hiI am interested in vtmp, and does xen3.1 support vtpm or not? i have got a hardware platform with tpm,i want to have a try with xen vtpm ,and i want to kown wether xen3.1 support vtpm or not ?
or how to use it in xen3.1 or xen3.2 ？ Thanks Tom Buhl 写道:
Hi, yesterday I posted a question to the xen-users list concerning usage of the TPM in dom0. This is the original message: "I am using Xen 3.2.0 and want to use the TPM in dom0. I have activated vtpm and everything runs fine in my domUs. The question is, how can I access the TPM in dom0? As far as I know vtpm_managerd exclusively locks /dev/tpm0. As soon as I start vtpm_managerd my own program cannot access the TPM anymore. Is there a vtpm instance for dom0 like the ones for the user domains?" Anna Fischer replied with the suggestion to ask this list, if there has been any development recently in that direction. Is there a way to use the TPM in dom0? Thanks in advance, Tom
