Hightlights from Oracle OpenWorld 2014

At Oracle OpenWorld 2014, Renée J. James, President of Intel Corporation, shared her keynote on, "The Future of the Data Center in a Software-Defined World". She talked about Intel's Next Generation Firewall (NGFW) for Oracle VM.

Intel's Next Generation Firewall for Oracle VM

During the keynote, Steve Grobman, Intel Fellow and CTO of Intel Security Platforms showed the NGFW demo with Oracle VM Manager:

Steve explained how NGFW is going to address the security threat. Here's the value of the joint solution from Intel and Oracle.

  • Scalable and fast deployment of the virtual firewall instances powered by Oracle VM Templates

  • And better datacenter protection.

Oracle VM Manager 3.3 - Improvements on Virtual Machine Console Access

Oracle VM 3.3 introduces the new virtual machine console access which uses JavaScript and HTML5 features. There is no longer any requirement to install or run software locally on the client computer. This change reduces complexity and provides a more reliable console tool.

VNC access to a virtual machine:

Serial console access to a virtual machine:

To use the new virtual machine console access feature, ovmcore-console package needs to be installed on the server running Oracle VM Manager 3.3 in order to gain VNC and serial console access to virtual machines. We just released an updated version of ovmcore-console package (ovmcore-console-1.0-41) to ULN and public-yum.

Download the package from public-yum:

The package is also available at the ULN channels:

  • ol6_x86_64_addons
  • el5_x86_64_addons

The new package has integrated a few bug fixes:

  • Bug 18089107 - Fixes the issue of non-US keyboard mapping when accessing virtual machine console.
  • Bug 18969505 - Fixes the issue that the serial console fails to display long entries correctly.
  • Bug 18085387 - Fixes the issue that the cursor is not displayed in the serial console for SPARC guest.
  • Bug 19004079 - Fixes the issue that Control-C is mishandled in serial console.
For install/upgrade instructions, read the documentation: http://docs.oracle.com/cd/E50245_01/E50247/html/vmiug-manager-vncviewer-install.html

Oracle VM Manager 3.3 - Improvements on MAC Address Allocation


We announced Oracle VM 3.3 earlier today. Here I'd expand one feature enhancement which was delivered as part of the large networking implementation, and it brings significant benefit to simplify virtual NIC creation. Now with Oracle VM Manager 3.3, you can coordinate with other Oracle VM Manager 3.3 instances to avoid any potential MAC address collision.


  1. By default MAC addresses are automatically created using random numbers

    Oracle VM Manager chooses a MAC address using random numbers within the specified range when the user doesn't supply a specific MAC address. The default range has an OUI (Organizationally Unique Identifier), of 00:21:F6 and uses the remaining portion of 00:00:00 - FF:FF:FF from which to randomly choose a specific MAC address. This default range is used because the OUI prefix (00:21:f6) is officially registered to Oracle and should not conflict with any other vendors devices. However, that range can be changed.



  2. Have the ability to manually configure specific MAC addresses

    When a vnic is created, the user can specify any MAC address. The user supplied MAC address does not have to fall within the default range. The manager will validate that this MAC address is not already used by another vnic created in that manager.



  3. Allow to program your own OUI

    The manager allows the specification of an OUI other than the default and a range of addresses to use for the device specific portion of the MAC address.



  4. Range based allocation of MAC for each Oracle VM Manager instance to avoid collision

    The users need to explicitly set the range that they want to use. With coordination among Oracle VM Manager instances, you can set the range so that each Oracle VM Manager won't conflict with other Oracle VM Manager instances.

Use Local VNC Viewer to Access Guest VM Console

Here I'd like to explain how to configure the Java RAS proxy so that you can use your preferred local VNC client to access the guest VM console when using Oracle VM 3.2. For more details and the background, please consult Oracle VM 3.2 Installation and Upgrade Guide where it explains the VNC console used to connect virtual machines in x86-based server pools.



To configure which VNC viewer to use with the Options > Configuration menu item of the Java RAS proxy window, enter the path to the VNC client on the client desktop computer.


On a Windows desktop, for example,  specify the parameters $host and $port if the VNC client requires these parameters in a different format than the default host:port, then click OK.


If you don't have a local VNC viewer, be sure to get the latest TightVNC package from Oracle's public YUM repository to be installed on the server running Oracle VM Manager:



# rpm -ivh tightvnc-java-1.3.9-5.noarch.rpm
