This made me look at th domain creation paths again, and it seems as if
the parameter settings for HVM guests is split in an awful way: the
console ring page pfn is set from libxenguest, while the console event
channel is set from libxl only. :-(

This means that this patch can be dropped, while init-xenstore-domain
needs to gain another one.

Thanks for your feedback,
