  35. Support hosting paravirtualized guest machines using the SIE
  36. virtualization capability on the mainframe. This should work
  37. on any 64bit machine.
  38. This module provides access to the hardware capabilities through
  39. a character device node named /dev/kvm.
  40. To compile this as a module, choose M here: the module
  41. will be called kvm.
  42. If unsure, say N.
