How to install Oracle VM manager on Oracle Linux ?

Oracle VM manager provides graphical web-based interface to administrate network , storage infrastructure of oracle VM servers.It provides a centralized management environment for oracle VM servers and oracle VM for SPARC environments.Since it provides  web interface, you can manage the oracle VM servers from anywhere .To install oracle VM manager , you need  oracle enterprise linux operating system . Oracle VM manager applications  uses oracle database  and weblogic software .This oracle VM manage is similar to VMware vCenter server.You can see the Oracle VM and VMware vSphere comparison. Here we will see how we can deploy the oracle VM manager on oracle Enterprise linux operating system

Requirement :

1. Operating system – Oracle enterprise Linux 6
2. Physical Memory – 8GB
3. CPU – 1
4. Disk free space – 10GB
5. Oracle VM Manager software . ( It can be freely downloaded from oracle website)

1. Login  to the oracle enterprise Linux 6  as root user.

2.Download the oracle VM manager software from oracle and mount the ISO using below commands.

[root@UA-OVM ~]# cd Desktop/
[root@UA-OVM Desktop]# mount -t iso9660 -o loop V29653-01.iso /mnt
[root@UA-OVM Desktop]# df -h /mnt

7.Once the installation is completed, you need to validate the Oracle Linux firewall settings. By default , it blocks everything . You can run the below command to flush the iptables.This change will not persist across the server reboot.

[root@UA-OVM mnt]# iptables -F
[root@UA-OVM mnt]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
[root@UA-OVM mnt]#

8.To disable iptables permanently across the system reboot, use the below set of commands.

# /etc/init.d/iptables save
# /etc/init.d/iptables stop
# chkconfig iptables off

9.Now you can access the OVM console from web-browser using below URL from any system if you have network connectivity.

  http://UA-OVM:7001/ovm/console
  https://UA-OVM:7002/ovm/console

10.Here is the login console for OVM manager.

11.OVM home page will looks something like below one.

Oracle VM manager installation is very easy.Oracle has integrated their top softwares like oracle Database,Weblogic with  oracle VM manager.From here you can add the oracle VM  servers and create a server pool for virtual machines provisioning.We will see those things in upcoming articles. Stay tuned.
