</span>Version 4.1 of the SDK isn't very different for version 4.0. It is very<br>
different from version 3.6.<br>
<br>
Note that version 3 of the API, and version 3 of the SDK are deprecated<br>
since version 4.0 of the engine, and they will be removed in version 4.2<br>
of the engine.<br>
<br>
There is a general description of version 4 of the SDK here:<br>
<br>
<a href="https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/README.adoc" rel="noreferrer" target="_blank">https://github.com/oVirt/<wbr>ovirt-engine-sdk/blob/master/<wbr>sdk/README.adoc</a><br>
<br>
A collection of examples here:<br>
<br>
<a href="https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples" rel="noreferrer" target="_blank">https://github.com/oVirt/<wbr>ovirt-engine-sdk/tree/master/<wbr>sdk/examples</a><br>
<br>
And reference documentation here:<br>
<br>
<a href="http://ovirt.github.io/ovirt-engine-sdk/4.1" rel="noreferrer" target="_blank">http://ovirt.github.io/ovirt-<wbr>engine-sdk/4.1</a><br>
<br>
You may also find useful the documentation of the API itself:<br>
<br>
<a href="http://ovirt.github.io/ovirt-engine-api-model/4.1" rel="noreferrer" target="_blank">http://ovirt.github.io/ovirt-<wbr>engine-api-model/4.1</a><br>
<br>
Specially the section that describes how to add virtual machines, as<br>
there is an example of how to add a virtual machine from a snapshot there:<br>
<br>
<br>
<a href="http://ovirt.github.io/ovirt-engine-api-model/4.1/#services/vms/methods/add" rel="noreferrer" target="_blank">http://ovirt.github.io/ovirt-<wbr>engine-api-model/4.1/#<wbr>services/vms/methods/add</a><br>

</span>To create a virtual machine from a snapshot with the latest version of<br>
the SDK you will need something like this:<br>
<br>
---8<---<br>

ca_file='ca.pem'<br>
)<br>
<br>
# Get the reference to the root of the tree of services:<br>
system_service = connection.system_service()<br>
<br>
# Find the virtual machine:<br>
vms_service = system_service.vms_service()<br>
vm = vms_service.list(search='name=<wbr>myvm')[0]<br>
<br>
# Find the service that manages the virtual machine:<br>
vm_service = vms_service.vm_service(<a href="http://vm.id" rel="noreferrer" target="_blank">vm.id</a>)<br>
<br>
# Find the snapshot. Note that the snapshots collection doesn't support<br>
# search, so we need to retrieve the complete list and the look for the<br>
# snapshot that has the description that we are looking for.<br>
snaps_service = vm_service.snapshots_service()<br>
snaps = snaps_service.list()<br>
snap = next(<br>
(s for s in snaps if s.description == 'mysnap'),<br>
None<br>
)<br>
<br>
# Create a new virtual machine, cloning it from the snapshot:<br>

cloned_vm_service = vms_service.vm_service(<a href="http://cloned_vm.id" rel="noreferrer" target="_blank">cloned_<wbr>vm.id</a>)<br>
<br>
# Wait till the virtual machine is down, as that means that the creation<br>
# of the disks of the virtual machine has been completed:<br>

time.sleep(5)<br>
cloned_vm = cloned_vm_service.get()<br>
if cloned_vm.status == types.VmStatus.DOWN:<br>
break<br>
<br>
# Close the connection to the server:<br>
connection.close()<br>
