Tools That Make Your Work with Oracle VM Easier

After completing your Oracle VM and Oracle VM Manager installation (see my previous blog posts here), you are ready to start your friendship with Oracle VM technology. However, to make your life and experience even more enjoyable, I suggest you follow a few simple steps listed below.

Configure Public Oracle YUM and install additional tools:

cd /etc/yum.repos.d
wget http://public-yum.oracle.com/public-yum-el5.repo
yum install man
yum install vnc-server
yum install firefox
yum install telnet

Added on 2012.05.20

yum install strace
yum install time

After some time playing with Oracle VM, you will realize that you’ll like to manage it via command prompt and scripts. Hopefully, Oracle will come with a command line interface (cli) soon. Meanwhile, you may want to install a set of tools from Wim Coekaerts @wimcoekaerts (Oracle VM team) that would do exactly that.

MOS Patch 13602094
cd /u01/app/oracle/ovm-manager-3/
unzip /tmp/ovm_utils_0.5.2.zip
MANPATH=/u01/app/oracle/ovm-manager-3/ovm_utils/man:$MANPATH; export MANPATH

As with the patch README’s, it isn’t too obvious what these tools could do for you. I’ll provide some parts of MAN pages bellow. Helpfully after reading these, you will no longer be doubtful of whether you should install those tools or not :) For official utilities documentation from Oracle, please see Chapter 2. Using the Oracle VM Utilities from Oracle® VM Utilities Guide for Release 3.

Enjoy your Oracle VM experience,

Yury

that VM, including the Virtual Machine configuration file. This allows an admin to take the files listed in the output of the utility
and back them up to a server or tape.

If the Virtual Disks are actual physical devices directly attached to the VM, the utility lists the device mapper device of server to
which the VM is assigned. In the case of files on an NFS server, the utility lists the NFS servername, mountpoint and file name/loca-
tion.

These values are basic key/value pairs such as foo=bar. New Oracle VM templates released by Oracle contain  a  configuration  utility
called  ovmd  which  is  used to do firstboot installation configuration. Either locally from the Virtual Machine console or remotely
through this messaging interface. Ovmd also allows the owner of the Virtual Machine to send messages back to the management server.

    Hello dear,

    Would like to know if it is possible access and to backup (copy) vms on HARD DISK as partition (local) is raw with oracle vm 3 ? In order to upload in other oracle vm3 ?
    is ovm_vmdisk able to do that ?

  • Lemon says:

    Also is there a way to change ip address easily like with ovm 2
    thanks

  • Kenneth says:

    Hello.
    Is it possible to change the ovs-agent password on the pool?
    I changed the ovs-agent password on two servers belonging to a server pool, but I did it from cli, and now the servers are shown as offline.
    Thanks
