Tools That Make Your Work with Oracle VM Easier
May 17, 2012 / By Yury Velikanov
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,

NAME ovm_vmdisks - basic Oracle VM Virtual Machine(VM) disk query utility SYNOPSIS ovm_vmdisks [OPTIONS] DESCRIPTION ovm_vmdisks is a utility designed to help the admin make backups of Virtual Machines. In particular when the Virtual Disks are files in a repository on a remote NFS server. The utility takes a Virtual Machine name or UUID and lists out every Virtual Disk file for 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. NAME ovm_vmmessage - Oracle VM Virtual Machine Message Send/Receive utility SYNOPSIS ovm_vmmessage [OPTIONS] DESCRIPTION ovm_vmmessage is a utility that allows the user to send a message to a running Virtual Machine, or to query the value of a message sent from within a Virtual Machine to the Oracle VM Management server using the Oracle VM API messaging interface. 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. ...
The following is an example of how you should run the utilities:
[root@team5lab ovm_utils]# ovm_managercontrol -u admin -p < password > -h localhost -c yuminfo Oracle VM Manager Control utility 0.5.2. Manager version : 184.108.40.2065 Connected.
