Oracle VM Server x86: Installing Oracle VM Manager

First check the hardware requirements:

After downloading the right image (please do not laugh, this is really a problem), inside a Oracle Linux the following steps have to be done:

mount /dev/cdrom /mnt
mount: /dev/sr0 is write-protected, mounting read-only

and

# ls /mnt/
components       oracle-validated.params  OvmSDK_3.4.4.1709.zip  sample.yml
createOracle.sh  ovmm-installer.bsx       runInstaller.sh        TRANS.TBL

First try:

[root@localhost ~]# /mnt/createOracle.sh
Missing required package, Oracle VM Manager requires 'iptables-services' to be installed, you can use 'yum install iptables-services' to install it.

Ok:

[root@localhost ~]# yum install iptables-services

And here we go:

# /mnt/createOracle.sh

Before starting the "runInstaller.sh" i had to install the following packages:

But then:

[root@localhost ~]# /mnt/runInstaller.sh
