Virtual Box in Linux for Windows


Hello, everyone!

I am very new to the theme "virtual machine", and have basic questions. As I have read in sites in Internet, Virtual Box would be appropriate for my PC, that has both Linux and Windows installed.

My question is very simple: after I download and install Virtual Box through Linux, must I install a Windows-ISO file? I have Windows already installed in my PC, and would like to use its features like "Word" without needing to reboot the machine. Would you have any tips for me after installing Virtual Box?

Thanks in advance!

VirtualBox is in a nutshell is creating a physical server within an operating system. VirtualBox is installed on the host operating system and then from VB you would install the virtual operating system which is known as the guest.

The host operating system can be Windows or linux and you can install either as a guest virtual machine (VM). It might be easier to start with installing VirtualBox on Windows and creating a linux VM.

"creating a physical server" To expand on that, virtual software copy of a physical machine. Some software creates a clone of some original computer.

Here is the problem with running Windows as a client in linux vm. Windows has this HAL deal. It doesn't like to be run in different machines (unless you have a special copy).

Most folks own windows from an computer company supplied copy. It is not a full copy from MS. The computer company supplied copy is usually tied to the bios of the computer. Since a VM replicates most of the hardware from software you won't be able to authenticate the copy by the host hardware.

Every year VM's and hardware find ways to integrate the host hardware more closely with the VM. They are not fully host centric yet.

Thank you very much for your information. Actually I do work in a company with a computer in which Windows was already installed. I myself installed Linux in it later, without uninstalling Windows. I use Linux most of the time, but sometimes I have to use Windows, and for this reason I plan to install a virtual machine in Linux. Don't you think it is advisable? Thank you again.

you can do that, but probably that windows (inside linux) will not be fast. You need to reinstall windows for that (you cannot use the existing os).

Most modern middle to higher end systems are quite capable of running a number of VM's at the same time usually. There may be some video issues with windows. The most modern systems have good integration with a VM client to host. Only if you have the most modern system will you be able to run higher quality games. Any business use should be OK.

If you can run Windows will depend on how you own it. Do you know what HAL is and what windows needs to authenticate?

That would depend on how much RAM the host machine has and what portion of it can be devoted to the virtual machine.

The computer I'm sitting at has 16 GB RAM. I allocated 4 GB to my Windows 7 VM, and it runs quite nicely.

In my experience, VirtualBox's default allocations of RAM and virtual HDD space are usually far too small.
