5.1.2.4.3 Creating Virtual Machines from VM Templates

After importing the template in Oracle VM Manager, you use the template to create a virtual machine.

Note:

Oracle recommends that you use Oracle VM Manager to create virtual drives of the sizes required for your system on the larger repository. Associate these virtual drives with the virtual machines deployed on your system. These virtual drives provide enough storage for installing the Exalytics software and the various files associated with the Exalytics Machine.

Before you create virtual machines, keep the following guidelines in mind:

  • Ensure that Hyperthreading is disabled on Oracle VM Server and in order to disable the hyperthreading, update the vCPUs value to 10 in the grub.conf file.

    Note:

    Oracle recommends that Hyperthreading be disabled when creating new virtual machines.

  • Maximum number of virtual machines you can create for a non-InfiniBand configuration on an X2-4, X3-4, X4-4, X5-4, and X6-4 Exalytics Machine is ten.

  • Total virtual processors (vCPUs) you can assign on Oracle VM Server for an X2-4, X3-4, X4-4, X5-4, and X6-4 Exalytics Machine is ten.

  • Total memory you can allocate on Oracle VM Server for an X2-4, X3-4, X4-4, X5-4, and X6-4 Exalytics Machine is 16 GB.

  • Review Table 5-1 for the total vCPUs and memory you can allocate on all virtual machines and the maximum vCPUs and memory you can allocate to each virtual machine.

Note:

For the X2-4 and X3-4 Exalytics Machine, total memory on Oracle VM Server (16 GB) and all virtual machines (984 GB) cannot exceed 1000 GB. For the X4-4, X5-4, and X6-4 Exalytics Machine, total memory on Oracle VM Server (16 GB) and all virtual machines (1984 GB) cannot exceed 2000 GB.

To create virtual machines from a VM template:

  1. Log on to Oracle VM Manager.

  2. Select the Servers and VMs tab.

  3. In the left pane toolbar, click Create Virtual Machine.

    The Create Virtual Machine dialog is displayed.

  4. Select Clone from an existing VM Template.

  5. Perform the following actions:

    1. In the Clone Count list, select the number of machines you want to clone.

    2. In the Repository list, select a repository for the machine.

    3. In the VM Template list, select the VM template from which you want to create the virtual machine.

    4. Enter a name for the virtual machine.

    5. In the Server Pool list, select a server pool.

    6. Enter a description for the virtual machine.

  6. Click Finish.

    The virtual machine is created and is ready to be configured.

    To configure and start a virtual machine, configure a network on a virtual machine, and configure SWAP on a virtual machine, see Maintaining Virtual Machines.
