Unfortunately, when Citrix originally released XCP, they made no effort
to make sure that XenCenter worked with XCP. So while XenCenter works
well with previous versions of XenServer, it doesn't always work well
with XCP, and especially not previous versions of XCP. The
xapi_version_override hack does help, but I'm sure that there are some
cases where it won't.

The GUI team is working to fix some XenCenter/XCP integration issues for
their next release, and the XCP team is working to make versioning
between XCP and XenServer hosts a little more sane. So hopefully this
kind of thing will quietly go away in future releases.

Hope this explains what's going on a little better.
