      Table 5-13 VLAN for System VM

      VLAN Name VLAN ID (example)
      OAM/Mgt 1982
      XMI 1983
      IMI 405
      INT 406
      According the architecture OAM & XMI could be a unique VLAN.
    4. Create bond0.<vlan> OAM/Mgmt interface configuration file (/etc/sysconfig/network-scripts ifcfg-bond0.<vlan>):

    $ sudo vi /etc/sysconfig/network-scripts/XMI
    DEVICE=br_XMI
TYPE=Bridge
BOOTPROTO=none
ONBOOT=yes
NM_CONTROLLED=no

    Note:

    Repeat this step for all identify interfaces. For IDIH, we need XMI,IMI and INT interfaces.
  18. Create VLAN interfaces and bond them to the appropriate bridge.
    Create guests XMI vlan interface (/etc/sysconfig/network-scripts ifcfg-bond0.<XMI Vlan>)
    $ sudo vi /etc/sysconfig/network-scripts/ifcfg-bond0.1983
    ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
VLAN=yes
BRIDGE=XMI
TYPE=Ethernet

    Note:

    Repeat above step for all identify interfaces. For IDIH, we need XMI,IMI and INT interfaces.
  19. Verify interfaces and restart the network.
    1. Verify that all interfaces have been created with ls command.
      $ sudo ls -l /etc/sysconfig/network-scripts/

      Example:
      example

    2. Execute the following:
      $ sudo service network restart
  20. Create image repository.
    1. Verify disk space.
      $ df –h
    2. Create an images directory called repository for IMGs and ISOs in /home partition.
      $ cd /home
$ sudo -i
$ mkdir repository
  21. Copy image to the repository on the management server.
    Copy one of the two image types to the .qcow2 directory created.

    Note:

    • The image pack for OCPM is located on the Oracle Software Delivery Site.
    • Copy IDIH Oracle,Mediation and application images to the repository.
  22. Launch the virtual manager from the ILOM console.
    virt-manager from the OS (virt-manager and its dependencies are included in Oracle Linux ISO and installed on the host).
    VMM

  23. Resize ORA (database) ova image on KVM.
    1. Resize ova from KVM to 120G. Run the following commands:
      cd /home/repository/qemu-img resize <image_name.qcow2> +<New_Size>
      cd /home/repository qemu-img resize ORA-82_32_0.qcow2 +56G
    2. Verify actual size.

      Apply command, virtual size to 120G.

      [root@MXMERM01DRA01S05KVM03 repository]# qemu-img
info ORA-82_32_0.qcow2
image: ORA-82_32_0.qcow2
file format: qcow2
virtual size: 120G (68719476736 bytes)
disk size: 20G
cluster_size: 65536
Format specific information:
    compat: 1.1
    lazy refcounts: false
[root@MXMERM01DRA01S05KVM03 repository]#

  25. Create VMs using .qcow2 image.
    1. Click Add Hardware, select Network.
      GUI

      Interfaces for IDIH VMs:

      Oracle: XMI and INT

      Mediation: XMI, INT and IMI

      Application: XMI and INT

      Note:

      Ensure that all 3 IDIH VMs are created and corresponding interfaces have been added to them (as listed above). The interfaces naming convention XMI, IMI, INT must be used in place of eth0, eth1, eth2. This change must be done in 70-persistent-net.rules file. Check HWaddr of each interface using ifconfig command and edit the file to change interface names accordingly. Ensure that interface names are not interchanged while editing the file. Caution is advised.

      Table 5-14 IDIH VM Interfaces

      IDIH VM interfaces
      XMI eth0
      IMI eth1
      IN eth2

      PARAMETERS:

      Network source = XMI (select appropriate network source from the dropdown)

      Device Model = virtio
