# This example script creates bonding network devices based on synthetic NIC
|
|
# (the virtual network adapter usually provided by Hyper-V) and the matching
|
|
# VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can
|
|
# function as one network device, and fail over to the synthetic NIC if VF is
|
|
# down.
|
|
#
|
|
# Usage:
|
|
# - After configured vSwitch and vNIC with SRIOV, start Linux virtual
|
|
# machine (VM)
|
|
# - Run this scripts on the VM. It will create configuration files in
|
|
# distro specific directory.
|
|
# - Reboot the VM, so that the bonding config are enabled.
|
|
#
|
|
# The config files are DHCP by default. You may edit them if you need to change
|
|
# to Static IP or change other settings.
|
