How to Install Oracle VM Manager 3.4.2

For simplifying our procedures, I have to assume that you have installed Enterprise Linux 6.7 minimal on the server. The hardware requirements to install OVMM 3.4.2 safely is as of:
  • 8GB memory or above: Any figure lower than 8GB will meet errors during installation.
  • 40GB disk space or so.

A. Configure file hostname resolution.

The name resolution is pretty important for setting up an Oracle VM environment by Oracle VM Manager (OVMM) later.
[root@ovmm ~]# cat /etc/hosts
...
192.168.10.20   ovmm ovmm.example.com
192.168.10.21   ovs1 ovs1.example.com
192.168.10.22   ovs2 ovs2.example.com

B. Install required packages.

Since we were installing a minimal version of Linux, there’re some packages required to make us go further.
[root@ovmm ~]# yum -y install zip unzip perl numactl ntp libaio

C. Mount OVMM ISO file

After that, please mount the ISO ovmm-3.4.2-installer-OracleLinux-b1384.iso on cdrom of this server.
[root@ovmm ~]# mount /dev/cdrom /media
mount: block device /dev/sr0 is write-protected, mounting read-only

Another approach is to mount the uploaded ISO file directly to utilize the content.

D. Install OVMM 3.4.2

Installing OVMM 3.4.2 is actually a two-step procedure, one is creating accounts and allocating resources, the other one is installing the software. Let’s take a look the first step.
[root@ovmm ~]# cd /media
[root@ovmm media]# ./createOracle.sh

Now, we can begin the installer.
[root@ovmm media]# ./runInstaller.sh
