4.3.2. Cloning a VM via the XE CLI

This example (contained in /SDK/client-examples/bash-cli/clone-vms) is a bash script which

uses the XE CLI to clone a VM taking care to shut it down first if it is powered on.

The example begins with some boilerplate which first checks if the environment variable XE has been set: if

it has it assumes that it points to the full path of the CLI, else it is assumed that the XE CLI is on the current

path. Next the script prompts the user for a server name, username and password:

# Allow the path to the 'xe' binary to be overridden by the XE environment varia

ble

if [ -z "${XE}" ]; then

XE=xe

if [ ! -e "${HOME}/.xe" ]; then

read -p "Server name: " SERVER

read -p "Username: " USERNAME

read -p "Password: " PASSWORD

XE="${XE} -s ${SERVER} -u ${USERNAME} -pw ${PASSWORD}"

Next the script checks its commandline arguments. It requires exactly one: the UUID of the VM which is

to be cloned:
