Oracle VM VirtualBox 6.1.0


Oracle VM VirtualBoxOracle VirtualBox是由德国InnoTek软件公司出品的虚拟机软件,现在则由甲骨文公司进行开发,是甲骨文公司xVM虚拟化平台技术的一部份。它提供用户在32位或64位的Windows、Solaris及Linux 操作系统上虚拟其它x86的操作系统。用户可以在VirtualBox上安装并且运行Solaris、Windows、DOS、Linux、OS/2 Warp、OpenBSD及FreeBSD等系统作为客户端操作系统。

与同性质的VMware及Virtual PC比较下,VirtualBox独到之处包括远程桌面协议(RDP)、iSCSI及USB的支持,VirtualBox在客户机操作系统上已可以支持USB 2.0的硬件设备,不过要安装 virtualbox extension pack.

VirtualBox 6.1.0 (released December 10 2019)

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

Implemented support for importing a virtual machine from Oracle Cloud Infrastructure
Extended support for exporting a virtual machine to Oracle Cloud Infrastructure, allowing the creation of multiple virtual machines without re-uploading. Also added option to export a VM to the cloud using the more efficient variant “paravirtialized”, and to specify free-form tags for cloud images
Virtualization core: Support for nested hardware-virtualization on Intel CPUs (starting with 5th generation Core i, codename Broadwell), so far tested only with guest running VirtualBox
Graphics: New style 3D support (with VBoxSVGA and VMSVGA) remains, old style 3D support (with VBoxVGA) has been completely removed
Shared Clipboard: Implemented experimental support for file transfers (Windows hosts/guests only at the moment). Needs to be enabled via VBoxManage (disabled by default). In addition, the following items were fixed and/or added:
Virtualization core: Drop recompiler, i.e. running VMs now needs a CPU supporting hardware virtualization
Runtime: Works now on hosts with many CPUs (limit now 1024)
Appliance and Cloud Import: Add field for defining firmware type (not part of OVF spec and thus manual in the Appliance case, for OCI it is automatically taken from the instance information)
GUI: Improved the VISO creation and file manager dialogs
GUI: Virtual machine list of VirtualBox Manager was improved. Machine groups are now more obvious visually and VM search functionality has been improved. Global Tools element can now be pinned in place, to avoid scrolling it with rest of machine list
GUI: Virtual machine details pane is now extended with embedded editors for selected VM attributes, allowing user to edit them on-the-fly byi clicking corresponding hyper-links without opening VM settings dialog
GUI: Details pane provides more complete information
GUI: Internal medium enumeration routines were optimized to reduce the load and optimize the performance in cases when user have lots of media registered. Also, we again allowed to add existing media (and create new) via Virtual Media Manager
GUI: More consistent medium selection (both showing known images and allowing to select using the file picker)
GUI: VM storage settings page was adjusted a bit in usability regard. User is now allowed to change controller bus type and can move attachments between the controllers by using drag and drop
GUI: Storage and Network settings pages bug-fixes and usability optimization
GUI: Added a new soft (virtual) keyboard enabling arbitrary keyboard input to guests, including multimedia keys
GUI: Fixed crash in cloud related wizards when accessibility functionality was enabled
GUI: Show VM CPU load as part of status bar CPU indicator
GUI: Improved and extended the Session Information dialog
GUI: Fixed/improved mouse pointer scaling
GUI: Some issues related to mouse integration cursor scaling were addressed (bug #14366), more to go
GUI: Fix and unify geometry save/restore in various dialogs
GUI: Added the missing restriction options for disabling new functionality such as the VISO creator
GUI: Popup messages mouse click fix
Graphics: Remove 3D support for VBoxVGA (old one deprecated with 6.0)
Graphics: Additional texture format support on Windows host
Graphics: Improved fix for flickering on Windows host
Input: Added support for horizontal scrolling in the PS/2 mouse device using the IntelliMouse Explorer protocol. Note that this support is automatically used by Linux guests but not by Windows guests
vboximg-mount: Experimental support for direct read-only access to NTFS, FAT and ext2/3/4 filesystems inside a disk image without the need for support on the host
vboximg-mount: Now also available on Linux host
Storage: Experimental support for virtio-scsi, for both hard disks and optical drives (including boot support in BIOS)
Storage: For optical drive emulation fix empty host drive crash
USB: Improvements for EHCI controller implementation
USB: Filter can now specify port path, uniquely identifying a port in a system
NAT: Fix TFTP OACK response, send only if request has options
NAT Network: Use non-blocking sockets on Linux for accepted incoming connections (port forwarding)
PCnet-ISA: Added new network adapter type, currently CLI only
Audio: Allow changing the host audio backend while the VM is in saved state
ACPI: Report NVMe controller
VGA: Improve hardware and BIOS compatibility
VBoxSVGA/VMSVGA: Support YUV2 and related texture formats with hosts using OpenGL (macOS and Linux), which accelerates video playback when 3D is enabled by delegating the color space conversion to the host GPU
VBoxSVGA/VMSVGA: Several drawing fixes for the 3D case
VMSVGA 3D: Fixed OpenGL compressed textures
VBoxManage: More cloud functionality coverage, e.g. starting a cloud instance
VBoxManage: As part of the guest control feature support moving multiple source files/directories to a target directory
Guest Control/VBoxManage: Added support for specifying multiple sources when renaming guest files
VBoxManage: Show “unrestricted guest” and “nested HW virtualization” CPU features when listing the host information
API: Reduce the amount of leftovers from Move VM function
Shared Clipboard: Implemented experimental support for file transfers for Linux hosts on Windows guests (disabled by default)
SMBIOS: Store system UUID in little endian format which is the default for new VMs, while existing VMs stick to the old VirtualBox behavior of storing them in big endian format for backwards compatibility to avoid breaking the activation status of Windows VMs
VBoxSDL frontend: Fixed running on Windows hosts
macOS host: Fix VM crashes (most visible on macOS Catalina)
Linux host: Improve vboxweb systemd service dependency information
Linux host: Drop PCI passthrough, the current code is too incomplete (cannot handle PCIe devices at all), i.e. not useful enough
Linux host and guest: Support Linux 5.4 (bug #18945)
Linux host and guest: Force disabling of kernel module signing during build (user can do it afterwards)
Windows host: When possible, distinguish USB devices by port number; helps with accurate capturing of devices when multiple otherwise identical devices are connected
Windows Guest Additions: Many fixes for drawing problems in the driver for VBoxSVGA
Windows Guest Additions: Fixes for legacy VBoxVGA adapter, restore previously working cases
Windows Guest Additions: Restore VHWA functionality for VBoxSVGA
Windows guest: DXVA implementation for WDDM driver
Documentation: Updated supported host operating systems, added few new manual pages (more to come later)
EFI: Switch to newer firmware code base and add NVRAM support, should improve compatibility with OSes significantly
EFI: Added support for booting from APFS
EFI: Added support for non-standard SATA and NVMe boot device paths created by OS X
EFI: Modified updated EFI code base to support older OS X guests again

    […]   新出的Windows 7里面有一个XPM技术,即Windows XP模式,是为了安装一些老软件而特意增加的新功能。但是你想要开启XP模拟模式,首先你的CPU必须要支持虚拟技术(简称:VT),向我们这种穷人所使用的赛扬、奔腾等等肯定是不支持的。不过没关系,有了VirtualBox,也可以让你梦想成真。 […]
