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?!
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.
