Hello!

For the Xen-API call tomorrow:

Here are modifications for better supporting the vTPM in the Xen API. I
took the classes for the networking (VIF) and block devices (VBD) as
examples and modeled the vTPM class similar to them. The result gives a
better approach to managing this type of device.

I thought about posting a patch for the latex source file for the
Xen-API document but had the impression that the contents of some
subsections were generated using a tool. So here are just modifications to
tables so far.

Comments are welcome.
