XendConfig parameters
=====================

Things that are empty means there is no direct mapping.

In order to make the XendConfig fully backwards compatible, it needs a
representation of all the below parameters. Where both columns have
values, it means we can have a direct translation.

Where the Legacy Config value does not exist, it means we have to make
up the value on whether we supported it or not.

Where the Legacy config value is prefixed with an '!', it means it is
not a direct mapping and needs a translation function.

Where the Xen API config value does not exist, it means we have to add
a parameter outside of the Xen API Configuration to support it.
