It enables you to run multiple operating systems and applications on a single physical machine, providing enhanced flexibility, scalability, and cost-effectiveness. With virtual machines, you can create isolated environments, test software, and run legacy applications without the need for additional hardware.
One of the key features offered by virtual machines is the ability to take snapshots. A snapshot is a saved state of a virtual machine at a specific point in time. It captures the VM’s disk and memory states, allowing you to revert back to that exact point if needed.
Reverting to a snapshot means restoring your VM to a previous state. This can be useful when you want to undo changes, troubleshoot issues, or quickly recover from an unexpected event. However, reverting to a snapshot can be a time-consuming process, requiring the virtual machine to go through its boot sequence and reinitialize its services.
Suspending a virtual machine, on the other hand, means pausing the VM’s operation and saving its current state to disk. It allows you to quickly resume your work from where you left off without going through the entire boot process. This feature is especially handy when you need to revert to a selected snapshot, as it eliminates the waiting time and improves overall efficiency.
In this article, we will explore the benefits of suspending a virtual machine when reverting to a selected snapshot. We will also provide step-by-step instructions on how to suspend a VM when reverting, ensuring a smooth and streamlined experience. So, let’s dive in and discover how this technique can enhance your virtual machine management workflow!
What is a virtual machine?
A virtual machine (VM) is a software emulation of a physical computer system. It allows you to run multiple operating systems and applications simultaneously on a single physical machine. Think of it as a computer within a computer.
Virtual machines are created using virtualization software, such as VMWare, Hyper-V, or VirtualBox. These software programs enable you to allocate resources from your physical machine, such as CPU, memory, storage, and network, to the virtual machine.
By isolating the hardware resources and abstracting them, virtual machines provide a flexible and scalable environment. Each virtual machine operates independently and can have its own operating system, applications, and settings. This enables you to streamline your software testing, development, and deployment processes.

Furthermore, virtual machines provide a secure environment for testing and experimentation. You can take snapshots of a virtual machine’s state, which allows you to revert back to a known configuration if something goes wrong. This ensures that any changes or modifications made to the virtual machine can be easily rolled back.
Overall, virtual machines provide a powerful and flexible solution for running multiple operating systems and applications on a single physical machine. They offer numerous benefits, including cost savings, resource optimization, and enhanced security. By utilizing virtual machines, you can streamline your workflow and maximize productivity.
What is a snapshot?
A snapshot is a saved state of a virtual machine at a specific point in time. It captures the disk and memory states of the virtual machine, allowing you to return to that exact state later on.
When you take a snapshot of a virtual machine, it creates a read-only copy of the VM’s disk at that particular moment. This copy contains all the data and configuration settings of the VM, including the operating system, installed applications, files, and user settings.
One of the most significant advantages of using snapshots is the ability to experiment and make changes to a virtual machine without the fear of irreversible consequences. Before making any substantial modifications or updates, you can take a snapshot as a backup, creating a restore point to fall back on if needed.
Snapshots are commonly used for testing purposes. They allow you to perform software installations, updates, or configuration changes on a virtual machine, knowing that you can easily revert back to the snapshot if any issues arise. This ensures that critical production environments remain unaffected by potentially disruptive changes.
In addition, snapshots play a vital role in the development and debugging process. If an application encounters a bug or crash, you can revert the virtual machine back to a snapshot taken before the issue occurred. This allows you to analyze the problem in a controlled environment and work towards finding a solution without impacting the rest of your system.
Furthermore, snapshots are useful when dealing with complex system configurations or network setups. For instance, if you have a virtual machine acting as a server with numerous specific settings, you can take a snapshot once the system is configured correctly. This snapshot serves as a blueprint that you can return to if the server encounters any problems or if you need to recreate the exact environment for future use.
It is important to note that while snapshots are valuable for backup and restore purposes, they should not be considered a substitute for regular backups. Snapshots primarily capture the disk and memory state of a virtual machine, but they do not capture any external data or files stored outside of the VM. Therefore, it is advisable to regularly back up important files separately from the snapshots.
