[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-users] some problems to start vTPM vtpm-stubdom
Hi community,
there are some problems to start vTPM vtpm-stubdom following
docs/misc/vtpm.txt. When I start vtpm-stbdom, the vtpmmgr-stubdom will print
out:
===
ERROR[VTPM]: LoadKey failure: Unrecognized uuid!
69743ae0-9d4a-4ad6-9819-e602085b6792
ERROR[VTPM]: Failed to load key
ERROR in vtpmmgr_LoadHashKey at vtpm_cmd_handler.c:78 code: TPM_BAD_PARAMETER.
===
I start vtpmmgr-stubdom with vtpmmgr.cfg as below:
====
kernel="/usr/lib/xen/boot/vtpmmgr-stubdom.gz"
memory=16
disk=["file:/var/vtpmmgr-stubdom.img,hda,w"]
name="vtpmmgr"
iomem=["fed40,1"]
====
It prints out with below:
