Friday Spotlight: Oracle VM 3.3 and Oracle Virtual Networking

Happy Friday! In this week's Spotlight, we are talking about Oracle VM 3.3 with Oracle Virtual Networking. The topic is contributed by Daniel Ritzman, Principal Best Practices Consultant from Oracle VM product management and Satinder Nijjar, Principal Product Manager from Oracle Virtual Networking product management. 

Oracle Virtual Networking (OVN) virtualizes the data center infrastructure and enables connections from any virtual machine (VM) or server to other VMs, servers, network resources, and storage devices. With Oracle VM 3.3, the OVN kernel drivers are included with the Oracle VM Server. It's now much easier to take advantage of OVN Software Defined Network (SDN) capability in your Oracle VM environment.

The following steps cover some simple Oracle VM Server configuration, Fabric Manager Configuration and Oracle VM configuration needed to provision virtual network interface cards (vNICs) onto Oracle VM Server and then, from within Oracle VM Manager, provision the vNICs for various things that Oracle VM requires.

1. First we will need to install the user level OVN package on each of the Oracle VM Server's in the server pools. The orclovn-user-6.0.r7494-1.el6.x86_64.rpm package is available from both Oracle public-yum and Oracle Unbrealkable Linux Network (ULN).

2. After installing the RPM, run the following commands to enable and verify the xsigo service is configured to start upon boot:

# chkconfig xsigo on  
# chkconfig --list | grep xsigo
  xsigo 0:off 1:off 2:on 3:on 4:on 5:on 6:off
# reboot

We'll assume Fabric Manager has been installed on an Oracle Linux host and you have discovered the fabric interconnects. Also, that the network cloud for the Virtual Machine network has been configured defining the connections to your data center network. (You can review the following OTN articles to review these steps)

3. Next bring up fabric manager and verify that the Oracle VM servers show up in the Physical Servers table of Fabric Manager (Discovery of the servers on the managed fabric is automatic).

a) Launch your browser https://[Fabric Manager Host]:8443/xms

b) Provide network admin credentials

c) Navigate to Server Resource Manager->Physical Servers

You now see your Oracle VM Servers for you server pool displayed in the table.

4. Verify the Private Virtual Interconnect clouds to use, or create new ones for our VM's to use. Navigate to Network Cloud Manager->PVI Clouds. If they exist, verify they have been created and have state up/up. If they have not been created, create one for Live Migration.

a) Select the plus icon above the PVI Clouds table.

b) Provide a name for your live migration network cloud and select the MTU for the cloud

c) Select the SDN cloud where your PVI cloud should be created.

d) Select Submit

Note: When creating a PVI Cloud use the Oracle OVN which corresponds to the fabric on which your servers are wired. If multiple fabrics have been discovered, there may be more than one.

5. Next, create two PVI vNICs on one of the Oracle VM Servers in the server pool. (Live Migration, VM network)

Navigate back to Resource Manager->Physical Servers

a) From the Physical Server Summary, select the server that you would like to configure
b) Select the vNICs tab
c) Select the add icon (plus sign)
d) Provide the name for the vNIC and select the PVI cloud you created in the previous step for live migration
e) Click Submit

Repeat this process for the Virtual Machine network on the same Server.

6. Now that this server is configured with both PVI vNICs you can repeat the above process for the remaining Oracle VM Servers. Alternatively you can create a Template from the first server and apply it to the others.

7. In the Oracle VM UI you can create the networks on the Oracle VM Servers and assign them to their corresponding network Channels (Live Migration and Virtual Machine). The PVI vNICS created in the preceding procedure now show up as any other Ethernet interface. The steps for creating networks in OVM work exactly the same.

NOTE: A server rediscovery would be required to see the new interfaces unless it has rebooted since adding the vNIC’s in Fabric Manager

a) In the Networking tab select Networks and select the add icon (plus sign) to create a new OVM network.

b) Select "Create a network with bonds/ports only and press Next

c) Provide a name and optional description; Check the Live Migrate Network Channel and press Next

d) Select the Oracle VM Servers which you have configured the SDN networks from the Available Servers and press Next

e) Select the Ethernet port you defined for Live Migration and select Next

f) Configure the IP information and Mask for the interface and select Finish

Repeat the above steps for the VM network using the vlan for the VM network.

The configuration steps used above show a simple example of Oracle Virtual Networking can be integrated in your Oracle VM environment. For production environments requiring higher availability, additional HA vNICs would also be provisioned and configured (bonded) on the servers. Additionally QoS can be defined and networks and individual vNIC's can be assigned to ensure networking performance.

Friday Spotlight: Oracle Secure Global Desktop and amitego VISULOX

Happy Friday!

Our spotlight this week is a screencast about a fantastic solution that takes the security model of Oracle Secure Global Desktop and adds even more features.

If you work in environments where you need to have a video record of users' interactions with applications, or need to ensure that two users can remotely work on the same session (a worker entering data in a form from one workstation and a manager typing an authorization code from another, for example), amitego VISULOX can do this and a lot more. It's built on top of Oracle Secure Global Desktop, so you get all of the great features there, plus additional unique security related features provided by VISULOX.

Technology Preview of OpenStack Icehouse with Oracle Linux and Oracle VM - Now Available

On May we announced the technology preview of the OpenStack Havana release with Oracle Linux and Oracle VM, today we are releasing the technology preview of the Icehouse release. This release is a fast and easy way to deploy OpenStack giving customers an excellent starting point to deploy Icehouse and test it in their environment. We made sure that the deployment process remains the same as it was for Havana using few simple steps so anyone ,even with no prior experience with OpenStack, can install and try it out. The Icehouse release is an important step in the process of making OpenStack a first class enterprise solution, it continues the strong maturity curve of OpenStack and introduces more plug-ins , more bug fixes and around 350 new features.

Oracle Distribution of OpenStack for Linux will become part of Oracle Linux and Oracle VM premier support subscriptions at no additional cost. Like Oracle Linux and Oracle VM customers can use it for free or, shall they choose to, purchase support from Oracle and receive a complete production support for their deployment. As we stated previously, Oracle will support deployment of Oracle Linux and Oracle VM with any distribution of OpenStack the customer chooses and we will continue working with third party vendors to assure that we can integrate with their solution.

Please join us at Oracle OpenWorld on September 28th where we will have a special focus on OpenStack. At Oracle OpenWorld customers will have a chance to hear more about Oracle’s OpenStack strategy and products as well as see live demos and try them in the hands on labs.

Some technical details about the Icehouse tech preview release:

The download instructions are available here and the getting started guide is available here, for convenience we outline the few additional steps needed to complete the deployment

When deploying an Icehouse compute node with Oracle VM users have to perform two additional steps as part of their post-install steps. The two additional steps include setting the following parameters:

openstack-config --set /etc/nova/nova.conf libvirt cpu_mode none
openstack-config --set /etc/nova/nova.conf libvirt virt_type xen

When deploying an Icehouse compute node with Oracle Linux the two additional steps include setting the following parameters:

openstack-config --set /etc/nova/nova.conf libvirt virt_type kvm
openstack-config --set /etc/nova/nova.conf libvirt cpu_mode none

In both cases the operation needs to completed by restarting the nova-compute service:

service openstack-nova-compute restart
