# Node ID 51f521303df7c85a7e67a6f543e388530f40b552

[vTPM] Add set/get_other_config to Xen-API.
Add get_- and set_other_config methods to the vTPM class. Write the
parameters into the xenstore while the domain is running prefixing it
with 'oc_'. Also I add the methods to the C library as well as the
documentation.
