Managing snapshots
In this section, we are going to see how to create snapshots of a KVM-based VM and roll back to the previous state.
Getting ready
Snapshots can be created and rolled back through the Proxmox GUI. The Snapshots menu is only available through a VM-specific tabbed menu.
How to do it…
The following steps show how to create a snapshot of a VM:
Select a VM for which snapshots need to be created and click on the Snapshots tabbed menu.
Click on Take Snapshot to open a dialog box.
Enter the name of the snapshot. The string must start with at least one alphabetic letter.
If the snapshot is being created for a powered up VM, then select the Include RAM checkbox or else uncheck it.
Note
This option will save the state of a running VM, saving the content of the memory. If it is not selected, then the snapshot is created only for the disk image. This can lead to filesystem inconsistency when reverting back.
Enter a description for the snapshot.
Click on the Take Snapshot button to create the snapshot...
