One of the greatest features when using virtualization is the ability to use snapshots. Snapshots allow for a virtual machine state and configuration to be captured and then later, rolled back to undo any changes. This is a great method to test our changes on virtual machines, by snapshotting the VM prior to making the change, it can be rolled back if the result is undesired.
In this recipe we will be working with our Accounting02 virtual machine created in the Creating virtual machines recipe.
In this fictional scenario we have an application team that is planning to make two different sets of changes to our VM. In order to facilitate troubleshooting and recovery, we will be creating several snapshots of the VM before and during the activity. If needed, we will rollback the snapshots to a working condition.
