Consider a Windows 7 host where the VirtualBox guest is configured to use Bridged Adapter.

An exception is raised when starting this guest machine:

Failed to open/create the internal network HostInterfaceNetworking (VERR_SUPDRV_COMPONENT_NOT_FOUND)

Result Code: E_FAIL (0x80004005)

What resolution is there to this problem for Bridged Adapters in VirtualBox?

The solutions attempted:

• changed Adapter Type to all available choices. No changes.
• uninstall VirtualBox, reboot host, re-install VirtualBox. No change in behaviour.
• edited the machine's .xml file, wiping out all <Network> <Adapter> nodes. Had VirtualBox re-create those nodes. No change.

Host Details

• Oracle VirtualBox 3.2.4 (release 62467)
• Windows 7 x86
