[Xen-users] Problems with vTPM manager

[Eduardo Peixoto Macedo <epm@xxxxxxxxxxx>]

Hi,

I am following http://xenbits.xen.org/docs/unstable/misc/vtpm.txt, but I'm having some problems when I try to start vtpmmgr-stubdom

I'm using Xen 4.3 on Ubuntu 12.04 and I have a physical TPM.

The config file for vTPM manager is:

kernel="/usr/local/lib/xen/boot/vtpmmgr-stubdom.gz"

memory=16

disk=["file:/var/vtpmmgr-stubdom.img,hda,w"]

name="vtpmmgr"

iomem=["fed40,5"]

And I get this output when I try xl create -c vtpmmgr-stubdom.cfg:
