VMware to OpenStack migration script (vmware2openstack)

This script may be used to migrate VMs from VMware to an OpenStack environment.

The script itself must be run on a machine which has access to:

• the ESXI host where the VM to migrated resides on
• the OpenStack environment where the VM needs to migrated to

Usage

usage: vmware2scs.py [-h] -c CONFIG -n NAME [-fc]

VMWare to OpenStack move script

options:
  -h, --help            show this help message and exit

  -n NAME, --name NAME  Name of the server to create during migration (default: None)
  -fc, --forceCopy      Force copying of image files from ESXI if already present in data directory (default: False)

At least a configuration file and the name of the server must be given.

The server will be migrated into the configured OpenStack environment using the name given at command line.
