  18   guest networking with virtio_net. Not to be confused with virtio_net
  19   module itself which needs to be loaded in guest kernel.

  33 define KernelPackage/irqbypass/description
  34   Various virtualization hardware acceleration techniques allow bypassing or
  35   offloading interrupts received from devices around the host kernel.  Posted
  36   Interrupts on Intel VT-d systems can allow interrupts to be received
  37   directly by a virtual machine.  ARM IRQ Forwarding allows forwarded physical
  38   interrupts to be directly deactivated by the guest.  This manager allows
  39   interrupt producers and consumers to find each other to enable this sort of
  40   bypass.

  62   Support hosting fully virtualized guest machines using hardware
  63   virtualization extensions.  You will need a fairly recent
  64   processor equipped with virtualization extensions. You will also
  65   need to select one or more of the processor modules.
  66
  67   This module provides access to the hardware capabilities through
  68   a character device node named /dev/kvm.
