Installation Overview
Oracle VM uses an Oracle database as a repository. Oracle VM production deployments require Oracle Database Standard Edition (Oracle SE) or Enterprise Edition (Oracle EE). If you are testing Oracle VM and do not require a supported product, you can use Oracle Database Express Edition (Oracle XE). Oracle XE is not a supported product, and Oracle Support Services cannot supply patches for it. If you require full support from Oracle, you should use Oracle SE or EE as the Oracle VM database repository.
Oracle VM Manager can be installed in a demo installation using Oracle XE, or as a production installation using Oracle SE or EE. The demo installation installs Oracle XE on the local host and configures it to use as the repository. The production option collects information on the pre-installed Oracle Database and uses it as the repository. In both install types, Java, the Oracle VM Manager application, and Oracle WebLogic Server are installed on the local host.
An uninstaller is included with the installation script. The uninstaller gives you options to remove Oracle XE, Java, the Oracle VM Manager application, and the Oracle WebLogic Server.
Oracle VM Manager Components
The applications necessary to run Oracle VM Manager are packaged in the ISO image. Some or all of the following applications may be installed on the host computer when you install Oracle VM Manager:- Oracle VM Manager
- The Oracle VM Manager application provided as a Oracle WebLogic Server domain and container.
- Oracle WebLogic Server 11g
- Oracle WebLogic Server Release 11g,
including Application Development Framework (ADF) Release
11g. For more information about Oracle
WebLogic, see the
Oracle
WebLogic 11g documentation.
Use of Oracle WebLogic Server with Oracle VM Manager is restricted to the servlet functionality without clustering for the Oracle VM Management Server. - Oracle Database
- In a new installation, Oracle Database
11g Express Edition (Oracle XE) for
Linux 64-bit may be installed. If Oracle XE is already
installed, the installer asks whether it should use the
existing database, install a new one, or use another
database in the local area network (LAN). For more
information about Oracle XE, see the
Oracle
Database Express Edition Documentation for 11g
Release 2 (11.2).
You should only use the Oracle XE database as the Oracle VM Manager repository in non-production environments. Oracle XE is not a supported product and Oracle Support Services cannot provide bug fixes or patches for this product. If you are deploying Oracle VM Manager in a production environment, you should use Oracle Database Standard or Enterprise Edition, which you must install separately to Oracle VM. Oracle VM Manager includes a restricted-use license of the Oracle Database (Standard Edition or Enterprise Edition) for use as the Oracle VM Manager Management Repository only. The supported version of Oracle Database are:
- Oracle Database Release 10.2.0.4 or greater
- Oracle Database Release 11.1.0.7 or greater
- Oracle Database Release 11.2.0.1 or greater

Prerequisite Packages
libaio
If your computer is configured with Oracle Unbreakable Linux Network (ULN) you can run either of the following commands to update or install libaio, whichever is appropriate for your system:
# yum install libaioor
# up2date libaioYou can also find the libaio package on the Oracle Linux DVD or ISO file. To install libaio, go to the directory where the libaio.rpm is located, and enter the command:
# rpm -ivh libaio-version.rpm
To upgrade libaio, you can use the command:
# rpm -Uvh libaio-version.rpm
unzip
# yum install unzip
bc
# yum install bc
Firewall Configuration
The ports required for the web browser connection to Oracle VM Manager are: 7001, 7002 and 15901. The ports used by the Oracle VM Servers to connect to Oracle VM Manager are: 7001, 7002, and optionally 54321 and 54322 for remote API access. Oracle VM Manager, in turn, connects to the Oracle VM Servers through port 8899 for Oracle VM Agent communication, and port 6900 and up for secure VNC tunneling to virtual machines (one port per VM). Be sure to open the necessary ports on the different firewalls that may be installed between different parts of your network. Follow the guidelines of in the diagram below:
To disable iptables and open all ports, enter the following commands as the root user:
# service iptables stop # chkconfig iptables offAlternatively, open the required ports by using the iptables command as the root user:
# iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 7001 -j ACCEPT # iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 7002 -j ACCEPT # iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 15901 -j ACCEPT # iptables -A INPUT -m state --state NEW -m udp -p udp --dport 123 -j ACCEPTTo remotely connect to the Oracle VM Manager core API, also enter the following command:
# iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 54321 -j ACCEPT # iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 54322 -j ACCEPTWhen all the ports have been opened, save the iptables configuration:
# service iptables saveThis does not require iptables to be restarted as the commands open the ports while iptables is running and the save ensures they are opened on reboot/restart in future.
To configure the firewall to open the required ports automatically, use the environment configuration script provided with the Oracle VM Manager installer. See Section 3.3.2.4, “Environment Configuration Script” for information on using this script.

If you want to install Oracle VM Manager in a virtualized environment, do
not install it on Oracle VM Server (dom0) directly; install it into a
virtual machine running on an Oracle VM Server. For more information,
see Section 3.7, “Running Oracle VM Manager as a Virtual Machine”.
Mounting the Oracle VM Manager Installation Media
-
To install Oracle VM Manager from a CD, burn the Oracle VM Manager ISO file to
a CD. Insert and mount the Oracle VM Manager CD using the following
commands:
# mkdir
Where mount-point refers to the directory on which you mount the ISO file.mount-point# mount /dev/cdrommount-point -
To install Oracle VM Manager from a hard drive, locate the folder
that contains the ISO file. Mount the ISO file to an
existing directory using the following commands:
# mkdir
Where mount-point refers to the directory on which you mount the ISO file. For example:mount-point# mount -o loop OracleVM-Manager-version.isomount-point
# mkdir /OVMCD # mount -o loop OracleVM-Manager-3.
You can find all the mounted files under the directory /OVMCD.x.x.iso /OVMCD
NoteThe location of the mounted Oracle VM Manager ISO file should be accessible by the oracle user.
Running the Oracle VM Manager Installer

