When developing for bootstrap-vz, testing can be quite tedious since the bootstrapping process can take a while. The prebootstrapped plugin solves that problem by creating a snapshot of your volume right after all the software has been installed. The next time bootstrap-vz is run, the plugin replaces all volume preparation and bootstrapping tasks and recreates the volume from the snapshot instead.

The plugin assumes that the users knows what he is doing (e.g. it doesn’t check whether bootstrap-vz is being run with a partitioned volume configuration, while the snapshot is unpartitioned).

When no snapshot or image is specified the plugin creates one and outputs its ID/path. Specifying an ID/path enables the second mode of operation which recreates the volume from the specified snapshot instead of creating it from scratch.


  • snapshot: ID of the EBS snapshot to use. This setting only works with the volume backing ebs.
  • image: Path to the loopbackvolume snapshot. This setting works with the volume backings raw, s3, vdi, vmdk
  • folder: Path to the folder copy. This setting works with the volume backing folder
