similar way perl sdk works on single ESXi 6.5, 6.7 to list down vm on ESXi without any vcenter or vsphere server attached to ESXi

but in python it is not working. any one have any idea.

[doskiran · Accepted solution]

vSphere Automation SDK works only with vCenter sessions.

Because there are no public APIs for ESXi VMODL2.

To achieve your task use pyVmomi.
> pyVmomi(SOAP based) allows you to manage VMware ESXi and vCenter using Python.

pyVmomi: https://github.com/vmware/pyvmomi

Note: Mentioned perl SDK is also a SOAP-based( vSphere Web Services API) integration point for the vSphere Management SDK.

Sample program to list all VMs under ESXi/vCenter:

from pyVim.connect import SmartConnect
import ssl

s = ssl.create_default_context(purpose=ssl.Purpose.CLIENT_AUTH)
s.verify_mode = ssl.CERT_NONE

si = SmartConnect(
    host="<vCenter or ESXi server>",
    user="root",
    pwd="<passw0rd>",
    port=443,
    sslContext=s,
)

content = si.RetrieveContent()
for child in content.rootFolder.childEntity:
    if hasattr(child, "vmFolder"):
        datacenter = child
        vmFolder = datacenter.vmFolder
        vmList = vmFolder.childEntity
        for vm in vmList:
            summary = vm.summary
            print("VM Name: ", summary.config.name)
