Examples

Some basic examples are included here for common functionality. For more detailed information, see the generated documentation.

Initialize a client

import esxi_utils
client = esxi_utils.ESXiClient("<ip>", "<username>", "<password>")

Note: The remaining examples will assume an already-initialized client.

Get Virtual Machine Information

# Print all VM names
print("All VMs: " + str(client.vms.names))

# Check if a VM exists
if "MyVirtualMachine" not in client.vms:  # Or more explicitly: if not client.vms.exists("MyVirtualMachine"):
   raise Exception("VM does not exist")

# Get a VM object
vm = client.vms["MyVirtualMachine"]       # Or more explicitly: vm = client.vms.get("MyVirtualMachine")

# Print this VMs information
print("Name: " + vm.name)
print("ID: " + str(vm.id))
print("UUID: " + vm.uuid)
print("Name of datastore containing this VM: " + vm.datastore.name)
print("Is powered on: " + str(vm.powered_on))
print("Number of VCPUs: " + str(vm.vcpus))
print("MB of memory: " + str(vm.memory))
print("VM OS Type: " + vm.guestid)

for disk in vm.disks:
   print("Disk size (KB): " + str(disk.size))

for nic in vm.nics:
   print("Network: " + nic.network + " (IP: " + nic.ip + ")")

for cdrom in vm.cdroms:
   print("CD-ROM: " + str(cdrom.file))

for snapshot in vm.snapshots:
   print("Snapshot: name=" + snapshot.name + ", description=" + snapshot.description + ", created=" + str(snapshot.createtime))

Create a new Virtual Machine and Add Hardware

vm = client.vms.create(
   name="MyNewVirtualMachine",
   datastore="MyDatastore",
   vcpus=1,
   memory="2GB",
   guestid="rhel7_64Guest"
)

# Add a disk
vm.disks.add("10GB")

# Add a NIC
vm.nics.add("Test-Network")

# Add a CD
cdrom_file = client.datastores["MyDatastore"].filepath("my-file.iso")	# Or: client.datastores["MyDatastore"].root / "my-file.iso"
cdrom = vm.cdroms.add(cdrom_file)
cdrom.start_connected = True

# Add a Floppy
floppy_file = client.datastores["MyDatastore"].filepath("my-floppy.img")
floppy = vm.floppies.add(floppy_file)
floppy.start_connected = True

Modify an existing Virtual Machine

vm = client.vms["MyVirtualMachine"]

vm.power_off()                  # Power off the virtual machine
vm.memory = "8GB"               # Set memory to 8GB
vm.vcpus = 4                    # Set number of VCPUs to 4
vm.guestid = "rhel7_64Guest"    # Set ESXi OS Type

# Modify a NIC
nic = vm.nics["External"]               # Get the NIC for network "External"; Or more explicitly: nic = vm.nics.get("External")
nic.network = "Management-Network"      # Change the NIC's network to "Management-Network"
nic.connected = True                    # Connect the NIC

# Remove a NIC
vm.nics["Other-Network"].remove()

# Resize the first disk
vm.disks[0].size = "32GB"

# Remove the second disk
vm.disks[1].remove()

# Change the CD-ROM file
vm.cdroms[0].file = client.datastores["MyDatastore"].filepath("installer.iso")

# Change the floppy file
vm.floppies[0].file = client.datastores["MyDatastore"].filepath("kickstart.img")

Work with Virtual Machine Snapshots

vm = client.vms["MyVirtualMachine"]

# Create a new snapshot
vm.snapshots.create("MyNewSnapshot", description="This is a new snapshot")

# Remove the current snapshot
vm.snapshots.current.remove(remove_children=True)

# Revert to an old snapshot
vm.snapshots["MyOldSnapshot"].revert()

Upload a Virtual Machine from OVF or OVA

vm = client.vms.upload(
   file="./path/to/file.ovf",
   datastore="MyDatastore",
   name="MyNewVirtualMachine",
   network_mappings={ "Original-Network": "New-Network" }
)

vm.power_on()

Export a Virtual Machine to OVF or OVA

client.vms["MyVirtualMachine"].export(
   path="./path/to/export/folder",
   format="ova",
   hash_type="sha256",
   include_image_files=False,
   include_nvram=True
)

Clone a Virtual Machine

vm = client.vms["MyVirtualMachine"].clone("MyNewVirtualMachine")
vm.power_on()

Print Networking Information

print("Host VSwitches:")
for vswitch in client.vswitches:
	print("\tName:" + vswitch.name)
	print("\t\tMTU: " + str(vswitch.mtu))
	print("\t\tPorts Available: " + str(vswitch.numports_available) + " / " + str(vswitch.numports))
	print("\t\tPort groups:")
	for portgroup in vswitch.portgroups:
		print("\t\t\t- " + portgroup.name)
print()

print("Host Port Groups:")
for portgroup in client.portgroups:
	print("\tName: " + portgroup.name)
	print("\t\tVLAN: " + str(portgroup.vlan))
	print("\t\tActive Clients: " + str(portgroup.active_clients))
	print("\t\tVSwitch: " + portgroup.vswitch.name)
	print("\t\tConnected VMs:")
	for vm in portgroup.vms:
		print("\t\t\t- " + vm.name)
print()

print("Host Physical NICs:")
for pnic in client.physicalnics:
	print("\tName: " + pnic.name)
	print("\t\tUp: " + str(pnic.up))
	print("\t\tLink Speed (MB): " + str(pnic.linkspeed))
	print("\t\tFull Duplex: " + str(pnic.fullduplex))
print()

print("Host VMKernel NICs:")
for vnic in client.vmkernelnics:
	print("\tName: " + vnic.name)
	print("\t\tPort Group: " + str(vnic.portgroup))
	print("\t\tIP: " + vnic.ip)
	print("\t\tSubnet: " + vnic.subnetmask)
	print("\t\tMTU: " + str(vnic.mtu))

Modify Networking

# Check if a virtual switch exists
exists = "MyVirtualSwitch" in client.vswitches
print("VSwitch exists: " + str(exists))

# Check if a port groups exists
exists = "MyPortGroup" in client.portgroups
print("PortGroup exists: " + str(exists))

# Add new virtual switch and port groups
vswitch = client.vswitches.add("TestVSwitch")
vswitch.add("TestPortGroup", vlan=70)
vswitch.add("TestPortGroup2", vlan=80)

# Remove a port group from a virtual switch
client.vswitches["TestVSwitch"].portgroups[0].remove()

# Remove a virtual switch
client.vswitches["TestVSwitch"].remove()

# Add a port group to an existing virtual switch
client.vswitches["AVirtualSwitch"].add("APortGroup", vlan=0)
client.vswitches["AVirtualSwitch"].add("APortGroup2", vlan=4095)
