Hello
I install 2.6.18-93.el5(contained xen3.1.2 and tpmback) which download from redhat.com to be my Dom0 and install vtpm_manager from a xen3.1.3 source packet, they work together successfully.
However there is no tpm front-end in 2.6.18-93.el5 so i manually add all the tpm related source files from xen3.1.3 packet, Makefile and Kconfig also. Some errors occur after make the kernel, so i edit the evtchn.c located in /driver/xen/core/ and make the kernel with no error.
I start DomU with vtpm configuration, run vtpm_manager in Dom0, i fail to add a tpm0 device after modprobe tpm_xenu. There is no error and no responce from the vtpm_manager. So strange.
Can anyone give me some suggestion about a workable combination of dom0 and domu with tpm front and back.
My screen shows as follow:
[root@localhost ~]# vtpm_managerd
