hi!
I compiled a kernel 2.6.16 as domain 0 in fc5(2.6.15). In domain 0 I
install tpm emulator simulating TPM, when I compile it, it appears as
follows:
*** Warning:
"__stack_chk_fail" [/usr/src/xen-3.0.2-2/tools/vtpm/tpm_emulator/tpm_emulator.ko] undefined!

CC /usr/src/xen-3.0.2-2/tools/vtpm/tpm_emulator/tpm_emulator.mod.o
LD [M] /usr/src/xen-3.0.2-2/tools/vtpm/tpm_emulator/tpm_emulator.ko

After I installed tpm_emulator, I insert it into kernel:
# modprobe tpm_emulator startup="clear"
FATAL: Error inserting tpm_emulator
(/lib/modules/2.6.16-xen0/extra/tpm_emulator.ko): Unknown symbol in
module, or unknown parameter (see dmesg)

Also, I have a question.
It seems tpm and tpm_emulator won't work together. I saw in xen source
code that vtpm instances make use of tpm_emulator. When I wanna to use
vtpm in xen with real tpm module, how should I do? TPM and tpm_emulator
both work as /dev/tpm0.

Thank you very much.
