Using the API # Check if there's a VM by the uuid specified ${XE} vm-list params=uuid | grep -q " ${vmuuid}$" if [ $? -ne 0 ]; then echo "error: no vm uuid \"${vmuuid}\" found" exit 2 fi The script then checks the power state of the VM and if it is running, it attempts a clean shutdown. The event system is used to wait for the VM to enter state "Halted". Note The XE CLI supports a command-line argument --minimal which causes it to print its output without excess whitespace or formatting, ideal for use from scripts. If multiple values are returned they are comma-separated. # Check the power state of the vm name=$(${XE} vm-list uuid=${vmuuid} params=name-label --minimal) state=$(${XE} vm-list uuid=${vmuuid} params=power-state --minimal) wasrunning=0 # If the VM state is running, we shutdown the vm first if [ "${state}" = "running" ]; then ${XE} vm-shutdown uuid=${vmuuid} ${XE} event-wait class=vm power-state=halted uuid=${vmuuid} wasrunning=1 fi The VM is then cloned and the new VM has its name_label set to cloned_vm. # Clone the VM newuuid=$(${XE} vm-clone uuid=${vmuuid} new-name-label=cloned_vm) Finally, if the original VM had been running and was shutdown, both it and the new VM are started. # If the VM state was running before cloning, we start it again # along with the new VM. if [ "$wasrunning" -eq 1 ]; then ${XE} vm-start uuid=${vmuuid} ${XE} vm-start uuid=${newuuid} fi 23
