Oracle VirtualBox
대표적인 가상화(Virtualization) 솔루션의 하나이면서 오픈 소스 소프트웨어인 VirtualBox(버추얼박스)  3.2.6 버전이 두 차례의 베타 테스크를 거쳐 6월 25일자로 나왔다. 3.2.0 버전부터는 Mac OS X을 게스트 운영 체제로도 지원("VirtualBox에 Mac OS X 설치하기", 2010. 5. 5.)하기 때문에 과거보다 더 많은 주목을 받고 있다.

  • VMM: allow 64-bit SMP guests on 32-bit hosts (VT-x and AMD-V only; does not apply to Mac OS X, which already supports it)
  • VMM: fixed Guru mediation if guests with more than 2GB are booted with VT-x/AMD-V disabled
  • VMM: fixed TR limit trashing (VT-x and 64-bit host only)
  • Page Fusion: several bug fixes for SMP guests
  • Teleportation: several fixes and improvements
  • Mac OS X server guests: compatibility fix

  • iSCSI: fixed authentication
  • Host-only/bridged networking: fixed excessive host kernel warnings under certain circumstances (Linux hosts only; 3.2.0 regression)

  • E1000: disconnect cable was not properly handled if the NIC was not yet initialized by the guest
  • OVF: export performance optimization
