falling back to Read/Write device support.
TCS tcs_utils.c:262 ERROR: TCS GetCapability failed with result = 0x9

3 - Also if you have any resources other than IBM documents and  Xen User Manual  that will be very useful...

Thanks in advance..

Best regards
