[libvirt] vTPM support in libvirt

[Andreas Sommer]

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

What do you think? Are there any efforts to introducing that?

Cheers
