Sun xVm fail after upgrade ubuntu from 8.04 LTS to 8.10

After upgrade ubuntu from 8.04 LTS to 8.10, Sun xVM fail to start VM, dur to "VERR_VM_DRIVER_NOT_INSTALLED (rc=-1908)".

Have to run the command "/etc/init.d/vboxdrv setup" as root to re-setup the kernel module.

Upgrade ubuntu from 8.04 LTS to 8.10

By default Ubuntu 8.04 LTS will not offer a upgrade to 8.10. This is because the 8.04 LTS version is a long term support release and 8.10 is a regular release. Upgrades from 8.04 LTS to 8.10 are fully supported, of course, and easy to enable.

Just a few step, ubuntu homepage have details how to do it>>

Ubuntu® 8.10 Server Edition delivers significant new features to innovative user base

Ubuntu 8.10 Server Edition will be maintained for 18 months and adds significant enhancements in virtualisation, Java development and system management. This continues the project’s commitment to serve the needs of those users for whom innovation and performance are vital.

In tandem with the Ubuntu 8.04 Long Term Support (LTS) release, maintained for another four and a half years, Ubuntu offers users a real choice between the stability and longevity of the LTS releases and the opportunity to try the latest innovations of the Ubuntu 8.10 release. No other Linux or proprietary server OS supports this level of choice.

"Ubuntu 8.10 Server Edition is a terrific milestone that underlines the value in our twin track release strategy," said Jane Silber, COO of Canonical. "The server edition embraces cloud computing, virtualisation, mail server enhancements, Java development and deployment as well as a range of services to help system admininstrators and developers. Our six-monthly release cycle allows us to get these features in front of users faster continuing to make Ubuntu the best option for innovative organisations."

New to Ubuntu 8.10 Server Edition


Building on the Just Enough Operating System (JeOS) version launched last year, Ubuntu 8.10 ships with a Virtual Machine builder. It allows complete Virtual Machines to be built from the command line in less than five minutes. Developers and system administrators can script the creation of custom virtual images. Vm-builder provides a key component to a dynamic provisioning process for businesses using virtualisation environments.

JeOS has been merged into the Server CD and is now available as an option at installation time. Ubuntu 8.10 officially supports running as a paravirtualized guest on Xen hypervisors. KVM has also been updated to allow more flexible memory management. Administrators can reduce or increase the memory allocated to any virtual machine without having to reboot it.

Complete Java Stack

Apache Tomcat 6.0 and OpenJDK are now fully supported options that make Ubuntu a great choice for developing and deploying Java applications in production environments.

Enhanced Mail Server Capabilities

ClamAV and SpamAssassin are now available from the main repository providing a supported solution for spam detection and virus filtering for mail infrastructures built on Ubuntu Server.

Improved RAID Support

Ubuntu 8.10 provides support for SATA "software" RAID controllers via DMRaid. Booting from a degraded RAID array is now configurable by the system administrator.

Encrypted Private Directory

Administrators can now easily set-up an Ubuntu system to provide encrypted private directories which are automatically mounted when users login locally or via ssh. Sensitive data is kept secure even if the system is stolen.

Hardening the Packages

The tool chain used to compile Ubuntu has been updated to include even more security features such as glibc function call fortification. Bugs in applications are even harder to be turned into exploitable vulnerabilities.

Uncomplicated Firewall is Getting Even Simpler

The Uncomplicated Firewall makes it easier to manage a host firewall thanks to the addition of application profiles. Common services such as apache, bind9, cups, dovecot, openssh, postfix or samba declare which ports they use so that the administrator only enables a network service rather than a set of ports.

Landscape Client Bundled within Ubuntu

Landscape client provides a free reporting function at each login. Key information such as system statistics is added to the "message of the day" that is displayed at login (motd). Any type of metric can be gathered simply by writing plugins for Landscape client.

Landscape is Canonical's lightweight system management tool for Ubuntu systems that allows automated deployment and monitoring. Full activation of the client for landscape customers is now available within the installer.

