list of virtual machines with snapshots

[Fernando Moreira]

Hi,

I would like to know if anyone has a script that can list all the virtual machines that are running with snapshots.

Thanks a lot for your help.

Fernando

Ok so I've done this.

from pysphere import VIServer
import getpass
import sys

if len(sys.argv) < 2:
    sys.exit('Usage: %s vCenter-name user-name' % sys.argv[0])

vCenter=sys.argv[1]
username=sys.argv[2]

Password=getpass.getpass(prompt='Enter password for vCenter '+vCenter+' for user '+username+' : ')

server = VIServer()
server.connect(vCenter, username, Password)

print "Server type: ",server.get_server_type()
print "Running version: ", server.get_api_version()

# vmlist = server.get_registered_vms(cluster='MCLIENTTST',status='poweredOn')
vmlist = server.get_registered_vms(status='poweredOn')

print len(vmlist)

for vm_path in vmlist:
    vm_name=server.get_vm_by_path(vm_path)
    vm_real_name=vm_name.get_property('name')
    vm_snapshots=vm_name.get_snapshots()
    if len(vm_snapshots) > 0:
        print vm_real_name,"has snapshots"
server.disconnect()

It works fine but it is very slow, I think I need to understand the concept of MOR to make it quicker but as I am learning Python and the pysphere API, I am not sure on how to go about it.

Thanks a lot for this API Seba :)

Hi Fernando,

   I was on holiday, I'm sorry I couldn't reply before.

This should be much faster:

s = VIServer()
s.connect(HOST, USER, PASSWORD)

result = s._retrieve_properties_traversal(
                            property_names=['name', 'rootSnapshot'],
                            obj_type="VirtualMachine")

for props in result:
    has_snapshots = False
    name = ""
    for ps in props.PropSet:
        if ps.Name=='rootSnapshot' and ps.Val.ManagedObjectReference:
            has_snapshots = True
        if ps.Name=='name':
            name = ps.Val
    if has_snapshots:
        print name, "has snapshots"

Saludos!

Sebastián.

Thanks a lot Seba, that's very useful and Thanks for the pysphere, it's the kick I needed to start learning Python :)

This is crazy fast, and crazy helpful!

Would you be able to extend this to also list the snapshots (vm can have multiple), and their age?

Same python module is not working for me, do you have any clue?

>>> import pysphere
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

I am using python 3.12.8 on RHEL 8:10 server.

# uname -r
   4.18.0-553.27.1.el8_10.x86_64

#

# python --version
   Python 3.12.8
#

# pip list | grep pysphere
    pysphere           0.1.7

Sorry, this is a very old library, no longer maintained, it was never ported to python 3
