  sys/dev/xen/blkfront/blkfront.c:
  	On XenServer versions up to an including 6.2, paravirtualized
  	CDROM support is broken.  When running in an HVM domain,
  	ignore paravirtualized instances of CDROM media, and instead
  	rely on native drivers attaching to emulated hardware.  This
  	functions correctly on all currently known Xen based
  	platforms.