Overall, snapshots provide a convenient and efficient way to capture and restore the state of a virtual machine at a particular moment in time. They offer flexibility, reliability, and peace of mind by allowing you to experiment, troubleshoot, and make changes without the fear of permanent consequences.
What is reverting to a snapshot?
Reverting to a snapshot refers to the process of restoring a virtual machine to a previously saved snapshot state. It allows you to roll back the VM’s disk and memory states to a specific point in time, effectively undoing any changes or modifications made after that snapshot was taken.
When you revert to a snapshot, the virtual machine’s current state is replaced with the saved state of the snapshot. This means that any changes you have made since the snapshot was taken will be discarded, and the virtual machine will return to the exact state it was in at the time of the snapshot.
Reverting to a snapshot can be extremely useful in various scenarios. For example, if you are testing new software or making system configuration changes, and something goes wrong, reverting to a snapshot can quickly bring your virtual machine back to a known and stable state.
This feature is particularly beneficial for developers who frequently need to test different configurations or experiment with various software environments. If an update or modification causes unexpected issues, reverting to a snapshot allows them to start fresh without needing to recreate or reinstall everything from scratch.
Reverting to a snapshot can also be valuable in troubleshooting scenarios. For instance, if a virtual machine encounters performance issues or crashes after a recent change, reverting to a snapshot that was taken before the problem occurred can help isolate the root cause and properly diagnose the issue.
It’s worth noting that reverting to a snapshot is not a substitute for regular backups. While reverting to a snapshot can restore the virtual machine’s state, it does not capture any external data or files stored outside of the virtual machine itself. Therefore, it is crucial to maintain regular backups of important files and data to ensure their safety and availability.
Overall, reverting to a snapshot provides a powerful and efficient way to undo changes and restore a virtual machine to a previously known and stable state. Whether you’re encountering issues with software updates, testing different configurations, or troubleshooting problems, reverting to a snapshot offers a reliable solution to bring your virtual machine back to a desired state with minimal effort and potential downtime.
What is suspending a virtual machine?
Suspending a virtual machine involves pausing the VM’s operation and saving its current state to disk. Instead of completely shutting down the virtual machine, suspending allows you to freeze its activity and preserve the memory and disk state.
When you suspend a virtual machine, the RAM contents and disk state are written to the VM’s storage disk or file. This means that the virtual machine’s current session, open applications, running processes, and data held in memory are stored for later use.
Upon resuming a suspended virtual machine, it restores the saved state from disk, allowing you to continue exactly where you left off. This eliminates the need to go through the entire boot process and reinitialize any services or applications that were running at the time of suspension.
Suspending a virtual machine is similar to putting a physical computer into a sleep or hibernation mode. It allows you to conserve resources and quickly resume work without having to wait for the virtual machine to boot up and load all the necessary components.
This feature is particularly valuable when you need to revert a virtual machine to a selected snapshot. By suspending the VM before reverting, you can bypass the time-consuming boot process and significantly reduce the waiting time.
In addition to snapshot reverting, suspending a virtual machine can be beneficial in various other scenarios. For example, if you need to temporarily free up system resources or pause a long-running task, suspending a VM provides a convenient way to halt its operation without losing any data or progress.
Suspending a virtual machine is also advantageous when you need to switch between multiple virtual machines on a single physical host. Instead of shutting down one VM to start another, you can suspend the first VM, allowing you to quickly return to it later without any interruptions.
It is important to note that while suspending a virtual machine can provide quick and efficient work resumption, it is not a solution for long-term storage or backup needs. Suspended virtual machines rely on the memory and storage resources of the physical host, and they should not be used as a substitute for regular virtual machine backups.
In summary, suspending a virtual machine allows you to temporarily pause its operation and save its current state to disk. It provides a convenient way to conserve resources, quickly resume work, and significantly reduce the waiting time when reverting to a selected snapshot. Understanding how to use this feature effectively can enhance your virtual machine management workflow and improve overall productivity.