Configuring the NTP Service
However, to provide time services to the Oracle VM Servers, NTP must first be installed and configured on the Oracle VM Manager host server. Make sure that your Oracle VM Manager host is either registered with the Unbreakable Linux Network (ULN) or configured to use Oracle's public YUM service.
To configure NTP on the Oracle VM Manager host:
-
Install the NTP package.
# yum install ntp
Once NTP is installed, configure it to both synchronize with upstream servers and provide time services to the local network, where the Oracle VM Servers reside. -
Enable upstream synchronization by defining the upstream
time servers in the
ntp.conffile.
Oracle Linux uses three public NTP servers as upstream time sources by default. Check with your network administrator if time services are provided on the corporate network and, if necessary, replace the default entries with the names or IP addresses of your NTP servers.
Use your favorite text editor to modify/etc/ntp.conf. Search for these entries:# vi /etc/ntp.conf server 0.rhel.pool.ntp.org server 1.rhel.pool.ntp.org server 2.rhel.pool.ntp.org
-
Configure downstream access for the Oracle VM Servers in your local
network. To do so, disable the default
"noquery"option for the Oracle VM Server management network.
Again in the/etc/ntp.conffile, search for this entry:#restrict
Replace192.168.1.0mask255.255.255.0nomodify notrap192.168.1.0with the network address of your Oracle VM Server management network. You may also need to adjust the netmask (255.255.255.0). Remove the # character at the start of the line to uncomment this entry. Once you have finished editing, save the/etc/ntp.conffile. -
Start the NTP service and set it to launch automatically
upon boot.
# service ntpd start # chkconfig ntpd on
-
When NTP is running, check upstream synchronization. The
ntpqcommand should output something similar to this example:# ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== lists2.luv.asn. 203.161.12.165 16 u 25 64 3 3.495 -3043.1 0.678 ns2.novatelbg.n 130.95.179.80 16 u 27 64 3 26.633 -3016.1 0.797 sp1.mycdn.fr 130.234.255.83 16 u 24 64 3 4.314 -3036.3 1.039When upstream NTP is working properly, delay and offset values should be non-zero and the jitter value should be below 100. -
Test downstream synchronization from another server in the
management network to ensure that NTP services are working.
Note that it may take several minutes before your NTP server
is able to provide time services to downstream clients.
Begin by checking the stratum level of
your server:
# ntpq -c rv assID=0 status=c011 sync_alarm, sync_unspec, 1 event, event_restart, version="ntpd 4.2.4p8@1.1612-o Tue Jul 6 21:50:26 UTC 2010 (1)", processor="x86_64", system="Linux/2.6.32-200.19.1.el6uek.x86_64", leap=11,If the server is showingstratum=16, precision=-20, rootdelay=0.000, rootdispersion=1.020, peer=0, refid=INIT, reftime=00000000.00000000 Thu, Feb 7 2036 17:28:16.000, poll=6, clock=d21d4a96.a26c5962 Fri, Sep 16 2011 14:09:58.634, state=0, offset=0.000, frequency=0.000, jitter=0.001, noise=0.001, stability=0.000, tai=0stratum=16, wait a few minutes and try again. It may take up to 15 minutes for an NTP server to stabilize sufficiently to lower its stratum level.
Downstream clients will not synchronize with a server at stratum level 16. Once the stratum level has dropped, log in to any available Linux host in your management network and issue the following command:# ntpdate -d
This command runs ntpdate in debug mode, in which case the availability of the remote time server is checked. If the debug run ends in a line similar to the one in this example, the test is successful. In case the stratum level is still too high, the error messagemanager.hostname[...] 16 Sep 13:58:25 ntpdate[1603]: step time server 192.168.1.1 offset 3.009257 sec"Server dropped: strata too high"is displayed.
Caution
NTP communicates over UDP port 123. Ensure that no firewall is
blocking this traffic.
Installing and Configuring a VNC Viewer
Any firewall between the client and Oracle VM Manager needs port 15901 to be open. Any firewall between the Oracle VM Manager and the Oracle VM Servers needs ports 6900 and above open; one port for each virtual machine on an Oracle VM Server. For example, if you have 100 virtual machines on an Oracle VM Server, you should open ports 6900-6999 (100 ports) on any firewall between the Oracle VM Server and Oracle VM Manager.
To connect to a virtual machine's console in Oracle VM Manager, you should have a VNC viewer installed somewhere in your environment, either:
- On the Oracle VM Manager host computer
- On the client computer
- On both the Oracle VM Manager host computer and the client computer
It is preferred that you install either TightVNC on the Oracle VM Manager host computer. You can get the latest TightVNC package from:
http://oss.oracle.com/oraclevm/manager/RPMS/
Install TightVNC with the command:
# rpm -ivh tightvnc-java-version.noarch.rpm
On the client computer you use to connect to Oracle VM Manager
it is recommended that you install RealVNC. Oracle recommends
RealVNC on the client computer as it renders quickly, has better
keyboard support, and has less mouse control issues compared to
other VNC clients. The RAS proxy applet used to view the screen
or console of a virtual machine looks for RealVNC by default. If
you have multiple VNC viewers on your client computer, you can
configure which one is used from the virtual machine console in
Oracle VM Manager. See
Connecting to a Virtual Machine for more
information on using and configuring the VNC client.
If you are using a Linux-based operating system on your client computer, you can also install TightVNC as above on your client computer and it is automatically discovered when you connect to a virtual machine using the console feature in Oracle VM Manager.
