Download virtualbox 64 bit for windows 7
VirtualBox doesn’t care what you use as long as you configure it properly. We can also use different versions of Linux within Linux or Windows within Windows. You could run Linux within Windows or the other way round. another operating system, and keep it completely separate from the one running the computer, as if the guest software is in a box, away from everything else. By creating a virtual machine, we can run guest software, i.e. So, instead of running many such physical computers that are only partially used, one can pack many virtual machines onto a few powerful hosts and balance the loads between them.VirtualBox is free virtualization software that allows us home users to play with multiple operating systems within our main computer. A lot of hardware resources as well as electricity is thereby wasted. Most of the time, computers today only use a fraction of their potential power and run with low average system loads. Virtualization can significantly reduce hardware and electricity costs. You can delete snapshots while a VM is running to reclaim disk space. Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time. after installing misbehaving software or infecting the guest with a virus), one can easily switch back to a previous snapshot and avoid the need of frequent backups and restores. This way, one can freely experiment with a computing environment. On top of that, with the use of another VirtualBox feature called “snapshots”, one can save a particular state of a virtual machine and revert back to that state, if necessary.
Once installed, a virtual machine and its virtual hard disks can be considered a “container” that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts. Installing and running a mail server becomes as easy as importing such an appliance into VirtualBox. With VirtualBox, such a complex setup (then often called an “appliance”) can be packed into a virtual machine.
For example, installing a complete mail server solution on a real machine can be a tedious task. Software vendors can use virtual machines to ship entire software configurations. Since you can configure what kinds of “virtual” hardware should be presented to each such operating system, you can install an old operating system such as DOS or OS/2 even if your real computer’s hardware is no longer supported by that operating system. To wrap it up, it is safe to say that Oracle VM VirtualBox can come in handy to both novices and experts: while the former can get their virtual machines up and running in no time, the latter can customize their virtualized environment to the tiniest details. Oracle VM VirtualBox also includes versatile hardware support, allowing you to create virtual machines with multiple virtual CPUs (regardless of how many cores you have physically on your PC), that recognize USB devices, or that have multi-screen resolutions, integrated iSCSI support, and PXE network boot. If you are an expert user, you can also benefit from the specialized functions of Oracle VM VirtualBox, such as shared folders, seamless windows, 3D virtualization, multi-generation branched snapshots, remote machine display and modularity. Whether you are a professional software tester or simply like to test a variety of apps before settling on the one that best meets your needs, you are probably aware that a virtualized environment can save you a lot of time: you can install any app without fear of it messing up your previous settings, and you can uninstall it just as easily. This allows you to run software designed for one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot. VirtualBox Portable allows you to run multiple operating systems at the same time. VirtualBox Portable’s features are useful in a variety of situations: Running multiple operating systems at the same time.
VirtualBox is a powerful virtualization product that can be used in both the enterprise and at home. It is now the only professional quality virtualization solution that is also Open Source Software, aimed at server, desktop, and embedded use. VirtualBox Portable is a hardware-specific full virtualizer.
