Hello everyone, I need to use vTPM to finish a project but I encounter the same problem as http://lists.xenproject.org/archives/html/xen-devel/2015-06/msg03930.html
I followed the steps explained in https://mhsamsal.wordpress.com/2013/12/05/configuring-virtual-tpm-vtpm-for-xen-4-3-guest-virtual-machines/ . I'm running Ubuntu 14.04 as Dom0 on Dell. I compiled Xen 4.3.0 from source. After creating vtpmmgr and vtpm stubdoms, and DomU, I can invoke tpm_version as well as cat /sys/class/misc/tpm0/device/pcrs from DomU: However, I cannot take ownership of vTPM and thus I fail to execute the commands required ownership of vTPM. When I invoke takeownership(I set SRK password to null) I get the following error: root@tpm-guest:~# tpm_takeownership Enter owner password: Confirm password: Enter SRK password: Confirm password: Tspi_TPM_TakeOwnership failed: 0x00002004 - layer=tcs, code=0004 (4), Internal software error root@tpm-guest:~# tpm_takeownership -z -y -l debug Tspi_Context_Create success Tspi_Context_Connect success Tspi_Context_GetTpmObject success Tspi_GetPolicyObject success Tspi_Policy_SetSecret success Tspi_Context_CreateObject success Tspi_GetPolicyObject success Tspi_Policy_SetSecret success Tspi_TPM_TakeOwnership failed: 0x00002004 - layer=tcs, code=0004 (4), Internal software error Tspi_Context_CloseObject success Tspi_Context_FreeMemory success Tspi_Context_Close success I have just upgraded to Ubuntu 15.04 as the reply said but get the same error again. Could you help me handle it? Thank you very much. Best, DearFuture
