C.5.4 Settings for creating a highly reliable network of guest domains (guest OSes) using GLS on domain-0 (host OS)

Use the settings below to create highly reliable communications on guest domains using GLS on domain-0.

  1. Set up GLS for the host OS. Setting up GLS is the same as when the virtual machine function is not used. For details, see "3.3 Additional system setup" and "Appendix B Examples of configuring system environments".

  2. Save a script to associate the virtual machine function with GLS (ethX_ethY) and a configuration file (ethX_ethY.conf) for the interfaces that NIC switching mode uses. The following is a setting example in which eth0 and eth1 are bundled. It is necessary to recognize the virtual network configuration to GLS in this step.

    # cd /etc/opt/FJSVhanet/script/xen
    # cp -p eth_eth.xen.sam eth0_eth1
    # cd /etc/opt/FJSVhanet/script/conf
    # cp -p eth_eth.conf.sam eth0_eth1.conf
  3. Set up a script to associate the virtual machine function with GLS (ethX_ethY.conf). Set the primary interface's virtual bridge name in PRI_BR=, and set the name of the external connection interface in PRI_OUT_IF=. In addition, set the secondary interface's virtual bridge name in SEC_BR=, and set the name of the external connection interface in SEC_OUT_IF=.

    PRI_BR=xenbr0
    SEC_BR=xenbr1
    PRI_OUT_IF=peth0
    SEC_OUT_IF=peth1
