(Doc ID 1524521.1)

Last updated on APRIL 30, 2013

Applies to:

Oracle VM VirtualBox - Version 4.0 to 4.2 [Release 4.0]
Information in this document applies to any platform.

Symptoms

While using a Japanese 106 keyboard, with a Virtual Machine hosted with Oracle VM VirtualBox software, one would notice that special keys such as "]" are not able to be type in, i.e. they do not appear.

Changes

Effective from Oracle VM VirtualBox version 4.0, a change was introduced where VirtualBox switched to using the X11 XKB keyboard extension for detecting the mapping to use between the host keyboard keys and the emulated guest keyboard.
