The 4.2 branch of VirtualBox was known to have a bug with real mode which prevented to run Plan 9 (and QNX) successfully. This bug was fixed in VirtualBox 4.2.14, as you can see in the changelog. https://www.virtualbox.org/wiki/Changelog > BIOS: don't use the ENTER / LEAVE instructions in the BIOS > as these don't work in the real mode as set up by certain > guests (e.g. Plan 9 and QNX 4) If you want to run Plan 9 on VirtualBox, you have to use either the 4.1 branch (for example 4.1.26) or 4.2.14 and later. -- David du Colombier
