Xen Virtualization Frequently Asked Questions 

what is xvda in .cfg files of DomU ?

xvda is the first Xen Virtual Disk presented to Dom-U.

While you may name this whatever you'd like (as far as i know) it is typically one of hda, sda, xvda; if I recall, there are some performance gains by using xvda in regards to the Dom-U knowing it is para-virtualized and acting accordingly.
