define KernelPackage/kvm-x86/description
  Support hosting fully virtualized guest machines using hardware
  virtualization extensions.  You will need a fairly recent
  processor equipped with virtualization extensions. You will also
  need to select one or more of the processor modules.

  This module provides access to the hardware capabilities through
  a character device node named /dev/kvm.

define KernelPackage/vsock-virtio/description
  Kernel support for Virtual Sockets over virtio.
  Enable this transport if you plan to run OpenWRT in a virtual machine and the
  hypervisor supports Virtual Sockets over virtio (Incus for example).

  Usually needed by "guest agents" to function, as it provides a communication
  channel between the guest os and the hypervisor.

  The module will be called vmw_vsock_virtio_transport.
