Please note that the exact steps may vary depending on the virtualization software and the operating system running inside the virtual machine.
Shared Folders and Clipboard VM
In virtualization, a virtual machine (VM) is an isolated environment that runs within a host system. Shared folders and clipboards are two common features that allow for easy file and data transfer between the host and guest operating systems.
Shared folders allow you to share files and folders between the host and guest operating systems. This is particularly useful when you need to transfer files from the host to the guest or vice versa. With shared folders, you can specify which folders on the host system you want to share and which folders on the guest system can access them.
Clipboard sharing, on the other hand, allows you to copy and paste data between the host and guest operating systems. This feature is particularly useful when you need to transfer text or other data between the two systems. With clipboard sharing, you can copy text or other data on the host system and paste it into the guest system, or vice versa.
Both shared folders and clipboard sharing can be enabled or disabled for each VM in your virtualization software. The exact steps to enable these features may vary depending on the virtualization software you are using, but typically you can enable them in the settings of the VM. However, it's important to note that enabling these features can also increase the security risks associated with running a VM, so it's important to only enable them if necessary and to take appropriate security measures to protect your system.
Making a Virtual Machine (VM) Copy
Creating a copy of a virtual machine (VM) can be useful for a variety of reasons, such as testing software updates, creating a backup of the VM, or deploying multiple instances of the same VM. The specific steps for making a VM copy will depend on the virtualization software being used, but in general, the process involves the following steps:
1. Shut down the VM: Before making a copy of the VM, it's important to ensure that the virtual machine is powered off.
2. Create a clone: In most virtualization software, creating a copy of a VM is referred to as "cloning" the VM. This process involves creating a new virtual machine that is an exact copy of the original VM, including all of its settings, configurations, and data.
3. Choose a destination: When creating a clone of a VM, you'll typically be asked to specify where the copy should be saved. This could be a different folder on the same physical host, or it could be stored on a separate physical server or storage device.
4. Configure the clone: Once the cloning process is complete, you may need to make some adjustments to the cloned VM. For example, you may need to change its name, IP address, or network settings to avoid conflicts with the original VM.
5. Power on the clone: Finally, you can power on the cloned VM and begin using it just like you would the original. Keep in mind that because the clone is an exact copy of the original, any changes made to one VM will not be reflected in the other.
Using Snapshots VM
Snapshots are a feature in virtual machine (VM) software that allows you to save a copy of the VM at a specific point in time. This copy is called a snapshot, and it can be used to restore the VM to its previous state if necessary. Here are some steps on how to use snapshots in VM software:
1. Create a snapshot: To create a snapshot of a VM, you first need to power off the VM. Then, in the VM software, select the VM and choose the option to create a snapshot. Give the snapshot a name and description so that you can easily identify it later.
2. Take regular snapshots: It's a good idea to take regular snapshots of your VM, especially before making any major changes or updates. This way, if something goes wrong, you can easily restore the VM to its previous state.
3. Use snapshots to restore: To restore a VM from a snapshot, simply select the snapshot you want to restore to and choose the option to revert to that snapshot. This will restore the VM to the state it was in when the snapshot was taken.
4. Delete old snapshots: It's important to periodically delete old snapshots to free up disk space. However, make sure you keep at least one snapshot as a backup in case you need to restore the VM to a previous state.
Using snapshots can be a powerful tool for managing VMs, but it's important to use them carefully and make sure you have a good backup strategy in place.
How to use VirtualBox for taking VM snapshots

4. Enter a name and description for the snapshot and click "OK."
5. Wait for VirtualBox to create the snapshot, which may take a few minutes depending on the size of the virtual machine.
6. Once the snapshot is created, you can make changes to the virtual machine, knowing that you can always revert to the snapshot if needed.
7. To revert to a snapshot, select the snapshot from the list in the Snapshots Manager and click on the "Restore" button.
8. If you want to delete a snapshot, select it from the list in the Snapshots Manager and click on the "Remove" button.
Note that taking snapshots of a virtual machine can take up a significant amount of disk space, especially if you take multiple snapshots. Make sure you have enough free space on your hard drive before taking snapshots.
Recording Video Virtual machine In VirtualBox
