If the source VM has any snapshot information that you want to copy you first need to merge the snapshot(s) into the source VM’s disk image files. With respect to copying the important thing to understand about snapshots is that there is no easy way to copy them, so if your source VM has any snapshot information that you want to copy you first need to merge the snapshot(s) into the source VM’s disk images. If there are no snapshots the VM’s disk image file accumulates file system changes just like normal disks¿-¿the VM’s Current State is merged into the disk image automatically when you close the VM. When you create a snapshot, changes to the file system accumulate in the current snapshot file, older snapshot files and disk image files are effectively read-only. You return to a previous snapshot by deleting the current state and all newer snapshots. XML configuration files defining the VM (virtual hardware parameters).Ī snapshot bookmarks the state of the VM (specifically the VM file system) at the point in time the snapshot is made. One or more virtual hard disk image files (VDI files). Before starting it helps to have a basic understanding of VirtualBox virtual machines. This article explains how to copy an existing VM containing an installed and configured guest OS. The good news is that the underlying technology is just great and with a little understanding copying and cloning VMs is quite easy. There is no single VirtualBox command for VM cloning.Ī couple of the VirtualBox commands are poorly named. Cloning and copying VirtualBox VMs is not as straight forward or obvious as it is with VMWare Desktop and this subject has created a lot of confusion in the support forums. ![]()
