TPM on Virtual machine

[BinduS]

Hi,

I have TPM chip enabled through bios on my host machine.

Now, I have a virtual machine on VM ware WorkStation running windows 2008.

I want to run Bit Locker drive encryption on this virtual machine. But my virtual machine is unable to detect tpm chip which is present on host machine.

What can i do so that the virtual machine can detect tpm chip?

Thanks,

Hima Bindu

Hi Hima,

Here are a couple of links to articles on how to enable Bitlocker inside a Vista VM:

Hope this helps you out.

Hello,

In general, no, TPM is not available to a VM. Bit Locker however may not actually talk to TPM directly as well. There is no need for it todo so. I would open up a request for feature with VMware to allow TPM within a VM within Workstation.

Hi,

So, it is not possible to use a TPM chip inside a virtual machine for bitlocker drive encryption.

Though we can run bit locker drive with USB drive, i am interested to do it with a TPM chip.

Are there any VMware products that allows to use TPM chip inside a virtual machine?

Thanks,

Hello,

Nothing I have currently seen within a VM. a Hypervisor would need to either passthru the TPM device into the VM or virtualize the TPM device. So the question becomes how would multiple VMs access teh same TPM device or should they?

So currently these questions have not been answered.
