      5 # This machine description file is used to generate a kernel to be
      6 # used as a PV dom0 under Xen.  It is similar to GENERIC in that it is
      7 # intended to be useful for most applications.  Generally, besides
      8 # changes that are specifically required for Xen (e.g., XENPV), it
      9 # should be similar to GENERIC.  Some differences are currently
     10 # necessary, such as drivers that fail under Xen but work in GENERIC,
     11 # for reasons that do not follow from Xen architecture.
