Oracle VM Manager
Oracle VM Manager
A powerful virtual manager is essential for businesses who seek stability for their online or local applications. With a reliable virtual manager, developers will be able to partition the server capacity in order to properly distribute support for each user. Stability of each user is highly possible even though network administrators use a single server for various servers.
One of the most sought after server virtualization tool was developed by Oracle. The Oracle Virtual Manager is a free virtualization tool and it has become the standard for many web developers and system administrators. The tool is powerful enough for any business setting but simple enough for many administrators and web developers to understand. This book aims to explain the basics of Oracle Virtualization Manager while slowly delving into the specific functions that could help businesses in their server virtualization needs.

Oracle VM Manager 2.1.2
Oracle VM Manager is a management product developed by Oracle that complements Oracle Grid Control and fits into Oracle s Cloud Computing strategy. Oracle VM Manager is a rather new product and is gaining popularity within the Oracle community especially within groups that have been testing Oracle products in sandbox environments using alternate VirtualizationOracle VM Management
We ll begin this chapter by looking at the meaty aspects of the Oracle VM Manager and will explore it s management aspects. The following topics will be covered in this chapter Getting started with the Oracle VM Manager Managing Servers and Server Pools Managing Oracle VM Server repository Users and Groups management BackingLogging in to Oracle VM Manager
Again we will need to either access the URL locally by typing http 127.0.0.1 8888 OVS or by typing the following http hostname 8888 OVS. If we are accessing the Oracle VM Manager Portal remotely replace the hostname" with either the FQDN Fully Qualified Distinguished Name if the machine is registered in our DNS or just the hostnameOracle VM management: Managing Server Pool
A Server Pool is logically an autonomous region that contains one or more physical servers and the dynamic nature of such pool and pools of pools makes what we call an infinite Cloud infrastructure. Currently Oracle has its Cloud portal with Amazon but it is very much viable to have an IntraCloud portal or private Cloud where we can run all sortsArchitectural decisions around designing Server Pools
This section will not only guide us but also help us make the right architectural decisions around choosing the type of Server Pool for our Data Center. Designing a Data Center brings several challenges. Knowing how to not only architecturally design but also to orchestrate their roles within the substrate with embedded Oracle VM virtualization helpsOracle VM Manager: Server Pool Creation
Server Pool Creation We have had a quick look at the servers that we can add to the Server Pool but we haven t seen how to create one. So let s go ahead and do that. To create a Server Pool click on the Create Pool button on the Server Pool s page on the top-right corner of the page. As mentioned let s go ahead and login to the Oracle VMOracle VM Manager: Editing Server Pool Information
We can make several changes to the Server Pool such as changing the Server Pool name managing servers and adding or removing users. Let s start by editing the Server Pool To select our Avastu Pool we can click on the Servers and Users link and edit the Servers and Users. Both of those will be tackled later in this chapter. For instance ifOracle VM Manager: HA Fundamentals and Enabling HA
HA fundamentals and enabling HA HA is a crucial part of our Data Center strategy and it is crucial because hardware failure is inevitable. It is important to prevent disruption of service and ensure business continuity. When an Oracle VM Server is restarted the VMs resting on it are either restarted or migrated to other available hosts. The managementOracle VM Management: Managing VM Servers and Repositories
There must be at least one physical server in the Server Pool that we have created. There are many things you can do with the VM Servers in the Server Pool such as changing the configurations or role or function of the server restarting it shutting it down monitoring its performance or even deleting it. The Server Pools are elastic and can adaptOracle VM Manager: Editing Server information
In order to update information on an existing Oracle VM Server click on Edit. We can alternatively also click on the General Information tab. To monitor the performance of the Oracle VM Server we can click on the Monitor tab where we get real time access to CPU memory and storage usageOracle VM Manager: Restart, Shutdown and Delete Servers
It is easy to remotely manage the Oracle VM Server. We could be anywhere in the world and we can carry out the restart shutdown and unfortunately delete the Server operations from a distance. So such an opportunity to manage large Oracle IntraCloud farms from a distance is a great deal given that the ever-increasing need to be able to provideOracle VM Manager: About Managing Repositories
Here we will explore the possibilities of managing Oracle VM repositories. What are exactly Oracle VM repositories A repository is used for live migrations of VMs and local storage. They are normally found under etc ovs repositories Adding or removing the repository can be done by firing up the ovs-makerepo script and ovs-offlinerepo scriptOracle VM Manager: User and Group Management
Here we will explore how to manage users and groups and will divide the section into the following two parts Managing Users Managing Groups This function is only available to administrators so use this role prudently. During the installation of the Oracle VM Manager a default admin account is created. And with this admin s accountOracle VM Manager: Viewing or Editing VM User
Now let s view the User we just created. 1. Click on the User tab on the Administrator page 2. Click on the Show link to view the Server Pools that the user is allowed to use We can now edit account details such as change email address change account status and so on. 1. Let s change the User s email address 2. Modifying the accountOracle VM Manager: Changing a User's Role
Lets change regular Users role to Administrator 1. On the Administrator s page select the newly created User and click on the Edit button. 2. Select the role and click Apply to effectively assign the role to the User 3. Once applied we will be presented with the following screen Deleting User To delete a User we need to do theOracle VM Manager: Managing Groups
Creating Groups in Oracle VM Manager is a convenient way to manage the endless number of users. It can be a very exhaustive task to assign privileges to the users and thus it is better to create groups for specific functions. That way we can copy users to those groups implying that all of the users can have the specific group functions that are designedOracle VM Manager: Adding, Editing, Deleting Group Users
Adding Users to a Group Perform the following steps to add users to the group 1. On the Administration page click on the User tab. 2. Select search users that you want to add to this group and click Edit. 3. In the Group s section click the group under Available Groups column and move it to the Selected Groups column. 4. Click on the ApplyOracle VM Manager: Backing Up
Before uninstalling moving the VM Server from one location to another OR any other major change we would want to backup the Oracle VM Manager. Let s learn how to back up and restore the Oracle VM Manager. Backing up Oracle VM Manager Ensure that all of our Oracle VM Servers are either running OR powered off. Any machine lost in space such asOracle VM Manager: Restoring Backup
Execute the following steps to restore a backup of Oracle VM Manager Log in to the VM Manager Server as root. Save or copy Oracle VM Manager resources into the following directories VM images in OVS running_pool VM templates in OVS seed_pool and ISO files in OVS iso_pool. Restore backup by initiating the following commands cd
