VirtualBox 4.3.8


VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

Some of the features of VirtualBox are:

  • Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
  • Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.

I love VirtualBox and have no issues at all running XP in it. I'd try VMware but there isn't a portable version that I know of. There is for VirtualBox and I absolutely must have portable software except for a few. Flash, Java, .NET 2.0, Wuala and maybe a couple more

Wish they would hurry up and make drag and drop work on the Windows version. It works in the Linux version.

I thought I was the only one thinking it does not work as good as VMWare Player for Windows XP (now ancient dinosaur OS).. Jokes apart. It really does not make using Windows XP experience fully updated quite hectic free.

BTW Changelog:
VMM: more work on improving the emulation of certain MSR registers (e.g. bugs #12224, #12544)
VMM: fixed a VERR_INVALID_RPL Guru Meditation when booting certain guests (bug #11350)
VMM: experimental support for SSE 4.1 / SSE 4.2 passthrough, see the manual for more information how to enable it (bug #8651)
VMM: fix for recent Linux kernels with software virtualization
GUI: experimental HID LEDs synchronization for Windows hosts, see the manual for more information
GUI: warn the user if the Oracle Extension Pack is not installed and the user tries to activate the remote display feature (bug #9104)
GUI: make sure that a minimized guest (using mini toolbar in fullscreen/seamless mode) keeps the minimized state (bug #12199)
GUI: popup banner's "do not show this message again" check-box replaced with corresponding button
GUI: network adapter cables can now be connected/disconnected directly through the running virtual machine Devices / Network menu a Network status-bar indicator
GUI: the new VM wizard now proposes 64-bit guests on 64-bit hosts by default; better distinction between 32-bit OS types 64-bit OS types (bug #12533)
GUI: better error message if appliance import fails (bug #12657)
GUI: allow to set host-combination to 'None' using the Global settings / Input page (bug #12730)
GUI: don't switch the guest to a black screen during online snapshot merge (4.3 regression)
VBoxManage: when exporting an appliance, support the suppression of MAC addresses, which means they will be always recreated on import, avoiding duplicate MAC addresses for VMs which are imported several times
AHCI: fixed a VM hang during suspend under certain circumstances
AHCI: fixed a VM hang during online snapshot merge under certain circumstances
AHCI: fixed a bug which resulted in Windows XP guest hangs if a SATA CDROM is attached (bug #12417)
AHCI: fixed a Guru Meditation under certain conditions
AHCI: ejecting a CD/DVD medium failed under certain conditions
AHCI: disk hotplugging fixes
NAT: transparent handling of host sleep/resume and network configuration changes if the dnsproxy is enabled or if the hostresolver is used (bug #12441)
NAT: fixed crash and misbehaviour under some circumstances with ICMP packets having TTL=1
NAT Network: fixed IPv6 reassembly
NAT Network: ping proxy implemented
OVF: fixed reading of the OVF 0.9 section element (4.3 regression; bug #12345)
OVF: several fixes
3D: several fixes, multiscreen fixes (e.g. bug #9124)
3D: include 3D content in captured videos (bug #12666)
3D: include 3D content in captured screenshot (bug #11758)
VGA: proper handling of legacy graphics modes if the Guest Additions are active (bug #6649)
USB: fixed crash during isochronous transfer under rare circumstances
BIOS: better disk geometry handling of SCSI drives
API: fix crashes in Java API clients using the XPCOM binding, happened with output parameters only (bug #11232)
VBoxSVC: documented the handling of host power management events (see the manual for more information) and added an extradata item for configuring the handling of the battery-low event (bug #9925)
VBoxSVC: fixed a bug which could trigger a crash if a VM snapshot was restored the second time and the VM has associated bandwidth groups (bug #12569)
VBoxSVC: properly detect ifconfig if located in /bin (bug #12713)
Shared Folders: fixed a failure to restore transient shared folders when starting a VM from a saved state (bug #12578)
Mac OS X hosts: fixed issue when the application icon was frozen in the dock if the bridging interface was not connected to a network (bug #12241)
Linux hosts: also consider the physical package ID when determining the number of physical CPU cores
Linux hosts / guests: don't warn in kernel log if memory allocation fails (bug #11171)
Solaris hosts: fixed the autostart SMF script (bug #11720)
Windows hosts: fixes for non-ANSI code page user names and similar environment contents (bug #12596)
Windows hosts / guests: fixed setting and using a guest user's process environment variables (relevant for Guest Control)
Windows Additions: fixed handle leaks in VBoxTray (bug #12563)
Windows Additions: fixed a crash while detecting active guest users
Windows Additions: fixed restoring backed up D3D files on XPDM -> WDDM upgrade

Linux Additions: fixed CPU hot-remove on newer Linux kernels
Linux / Solaris Additions: don't automount a shared folder which is already mounted
X11 Additions: support X.Org Server 1.15 (bug #12623)

If you think Windows XP is bad, try DOS and Windows 95 to ME.
I don't get how VMWare Player can do Windows ME @ 1080p yet Virtual Box these days requires either a buggy or proprietary (30 day trial) 3rd party driver just to get beyond 16 colours @ VESA and forced ACPI support during installation to avoid consuming all allocated IO resources.

I agree, GPU driver for Windows XP is also pathetic, giving two much resources for mere XP and still it crawls, my old Pentium 4 single core with half the resources was running XP much faster than this 2 GB, Quad Core Virtual Machine.

XP is I/O intensive as it tries to load everything at once on a mechanical drive which as we know can only load one thing at a t ime with the arm spinning back and forth. CPU is sitting there idle during boot mostly.

Modern drivers written in .NET SDK such as AMD's catalyst can slow the system down 10x when loading compared to a 2003 era ati rage pro driver .dll that is 1/30th the size. It is one of the arguments that XP loyalists use on why not to upgrade to WIndows 7. 40 gigs to load a freaking OS?! etc

Services are more event driven in Windows 7 and with an SSD are a good 300x faster access latencies. This helps as things do not try to overload the disk during startup unlike XP.

XP is dirt fast on an SSD and it makes those with Pentium IV's jaws drop to see it in action.
