|

# 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.

||||
