But that’s not all: VirtualBox 4.0 beta also comes with a redesigned user interface, settings/disk file layout for VM portability, support for more than 1.5/2 GB guest RAM on 32-bit hosts, support for the Intel ICH9 chipset, support for limiting a VM’s CPU time and IO bandwidth, asynchronous I/O for iSCSI, VMDK, VHD and Parallels images, support for resizing VDI and VHD images and more.
Install VirtualBox 4.0 beta in Ubuntu
Before installing VirtualBox 4.0, please remember it’s still in beta so expect to find bugs (so use it at your own risk)!
sudo apt-get remove virtualbox*
2. In Ubuntu 32bit only, you’ll also have to install libstdc++5:
sudo apt-get install libstdc++5
4. Download the VirtualBox extensions pack. Then, once you’ve made sure you’ve closed all open VirtualBox windows, simply double click the “Oracle_VM_VirtualBox_Extension_Pack-4.0.0_BETA1-68572.vbox-extpack” file you’ve just downloaded – this should install the VirtualBox extensions pack and open VirtualBox.
