I may be the last one to write about it, but yes, Oracle VM VirtualBox 4.0 had been released. Although I was trying to get the latest version downloaded from the Virtual Box website, but I was unsuccessful. For the details about the new features added with this version, click here. I had been using VirtualBox since a while, although for sometimes I had used VMLite as well. Most of my test VMs at home are based on VirtualBox. Two things you may want to consider before running the upgrade package of VirtualBox 4.0:
1. Take a backup of your existing Virtual Machines. Although my test VMs are running using the evaluation edition of the software, I still prefer to take a backup of my Virtual Machines. You may aware of that VirtualBox 4.0 is a major release, and you may want to rollback in case of failure of the upgrade.
2. It is also necessary to upgrade the Virtual Machine Guest Additions, after upgrading the base product.
Without further delay, I am going to start the upgrade process. Double click on the setup file to start the installation process.
Once we have installed the VirtualBox 4.0, then we are going to install the Oracle_VM_VirtualBox_Extension_Pack-4.0.0-69151.vbox-extpack. This extension pack will provide further enhancements which includes USB Host Controller, Virtual RDP, etc. As we have already installed VirtualBox 4.0 Extension pack, its time to update the VirtualBox Guest Additions. Start the virtual machine and log into the virtual machine with an administrative account. Click on Install the Guest Addition to start the installation of guest addition.
Hope, this will be helpful for you, 🙂
