VirtualBox 3.1 atnaujinimas

Pačioje gruodžio mėnesio pradžioje Sun Microsystems pristatė dar vieną eilinį Virtualbox atnaujinimą. Tiesa, galbūt jis ne toks eilinis dėl savo versijos – 3.1. Tai nauja šaka, kurioje jau pristatyta keletas naujų funkcijų, kurios paspartins VirtualBox veikimą kai kuriose sistemose. Tačiau iš esmės globalių naujų funkcijų nėra.
Šioje versijoje taip pat ištaisyta ganėtinai daug klaidų, kas padarys VirtualBox dar stabilesnę.

Naujos funkcijos

• Teleportacija (gyva migracija) – galimybė perkelti gyvą VM seansą iš vieno kompiuterio į kitą.
• VM statusai dabar gali būti atstatomi iš „snapshot’ų“ vietoje paskutiniojo, o nauji „snapshots“ gali būti padaryti iš kitų taip pat („branched snapshots“).
• 2D vaizdo akseleracija Windows’ams.
• Lankstesni laikmenų nustatymai: CD/DVD įrenginiai gali būti prijungti prie savarankiško IDE kontrolerio ir taip pat galima tai padaryti su daugiau nei vienu įrenginiu.
• Prijungto tinklo tipas gali būti keičiamas net VM esant įjungtam.
• Visiškai perrašytas USB palaikymas (vis dar eksperimentinis) OpenSolaris sistemoms.
• Stiprus paspartėjimas PAE ir AMD64 sistemoms (tik naudojant VT-x ir AMD-V, normalų „paging’ą“).
• Eksperimentinis EFI (Extensible Firmware Interface) palaikymas.
• Paravirtualių tinklo adapterių palaikymas (virtio-net).
