  Interacting binaries in which a white dwarf accretes material from a
companion - cataclysmic variables (CVs) in which the mass donor is a Roche-lobe
filling star on or near the main sequence, and symbiotic stars in which the
mass donor is a late type giant - are relatively commonplace. They display a
wide range of behaviors in the optical, X-rays, and other wavelengths, which
still often baffle observers and theorists alike. Here I review the existing
body of research on X-ray emissions from these objects for the benefits of both
experts and newcomers to the field. I provide introductions to the past and
current X-ray observatories, the types of known X-ray emissions from these
objects, and the data analysis techniques relevant to this field. I then
summarize of our knowledge regarding the X-ray emissions from magnetic CVs,
non-magnetic CVs and symbiotic stars, and novae in eruption. I also discuss
space density and the X-ray luminosity functions of these binaries and their
contribution to the integrated X-ray emission from the Galaxy. I then discuss
open questions and future prospects.
