si = connect.SmartConnect(host='vcsa', user='my_user', pwd='my_password')
content = si.RetrieveContent()

datacenters = [entity for entity in content.rootFolder.childEntity
                          if hasattr(entity, 'vmFolder')]

dc = None
for datacenter in datacenters:
    if datacenter.name == 'my_datacenter':
        dc = datacenter

search = content.searchIndex
vm = search.FindByDatastorePath(dc, '[my_datastore_name] my_vm/my_vm.vmx')

# proof:
print(vm)

NOTE: you will need to know,

• the name of your VM (and possibly its VMX file if the VM and the VMX aren't the same name)
• the name of its datastore
• the name of the datacenter
