Re: [Xen-devel] vTPM Manager shuts down

Hi Daniel,
Below there is the output of the "xl dmesg". I have executed "xl
debug-key q" while keeping the stubdom in pause (sleep(60)). Consider
only the last part of it, since at the beginning I have executed the "xl
debug-key q" a couple of times without having the stubdom running.
Thanks!
Jordi.
I see nothing obviously wrong here, and no obvious differences between
my tests and your configuration. You may want to look at why the mmap is
failing in the hypervisor by adding debug statements or enabling the
existing MEM_LOG statements. The error might be in get_page_from_l1e or
other functions called from do_mmu_update in xen/arch/x86/mm.c.

Hi all,
I am trying to set up the development version of Xen with support for
virtual TPMs. I am having an issue starting the vTPM Manager. Basically
I create the vTPM Manager stub domain as detailed in the documentation:
make install-vtpmmgr
dd if=/dev/zero of=/var/xen/vtpmmgr-stubdom.img bs=16M count=1
vim /etc/xen/vtpmmgr-stubdom.cfg
kernel="/usr/local/lib/xen/boot/vtpmmgr-stubdom.gz"
memory=16
disk=["file:/var/xen/vtpmmgr-stubdom.img,hda,w"]
name="vtpmmgr"
iomem=["fed40,5"]
xl create -c /etc/xen/vtpmmgr-stubdom.cfg
Nevertheless, when the stub domain is launched it automatically shuts
down (see the trace below). Am I doing something wrong? Is there
something that can produce this behaviour?
This config matches my (working) config for the vtpmmgr domain, so
there's
nothing immediately wrong here. The only differences I note are that I am
using the kernel blkback (and an LVM partition) for the disk image, which
shouldn't make any difference from the stubdom's perspective, and that I
have XSM enabled in the hypervisor (and so have a seclabel defined).

This is apparently the error, although I would expect the iomem line
to allow this mapping (-1 is EPERM, assuming it is correctly passing
the error number). Does anything appear on the hypervisor's console
(xl dmesg) that would correspond with this error?
If you can, the output of "xl debug-key q" while the domain is running
would be useful. Since it's crashing on startup, this may be difficult
to produce - changing the existing sleep(2) in stubdom/vtpmmgr/vtpmmgr.c
to a longer time should suffice. The output will go to xl dmesg, and
the lines of interest would be:

so your

For future reference, you can resolve these addresses (0x1f08a etc) using
gdb $XEN_BUILD_DIR/stubdom/mini-os-x86_64-vtpmmgr/mini-os
and then running
(gdb) x/i 0x1f08a
for each frame. That's not needed this time since the error location is
already known: HYPERVISOR_mmu_update failed.
