This kernel module can be loaded in host kernel to accelerate |

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

be called vhost_net. |

This kernel module can be loaded in the host kernel to provide AF_VSOCK |

help |
|
This option allows vhost to support guests with a different byte |
|
ordering from host while using legacy virtio. |
|
|
|
Userspace programs can control the feature using the |
|
VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls. |
|
|
|
This is only useful on a few platforms (ppc64 and arm64). Since it |
|
adds some overhead, it is disabled by default. |
|
|
|
If unsure, say "N". |