Ubuntu 8.10 is coming soon

Ubuntu® 8.10 Desktop Edition enables mobile, flexible computing for a changing digital world

Ubuntu 8.10 Desktop Edition is designed for the pervasively connected digital lifestyle. With new 3G network support, users can move smoothly from wired and WiFi networks onto 3G cellphone networks while traveling. Ubuntu 8.10 is also built to be shared - users can start a quick "guest session" on the fly and let someone use their computer to surf the web or check email, while maintaining the security and integrity of their own data. And if that person really enjoys their brief session as an Ubuntu guest, they can put Ubuntu on any USB key and take it home to install on their own computer rather than having to burn a CD.

As a bonus, all Ubuntu 8.10 users will be able to enjoy programming from the BBC, with high quality streamed content available through the default media players in Ubuntu 8.10. Canonical has worked with the BBC to make sure that much of the material is available to users in all locations.

"Ubuntu 8.10 sees us lay the groundwork for a radically different, more mobile, desktop computing environment over the next two years," says Jane Silber, COO of Canonical and head of Online Services for Canonical. "Our rapid release cycle means we can deliver the elements to support this future faster, more fully realised, and more attractively packaged than the traditional OS vendors. Ubuntu 8.10 has many features that sign-post how Linux will provide the drive and innovation in desktop computing."

"Working with open source technologies like GNOME, Ubuntu 8.10 provides exciting new features for users like creating an always-on system that seamlessly connects wireless and cellular networks," said Stormy Peters, executive director at the GNOME Foundation. "Users no longer need to worry about finding a network - their computer is always connected. This is a great step for both mobile and desktop computing."


3G Support

For constant connectivity public WiFi has limitations. Improvements to the network manager in Ubuntu 8.10 makes it simple to detect and connect to 3G networks and manage connectivity. This connectivity is delivered through an inbuilt 3G modem, through 'dongle' support, through a mobile phone or through Bluetooth. It is a complex environment that Ubuntu 8.10 simplifies through a single interface and the auto-detection of many of the most popular devices.

Write Ubuntu to and Install from a USB Drive

Ubuntu has been made available to users as an image for CDs and DVDs to date. But CDs and DVDs are slower, less portable and less convenient than USB sticks. Now, a simple application in Ubuntu will allow users to write Ubuntu to a USB drive, even a modified version of Ubuntu with their data on it, so it can be carried everywhere to plug in and use on any machine.

Guest Sessions

In a world of 'always on' pervasive computing it is more likely that users lend their computers to colleagues or friends at conferences, cafes or at parties so they can check email, etc. Guest sessions allow users to lock down a session easily so a guest can use the full system without interference with programs or data.

BBC Content

Starting the media players within Ubuntu (Totem Movie Player and Rhythmbox) launches a menu of selected content from the broadcaster that is free to air. This is a mixture of video, radio and podcasts and available in high quality, much of it playable using non-proprietary codecs. Content is constantly updated via the corporation's stream and will vary dependent on location, though some content will be available for every user.

Latest Gnome 2.24 Desktop Environment*

The GNOME desktop environment project releases its latest version which is incorporated into Ubuntu 8.10. New features include a new instant messaging client, a built-in time tracker, , improved file management and toolbars plus better support for multiple monitor use with the ability to set screen resolution by monitor.

Ubuntu 8.10 is coming soon

How to install Sun Java Development Kit (JDK) & Java Runtime Environment (JRE) on Ubuntu Linux

- Run the following command in Terminal:

$ sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk

- Set the Sun Java as the default Java:

$ sudo update-java-alternatives -s java-6-sun

- Make the Sun JVM as the first searchable JVM

used and text editor to edit the file /etc/jvm. Make sure /usr/lib/jvm/java-6-sun is the first in the jvm list.

# This file defines the default system JVM search order. Each
# JVM should list their JAVA_HOME compatible directory in this file.
# The default system JVM is the first one available from top to
# bottom.



used and text editor to edit the file $HOME/.bash_profile

Append the line:

export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$PATH:$JAVA_HOME/bin

- Now you can clarify you java version:

$ java -version

java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)

- That's.
