VirtualBox 4.3.6

Met VirtualBox kun je binnen een besturingssysteem een ander besturingssysteem (os) virtueel draaien. Handig om Linux vanuit Windows uit te proberen bijvoorbeeld.

VirtualBox 4.3.6 is gisteren uitgebracht. Dit is de derde onderhoudsupdate voor versie 4.3, waarin diverse crashes, regressies en fouten gerepareerd. Onder andere worden niet automatisch 64-bit gastbesturingssystemen ingeschakeld op 64-bit hosts als VT-x/AMD-V niet beschikbaar is. Verdere details kun je hieronder nalezen.

VirtualBox is beschikbaar voor Windows, Mac OS X en Linux. Het is aan te raden om ook het Extension Pack te installeren, zodat je onder andere ondersteuning voor USB hebt.

Changelog:
This is a maintenance release. The following items were fixed and/or added:

VMM: fixed a Guru Meditation VINF_EM_TRIPLE_FAULT caused by VMCB caching with nested paging on certain AMD CPUs (bug #12451)
VMM: fixed a Guru Meditation VERR_VMX_UNEXPECTED_INTERRUPTION_EXIT_TYPE while intercepting debug exceptions (VT-x only; bug #12410)
VMM: fixed a Guru Meditation VERR_SVM_UNEXPECTED_EXIT while intercepting debug register accesses (AMD-V only; bug #12481)
VMM: fixed a VERR_SSM_STRUCTURE_MAGIC error when trying to load a saved state made with VBox 4.3.4 when VT-x/AMD-V is disabled. Unfortunately, VBox 4.3.4 produced broken saved states for this configuration so you have to discard these states (bug #12414)
VMM: added a few more MSRs to the whitelist required by certain guests (bug #12245)

Network: allow to start more than 5 PCNet instances (bug #12426)
E1000: if the cable was disconnected before the guest initialized the device, the link status was not properly set to 'down' after the initialization completed despite the fact that there was no connection
