Subjects
Current State
The "current state" represents the "now" point in the life time of the virtual machine. The current state can be preserved by taking a snapshot.
Clone
Full Clone
A clone that copies all depending disk images into the new VM folder. A full clone can fully operate without the source VM.
Linked Clone
A linked clone refers to parent disk images.
Cloning "Everything"
If "Everything" is chosen when cloning, the current state of the VM and all snapshots are cloned.
Snapshot
A snapshot contains the current state of the virtual machine, which consists of:
- the complete copy of the VM settings, including the hardware configuration.
- the complete state of all virtual disks attached to the VM. Going back to a past snapshot means that all changes that have been made since the snapshot has been taken will be discarded.
- if the snapshot was taken when the machine is running, the memory state is preserved as well.
