View Full Version : Oracle announces a new product - OracleVM
I've been missing out on keeping up-to-date about Oracle's Linux suite of services and products. Recently, I visited their site again and was pleased to discover a new product - OracleVM ... extremely interesting
First a quote from the following URL
http://www.oracle.com/technologies/virtualization/index.html
Oracle VM is server virtualization software that fully supports both Oracle and non-Oracle applications, and is three times more efficient than other server virtualization products. Backed by Oracle's world-class support organization, customers now have a single point of enterprise-class support for their entire virtualization environments, including the Linux operating system, Oracle Database, Fusion Middleware, and Application software. These and other Oracle products are certified with Oracle VM, which is available for free download.
Notice I highlighted "is three times more efficient" ... now that's a huge claim. Without waiting further, I dived right in and here's what I found from the documents available
- Oracle VM is free and is available for free download from http://edelivery.oracle.com/oraclevm
- Both Linux and Windows guests are supported
- Oracle VM is free to download and use but official support can be purchased, ranging from USD$499-USD$999 per year
- Oracle VM installs directly on server hardware and does not require a host operating system
- Oracle VM supports Oracle Enterprise Linux 4 and 5, Red Hat Enterprise Linux 3, 4 and 5
- Oracle VM supports Windows 2003, Windows Server 2003 and Windows XP on HV capable hardware
- Oracle VM is the only x86-based server virtualization environment on which Oracle products are supported. Which technically means that although Oracle supports virtualization through its Unbreakable Linux Support program, Oracle products are not certified to run in the virtualization environment that comes with Oracle Enterprise Linux 5.
All very interesting ... which leads me to only one thing ... let's download and play with it :P
ok - i finally managed to download Oracle's VM [OracleVM-Server-2.1.1.iso]
installation was a breeze, very familiar interface :P
to make things simple, since its only a test machine, i accepted all the defaults.
here are some information that i gathered from the installed machine.
# cat /etc/fstab
LABEL=/ / ext3 defaults 1 1
/dev/cciss/c0d0p3 /OVS ocfs2 defaults 1 0
LABEL=/boot1 /boot ext3 defaults 1 2

proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0

# cat /etc/*release*

Yes - it looks as like its based on the sources from Red Hat and modified a little.
ok - now for part 2 - the installation of OracleVM-Manager-2.1.1.iso
as per the instructions, i did the following after I downloaded the iso to /root
# cd /root
# mount -o loop OracleVM-Manager-2.1.1.iso /mnt
# cd /mnt
# sh runInstaller.sh
oops, error found stating that libaio is not installed - its a dependency. ok, no issues, we'll have to look in /etc/yum.repos.d -- mmm, its empty. so i presume no yum now, we'll have to manually install
# cd /root/addons/
# wget ftp://194.199.20.114/linux/fedora/releases/7/Everything/i386/os/Fedora/libaio-0.3.106-3.2.i386.rpm
# rpm -ivh libaio-0.3.106-3.2.i386.rpm
re-run the installer again - oops, another error generated. this time it is stating that my / did not have sufficient space.
its looking for something more that 2.6GB and i have only 2.1GB on my /
err, in the first place, I accepted the defaults during installation, including the partitioning schema. it should have installed using a partition schema that works right?
apparently, i am wrong. even after moving OracleVM-Manager-2.1.1.iso from /root to /OVS, i only have 2.1GB on my / and they are looking for 2.6GB - however, I have tons of space on a /OVS partition. geez. now we need a little bit of creative thinking. i don't feel like reinstalling my machine. here's what i did after moving OracleVM-Manager-2.1.1.iso to /OVS
# cd /OVS
# mount -o loop OracleVM-Manager-2.1.1.iso /mnt
# mkdir disk
# rsync -avr /mnt/ /OVS/disk/
# umount /mnt
# cd disk
# cp -a runInstaller.sh runInstaller.sh.original
# vi runInstaller.sh
and in the editing of runInstaller.sh - I changed the checking of the / partition from 2.6GB to something much lower so that we will not have the error ... basically look for this
if [ "$sp3" -lt "2600000" ] ; then
echo "Disk space of dir "/" is less than 2600MB, failed ..."
exit 1
else
and change to ... less 1 ZERO :P
if [ "$sp3" -lt "260000" ] ; then
echo "Disk space of dir "/" is less than 2600MB, failed ..."
exit 1
else
installation should now work
yes - installation does work now ... after my little tweak :P
here's what i got from the installation
# sh runInstaller.sh

very nice - its all done
giving it a nice reboot once its done
after reboot, i'm faced with something unexpected.
mmm ... looking at the URLs above, its all 127.0.0.1 and the server does not have a gui installed :(
i'm not too interested in running this and seeing the UI on a command line browser. i want to see it in all its glory. so now i have to figure what i need to do to be able to access the UI through my laptop. my server has the ip address of 192.168.168.43
# cd /opt/oc4j/j2ee/home/application-deployments/ascontrol/ascontrol
# cp -a orion-web.xml orion-web.xml.original
# vi orion-web.xml
...... remove the following lines
...... <access-mask default="deny">
...... <ip-access ip="127.0.0.1" mode="allow"/>
...... </access-mask>
# cd /opt/oc4j/j2ee/home/config
# cp jms.xml jms.xml.original
# vi jms.xml
...... change
...... <jms-server port="9127" host="127.0.0.1">
...... to
...... <jms-server port="9127" host="192.168.168.43">
# service oc4j stop
# service oc4j start
# service iptables stop
now i can access http://192.168.168.43:8888/OVS/ from my laptop
installation complete.
now here are some screen caps for your pleasure
it looks like a good solution that runs XEN - the best thing about this is the fact that it has a usable GUI which is extremely commendable. i have not used this in creating an guest instances but my exploration of the GUI leads me to believe its a commendable effort and with Oracle support behind this, i'm sure it will turn some heads. maybe a relook at the installation procedures is requirement considering that i needed some quite dirty hacks to make it work
ps - all information presented in this thread are of my own personal installation experience which may differ from yours in a different environment.
