Re: [libvirt] vTPM support in libvirt

I'm wondering if there will be vTPM support in libvirt in the

future?! Xen does support it already with the configuration "vtpm =
['instance=1,backend=0']", for example.
So it would be great if the libvirt XML format supported it, too... For
example like this:
<devices>
<vtpm instance="1" backend="xxx" />
</devices>
Both attributes are optional. The backend attribute is a VM ID (on Xen,
only zero for dom0 is supported) and could be implemented as a UUID?!
I'd just ignore 'backend' for now - none of the other existing devices
suport anything other than dom0 as the backend, so its no loss to assume
dom0 for TPM too.
What is 'instance' ?
For element I'd prefer to just call it '<tpm>' - the 'v' is
redundant
since every device is virtual here :-)
What do you think? Are there any efforts to introducing that?
No one has ever asked for it before, which is why we've not supported
this to date. I don't have any objection to supporting it, so patches
would be welcomed.

Daniel
