They are often referred to as a guest while the physical machine they run on is referred to as the host. Virtualization makes it possible to create multiple virtual machines, each with their own operating system (OS) and applications, on a single physical machine. A VM cannot interact directly with a physical computer.

What allows multiple operating systems to run on a single physical machine?
Virtualization software — programs that allow you to run multiple operating systems simultaneously on a single computer — allows you to do just that. Using virtualization software, you can run multiple operating systems on one physical machine.
Can you run multiple virtual machines at once?
Yes you can run multiple virtual machines at once. They can appear as separate windowed applications or take over the full screen. … The hard-and-fast limit to the number of VMs you can run is your computer’s memory.

How many virtual machines can be run on a single host machine?
If we look at the physical limitation of VMware ESX server, the number of virtual machines you can run is 300 virtual machines per host.
Is a technology to run multiple same or different operating systems which is completely isolated from each other?
Virtualization allows you to take a single physical device (e.g., one workstation or server) and run multiple instances of operating systems. Each of these instances looks and operates as its own device, but because they coexist on a single physical device, they are considered to be virtual machines.
Is it possible to have more than one operating system on a computer?
While most PCs have a single operating system (OS) built-in, it’s also possible to run two operating systems on one computer at the same time. The process is known as dual-booting, and it allows users to switch between operating systems depending on the tasks and programs they’re working with.
Can you be hacked through a virtual machine?
If your VM gets hacked, it’s feasible that the attacker could then escape your VM in order to run and alter programs freely on your host machine. In order to do this, your attacker must have an exploit against your virtualization software. These bugs are rare but do happen.
How much RAM do I need for a virtual machine?
8 GB RAM should be good for most situations. With 4 GB you can have a problem, depending on what you intend to do with the client OS and what else the host will be used for.
