About VirtualBox in VDI 3.1
VDI 3.1 supports only specific Sun VirtualBox versions. For accurate and up-to-date information about version support, refer to the VDI 3.1 Release Notes. VirtualBox for VDI 3.1 provides the following new VirtualBox desktop provider features.
Desktop Suspend and Resume
VDI 3.1 offers the ability to suspend and resume desktops across VirtualBox hosts. This functionality supports the following new features:
- Suspended Pool Power State
Desktops in a pool will be booted and then suspended, ready for fast user access without the resource overhead of keeping your desktops running.
- Host Migration
Desktops can be cold migrated from one VirtualBox host to another. This functionality will suspend all desktops on a specified host and resume them on other available hosts in the Desktop Provider with only a minimal outage. For more information about the Host Migration feature, see the About Maintenance Mode page.
- Suspend Host
Suspend all desktops on a specified VirtualBox host, enabling it to be maintained or upgraded easily. After maintenance is complete, simply re-enable the VirtualBox host and all desktops will be resumed to their original state.
 | To use suspend and resume reliably, all VirtualBox hosts in a desktop provider should contain identical CPU models. |
Non-Windows Desktop Recycling
Recycling is now supported for non-Windows desktops including OpenSolaris, Ubuntu, and SUSE Linux Enterprise Desktop.
Desktop Import Improvements
In VDI 3.0, virtual machine templates had to be moved to the VDI Core host in order to be imported to and managed by the VDI Manager. In VDI 3.1, you have the choice of importing templates from the VDI Core host or the Sun VirtualBox host.
