  26 # Modified to run on grub2 and efi boot
  27
  28 # Personalize RHEL7.2 on compute nodes
  29 # Prepared to work with the following network card drivers:
  30 #       tg3, igb drivers for management interfaces
  31 #       ixgbe (Intel Niantic) and i40e (Intel Fortville) drivers for data plane interfaces
  32
  33 # To download:
  34 # wget https://raw.githubusercontent.com/nfvlabs/openmano/master/scripts/configure-compute-node-RHEL7.1.sh
  35 # To execute:
  36 # chmod +x ./configure-compute-node-RHEL7.1.sh
  37 # sudo ./configure-compute-node-RHEL7.1.sh <user> <iface>
  38
  39 # Assumptions:
  40 # All virtualization options activated on BIOS (vt-d, vt-x, SR-IOV, no power savings...)
  41 # RHEL7.2 installed without /home partition and with the following packages selection:
  42 # @base, @core, @development, @network-file-system-client, @virtualization-hypervisor, @virtualization-platform, @virtualization-tools
  43
  44 # 2016 Aug 17 Antonio López
  45 # Changed virbrInf to virbrVIM, to reflect that this bridge is used to communicate with the VIM (OpenVIM)
  46 # Changed the vlan tag used by virbrVIM from 2000 to 1100
