(that is, using OCFS 2). Fill in the values and present it to all Oracle VM Servers. In the background, you have created
two OCFS2 file systems, which are mounted to the Oracle VM Servers in the server pool:

[root@oraclevmserver ~]# mount | grep ocfs
ocfs2_dlmfs on /dlm type ocfs2_dlmfs (rw)
/dev/mapper/1IET_00010001 on /poolfsmnt/0...2b4 type ocfs2 (rw,_netdev,heartbeat=global)
/dev/mapper/1IET_00020001 on /OVS/Repositories/0...aa type ocfs2 (rw,_netdev,heartbeat=global)
[root@oraclevmserver ~]#

The cluster configuration, including all settings in /etc/ocfs2/cluster.conf , has transparently been applied by
Oracle VM Manager. Finally you can create a virtual machine. In the example, a new virtual machine based on Oracle
Linux 6 will be created as a para-virtualized guest.

■ Note oracle also offers pre-built templates for many scenarios from http://edelivery.oracle.com/linux .

Switch to the “Servers and VMs” tab and highlight your server pool in the tree on the left side of the screen.
Change the perspective to “virtual machines”, then right-click the pool and select “Create Virtual Machine”. In the
appearing wizard, enter the following information provided in Table 4-2 .

Step Information to be provided

How do you want to create
your Virtual Machine?

Create a new VM (Click “Next” to continue)

Create Virtual Machine Server: Any

Repository: your repository name
Name: OracleLinux6
Tick the box “Enable High Availability” to allow the VM to migrate to another server
in the server pool should the original host fail unexpectedly.
Description: enter an optional description
Operating System: Oracle Linux 6
Keymap: whichever suits your keyboard best
Domain Type: Xen PVM
The remaining values can be set, depending on your Oracle VM Server hardware.
A minimal installation of Oracle Linux 6 is fine with the defaults.
Click “Next” to continue to the next step.

Set up Networks Assign one or more unassigned VNIC (virtual network interface card) to the virtual

machine from the drop down labeled “unassigned VNICs”. If there are no more
VNICs, click “Create VNICs” to create some. Ensure the network is set to the virtual
machine network.

Arrange Disks Select virtual disk from the drop down menu in slot 0. Click the green plus sign in the

“Actions” column to create a new disk. It is usually a good idea to name the disk in a
way that allows you to identify it as a disk belonging to a certain VM. The size should
be at least 4 GB for a minimalistic installation of Oracle Linux 6.
