VirtualBox 3.2.0 Final

Leave a reply

VirtualBox 3.2.0 Final es un programa de virtualización . VirtualBox 3.2.0 está disponible para su ejecución en sistemas Windows y Linux de 32-bits (aunque hay también una versión beta para MacOS X) y es capaz de virtualizar Windows, Linux (versión del núcleo 2.x), OS/2 Warp, OpenBSD y FreeBSD.

Comparado con otros programas de virtualización como VMware o Virtual PC, VirtualBox carece de algunas funcionalidades, pero a cambio aporta otras como: ejecución remota de máquinas virtuales utilizando Remote Desktop Protocol (RDP), soporte para iSCSI y soporte para USB con dispositivos remotos sobre RDP.

Lista de Cambios en VirtualBox 3.2.0 (released 2010-05-18)

This version is a major update. The following major new features were added:

  • Following the acquisition of Sun Microsystems by Oracle Corporation, the product is now called Oracle VM VirtualBox and all references were changed without impacting compatibility
  • Experimental support for Mac OS X guests (see the manual for more information)
  • Memory ballooning to dynamically in- or decrease the amount of RAM used by a VM (64-bit hosts only) (see the manual for more information)
  • Page Fusion automatically de-duplicates RAM when running similar VMs thereby increasing capacity. Currently supported for Windows guests on 64-bit hosts (see the manual for more information)
  • CPU hot-plugging for Linux (hot-add and hot-remove) and certain Windows guests (hot-add only) (see the manual for more information)
  • New Hypervisor features: with both VT-x/AMD-V on 64-bit hosts, using large pages can improve performance (see the manual for more information); also, on VT-x, unrestricted guest execution is now supported (if nested paging is enabled with VT-x, real mode and protected mode without paging code runs faster, which mainly speeds up guest OS booting)
  • Support for deleting snapshots while the VM is running
  • Support for multi-monitor guest setups in the GUI for Windows guests (see the manual for more information)
  • USB tablet/keyboard emulation for improved user experience if no Guest Additions are available (see the manual for more information).
  • LsiLogic SAS controller emulation (see the manual for more information)
  • RDP video acceleration (see the manual for more information)
  • NAT engine configuration via API and VBoxManage
  • Use of host I/O cache is now configurable (see the manual for more information)
  • Guest Additions: added support for executing guest applications from the host system (replaces the automatic system presimparation feature; see the manual for more information)
  • OVF: enhanced OVF support with custom namespace to preserve settings that are not part of the base OVF standard

In addition, the following items were fixed and/or added:

  • VMM: fixed Windows 2000 guest crash when configured with a large amount of RAM (bug #5800)
  • Linux/Solaris guests: PAM module for automatic logons added
  • GUI: guess the OS type from the OS name when creating a new VM
  • GUI: added VM setting for passing the time in UTC instead of passing the local host time to the guest (bug #1310)
  • GUI: fixed seamless mode on secondary monitors (bugs #1322 and #1669)
  • GUI: offer to download the user manual in the OSE version (bug #6442)
  • Main: allow to start a VM even if a virtual DVD or floppy medium is not accessible
  • Settings: be more robust when saving the XML settings files
  • Mac OS X: rewrite of the CoreAudio driver and added support for audio input (bug #5869)
  • Mac OS X: external VRDP authentication module support (bug #3106)
  • Mac OS X: Moved the realtime dock preview settings to the VM settings (no global option anymore). Use the dock menu to configure it.
  • Mac OS X: added the VM menu to the dock menu
  • 3D support: fixed corrupted surface rendering (bug #5695)
  • 3D support: fixed VM crashes when using ARB_IMAGING (bug #6014)
  • 3D support: fixed assertion when guest applications uses several windows with single OpenGL context (bug #4598)
  • 3D support: added GL_ARB_pixel_buffer_object support
  • 3D support: added OpenGL 2.1 support
  • 3D support: fixed Final frame of Compiz animation not updated to the screen (Mac OS X only) (bug #4653)
  • 3D support: fixed blank screen after loading snapshot of VM with enabled Compiz
  • Added support for virtual high precision event timer (HPET)
  • OVF: fixed mapping between two IDE channels in OVF and the one IDE controller in VirtualBox
  • OVF: fix VMDK format string identifiers and sort XML elements from rasd: namespace alphabetically as prescribed by standard
  • VBoxShell: interactive Python shell extended to be fully functional TUI for VirtualBox
  • Linux Additions: support Fedora 13 (bug #6370)
  • VBoxManage: fixed overly strict checks when creating a raw partition VMDK (bugs #688, #4438)
