   • The virtual machine can run inside the current preferred operating system, instead of replacing it or setting up a complicated dual-boot solution.
   • A virtual machine can be snapshotted, which means the entire state of the machine is preserved and can be restored.

2. What are some of the downsides of running a virtual machine as opposed to a bare-metal installation?
   • There is a little overhead from the virtualization.
   • More resources (CPU/RAM/disk) will always be used compared to running a bare-metal installation.
