Oracle(http://www.virtualbox.org)에서 제작한 VirtualBox는 무료로 제공되는 가상화 프로그램입니다. 2월 12일 릴리즈되었습니다.

 

VirtualBox 프로그램은 VMware Workstation과 거의 비슷한 인터페이스를 보여주며 한글 지원으로 사용이 편리합니다.

 

개선사항

 

- VMM: refined measurement of TSC frequency on the host, improves timekeeping for guests
- VMM: decreased CPU load resulting from guest MMIO writes to the virtual APIC
- VMM: fixed interception of debug exceptions, observed while using the dbx debugger on Solaris guests (VT-x only)
- GUI: 3D overlay window positioning code improved, fixed potential misplacement of 3D accelerated guest graphics content
- GUI: fixed accident SSL authentication failures during update check on Windows hosts
- GUI: never send the "ACPI power" keyboard scancode to the guest, we have the ACPI power button for that
- GUI: was unable to properly restore seamless mode VM from snapshot/saved-state under some circumstances
