Oracle VM Virtualbox 3.2.12

Après presque deux mois d'intense recherche, voici qu'une nouvelle version du virtualisateur de systèmes d'exploitation d'Oracle fait son arrivée. Avec cette version 3.2.12 qui se focalise sur l’amélioration de performances notamment afin de prévenir les risques de ralentissements pour les processeurs possédants les instructions de virtualisation matérielles en mettant en oeuvre la gestion d'une nouvelle instruction évitant ce désagrément.

Sur Linux, c'est la compilation en dure qui se fera pour le driver graphique vboxvideo si DKMS n'est pas installé. Le reste des changements est disponible ci-dessous :

• VMM: fixed rare host crash when running 64-bit guests on 32-bit hosts (bug #7577)
• VMM: fixed host reboots under rare circumstances due to NMIs triggered by active performance counters (Linux hosts in non-VT-x/AMD-V mode only; bug #4529)
• VMM: fixed out of memory guru meditation for large memory guests (bug #7586)
• VMM: fixed a guru meditation related to large pages
• VMM: use new VT-x feature to keep the guest from hogging the CPU
• Snapshots: implemented deleting the last remaining snapshot while the VM is running
• GUI: perform the checks for exceeding the size limit of the host file system and for broken asynchronous I/O on older Linux kernels with ext4 / xfs file systems not only when starting the VM from scratch but also when starting from a saved state
• NAT: fixed memory leak (3.2.0 regression; bugs #6918, #7353)
• Networking: fixed VM reset handling in e1000
• VRDP: fixed rare crash in multimonitor configuration

• Graphics: Horizontal resolutions are no longer restricted to a multiple of 8 pixels (bug #2047; requires Guest Additions update).
• USB: fixed a crash with older Linux kernels and non-ASCII characters in device strings (Linux hosts only; bug #6983, #7158, #7733; version 3.2.8 contained an incomplete fix)
• USB: fixed a crash under rare circumstances (bug #7409; Windows hosts only)
• iSCSI: respond to NOP-In requests from the target immediately to avoid being disconnected if the guest is idle
• 3D support: fixed a crash under certain circumstances (bug #7659)
• 3D support: fixed crashes for GLUT based apps (bug #6848 )

• 2D Video acceleration: fixed potential deadlock when saving the VM state (bug #4124)
• Windows hosts: another fix for BSODs under certain circumstances in VBoxNetFlt.sys (bug #7601)
• Solaris hosts: fixed host USB DVD drive detection
• Mac OS X hosts: fixed swapped keys for certain ISO keyboard types (bug #2996)
• Linux hosts: added link state handling for TAP devices needed for proper operation with bridged networking on kernels 2.6.36 and above (bug #7649)
• Linux hosts/guests: Linux 2.6.37 fixes
• Linux Additions: properly compile the vboxvideo module if DKMS is not installed (bug #7572)
• Linux Additions: fixed a memory leak when accessing non-existing files on a Shared Folders (bug #7705)
