How to Install OVM Oracle VM Manager on Linux

by Ramesh

Oracle VM Manager is required to manage one or more Oracle VM Server. This tutorial, explains high-level steps on how to install and configure Oracle VM Manager. In this example, I’ve used the current stable version of OVM 3.2.2. But, the steps are pretty similar for other OVM versions.

1. Perform OVM Manager Pre-Req

Before you install OVM Manager, you need to perform the following pre-req:

  • Create required oracle user, dba group
  • Create /u01 directory and set appropriate permissions
  • Update the limits.conf file
  • Add appropraite iptables rules

Instead of doing this manually one-by-one, you can simply execute the createOracle.sh shell script that comes with the Oracle VM Manager Installation CD, which will automatically take care of the above pre-reqs as shown below.

# sh createOracle.sh
Adding group 'oinstall' with gid '54321' ...
Adding group 'dba'
groupadd: group 'dba' already exists
Adding user 'oracle' with user id '54321', initial login group 'dba', 
    supplementary group 'oinstall' and  home directory '/home/oracle' ...
User 'oracle' already exists ...
uid=500(oracle) gid=502(dba) groups=502(dba)
Creating user 'oracle' succeeded ...
Verifying user 'oracle' OS prerequisites for Oracle VM Manager ...
oracle  soft    nofile          8192
oracle  hard    nofile          8192
oracle  soft    nproc           4096
oracle  hard    nproc           4096
oracle  soft    core            unlimited
oracle  hard    core            unlimited
Setting  user 'oracle' OS limits for Oracle VM Manager ...
Altered file /etc/security/limits.conf
Original file backed up at /etc/security/limits.conf.orabackup
Verifying & setting of user limits succeeded ...
Changing '/u01' permission to 755 ...
Modifying iptables for OVM
Adding rules to enable access to:
     7002  : Oracle VM Manager https
     15901 : Oracle VM Manager VM console proxy
     54321 : Oracle VM Manager core
     54322 : Oracle VM Manager core via SSL
       123 : NTP
     10000 : Oracle VM Manager CLI Tool
iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]
Rules added.

In my case, since this was a test machine, I had some other issues connecting to the Oracle VM Server, because of some existing firewall rules. I temporarily disabled those to make sure I get the basics working, before I can debug the firewall rules and fix the issue. If you like to do the same, stop the iptables and ip6tables as shown below.

# service iptables stop
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Unloading modules:                               [  OK  ]

# chkconfig iptables off

# service ip6tables stop
ip6tables: Flushing firewall rules:                        [  OK  ]
ip6tables: Setting chains to policy ACCEPT: filter         [  OK  ]
ip6tables: Unloading modules:                              [  OK  ]

# chkconfig ip6tables off

2. Install Oracle VM Manager

Next, from the Oracle VM Manager Installation CD, execute the runInstaller.sh which is a text based installation utility, which will ask you few questions before it installs OVM.

First, select the installation type. Choose “Simple”.

# ./runInstaller.sh

Oracle VM Manager Release 3.2.2 Installer

Oracle VM Manager Installer log file:
/tmp/ovm-manager-3-install-2013-05-08-073627.log

Please select an installation type:
   1: Simple (includes database if necessary)
   2: Custom (using existing Oracle database)
   3: Uninstall
   4: Help

   Select Number (1-4): 1

You might get the following warning message about the required memory (Which is 8GB). In my example, I had only 4GB RAM, I ignored the warning message, and everything worked as expected without any issues. So, 4GB memory is good enough to get this working.

Starting production with local database installation ...

Verifying installation prerequisites ...
*** WARNING: Recommended memory for the Oracle VM Manager server installation using Local MySql DB is 7680 MB RAM

This will also prompt you for the password that you’ll be using for all the installations. This password will be used for Oracle VM Manager, database settings, and weblogic servers. So, don’t forget his password. Later if you like you can go-ahead and change all these password to different ones. But, during installation you have to specify one common password for all these components.

One password is used for all users created and used during the installation.
Enter a password for all logins used during the installation:

Final confirmation before it starts the installation. Select “Continue”.

   1: Continue
   2: Abort

   Select Number (1-2): 1

3. Verify Installation

Now, to verify the installation, login to the OVM Manager GUI as shown below. The username is admin and the password is the one you specified in the above installation steps.

https://{ip-address-of-ovm-manager-server}:7002/ovm/console

Once you login to OVM Manager, you’ll see a page with the following tabs:

  • Health
  • Servers and VMs
  • Repositories
  • Networking
  • Storage
  • Tools and Resources
  • Jobs

4. Post Installation Cleanup

After the installation, delete the cat /tmp/ovm_config* file, which was created by the installater, which might contain some sensitive information.

# cat /tmp/ovm_configtVDoJT
ADF: {fromUrl: 'file:///mnt/components/ofm_appdev_generic_11.1.1.5.0_disk1_1of1.zip',
  install: 'Yes'}

  install: true, options: '-Xms512m -Xmx1024m -XX:MaxPermSize=256m',
  user: weblogic}

# rm /tmp/ovm_configtVDoJT

Install log files as under /tmp as shown below.

# ls -l /tmp/ovm-manager*
-rw-r--r--. 1 root root     7071 May  8 23:27 /tmp/ovm-manager-3-install-2013-05-08-232653.log

5. OVM Manager Components

As part of the OVM Manager installation, the following components are installed in the location specified below.

  • MySQL /u01/app/oracle/mysql/data
  • MySQL Enterprise Backup /opt/mysql/meb-3.8/
  • MySQL Backup Location /u01/app/oracle/mysql/dbbackup
  • Java /u01/app/oracle/java
  • Oracle WebLogic Server 11g /u01/app/oracle/Middleware/
  • Oracle ADF /u01/app/oracle/Middleware/
  • Oracle VM Manager application /u01/app/oracle/ovm-manager-3/
  • Oracle WebLogic Server domain /u01/app/oracle/ovm-manager-3/machine1/base_adf_domain

6. Start and Stop OVM Manager

Oracle VM Manager service is called ovmm. Use the service command to check the status, or stop, or start the service as shown below.

# service ovmm status
Oracle VM Manager is running...

# service ovmm stop

# service ovmm start

# chkconfig --list ovmm
ovmm            0:off   1:off   2:on    3:on    4:on    5:on    6:off

5. Troubleshooting

Issue: During the OVM installation, you might get the following error message:

Verifying installation prerequisites ...
Unable to ping hostname 'ovm-manager'.
Configuration verification failed ..

Solution: Make sure to add the ovm-manager to the /etc/hosts file on the server as shown below, and try the installation again.

# cat /etc/hosts
127.0.0.1   ovm-manager localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

Stay tuned! We’ll be posted more articles on OVM on an on-going basis.
