}The changeVersion is a unique identifier for a given version of the configuration.
Each change to the configuration updates this value. This is typically implemented as an ever increasing count or a time-stamp. However, a client should always treat this as an opaque string.
Last time a virtual machine's configuration was modified.
Display name of the virtual machine.
Any / (slash), \ (backslash), character used in this name element is escaped. Similarly, any % (percent) character used in this name element is escaped, unless it is used to start an escape sequence. A slash is escaped as %2F or %2f. A backslash is escaped as %5C or %5c, and a percent is escaped as %25.
This is the full name of the guest operating system for the virtual machine.
For example: Windows 2000 Professional.
See also VirtualMachineConfigInfo.alternateGuestName.
The version string for this virtual machine.
128-bit SMBIOS UUID of a virtual machine represented as a hexadecimal string in "12345678-abcd-1234-cdef-123456789abc" format.
Time the virtual machine's configuration was created.
VirtualCenter-specific 128-bit UUID of a virtual machine, represented as a hexademical string.
This identifier is used by VirtualCenter to uniquely identify all virtual machine instances, including those that may share the same SMBIOS UUID.
A 64-bit node WWN (World Wide Name).
These WWNs are paired with the VirtualMachineConfigInfo.npivPortWorldWideName to be used by the NPIV VPORTs instantiated for the virtual machine on the physical HBAs of the host. A pair of node and port WWNs serves as a unique identifier in accessing a LUN, so that it can be monitored or controlled by the storage administrator.
If this property contains a single node WWN, the same node WWN is used to pair with all port WWNs listed in VirtualMachineConfigInfo.npivPortWorldWideName. If this property or VirtualMachineConfigInfo.npivPortWorldWideName is empty or unset, NPIV WWN is disabled for the virtual machine.
A 64-bit port WWN (World Wide Name).
For detail description on WWN, see VirtualMachineConfigInfo.npivNodeWorldWideName.
The source that provides/generates the assigned WWNs.
See also VirtualMachineConfigInfoNpivWwnTypeEnum.
The NPIV node WWNs to be extended from the original list of WWN nummbers.
This property should be set to desired number which is an aggregate of existing plus new numbers. Desired Node WWNs should always be greater than the existing number of node WWNs
The NPIV port WWNs to be extended from the original list of WWN nummbers.
This property should be set to desired number which is an aggregate of existing plus new numbers. Desired Node WWNs should always be greater than the existing number of port WWNs
This property is used to enable or disable the NPIV capability on a desired virtual machine on a temporary basis.
When this property is set NPIV Vport will not be instantiated by the VMX process of the Virtual Machine. When this property is set port WWNs and node WWNs in the VM configuration are preserved.
This property is used to check whether the NPIV can be enabled on the Virtual machine with non-rdm disks in the configuration, so this is potentially not enabling npiv on vmfs disks.
Also this property is used to check whether RDM is required to generate WWNs for a virtual machine.
Hash incorporating the virtual machine's config file location and the UUID of the host assigned to run the virtual machine.
Flag indicating whether or not a virtual machine is a template.
Guest operating system configured on a virtual machine.
This is a guest identifier that can be used to access the GuestOsDescriptor list for information about default configuration. For more information on possible values, see VirtualMachineGuestOsIdentifier.
Used as display name for the operating system if guestId is other or other-64.
See also VirtualMachineConfigInfo.guestFullName.
Description for the virtual machine.
The FileInfo data object type contains the locations of virtual machine files other than the virtual disk files.
The configurable parameters are all in the FileInfo object.
The object also contains a FileLayout object that returns a complete list of additional files that makes up the virtual machine configuration. This is a read-only structure and is returned when the configuration is read. This is ignored during configuration and can be left out.
ToolsConfigInfo is a data object type containing settings for the VMware Tools software running in the guest operating system.
The FlagInfo data object type encapsulates the flag settings for a virtual machine.
These properties are optional since the same structure is used to change the values during an edit or create operation.
Preferences for the legacy console application that affect the way it behaves during power operations on the virtual machine.
The DefaultPowerOpInfo data object type holds the configured defaults for the power operations on a virtual machine.
The properties indicated whether to do a "soft" or guest initiated operation, or a "hard" operation.
Whether the next reboot will result in a power off.
Since: vSphere API Release 8.0.0.1
The VirtualHardware data object type contains the complete configuration of the hardware in a virtual machine.
Vcpu configuration.
The vcpuConfig array is indexed by vcpu number.
The ResourceAllocationInfo data object specifies the reserved resource requirement as well as the limit (maximum allowed usage) for a given kind of resource.
This is specified for both memory allocation (specified in MB) and CPU allocation (specified in MHz).
For a ResourcePool, the ResourceAllocationInfo object describes both the guaranteed amount of the resource (reservation) and whether or not it is expandable (expandableReservation). If expandableReservation is true, then the resource pool can grow its reservation dynamically by borrowing unreserved resources from its parent resource pool. For the methods CreateResourcePool, CreateVApp and ImportVApp, you must provide values for all properties except overheadLimit; they are not optional. (Currently, overheadLimit is for vCenter Server use only.)
If the limit is configured, it must be greater than or equal to the reservation.

If the limit is configured, it must be greater than or equal to the reservation.
Specification of the latency-sensitivity information.
The latency-sensitivity is used to request from the kernel a constraint on the scheduling delay of the virtual CPUs or other resources. This allows latency-sensitive applications(e.g. VOIP, audio/video streaming, etc.) to run in a virtual machine which is configured to use specific scheduling latencies and to be scheduled with low latency.
The kernel does not provide any guarantee that it will meet the latency-sensitivity requirement of a virtual machine CPU or other resources but it will always accept the latency-sensitivity value provided.
Whether memory can be added while this virtual machine is running.
Whether virtual processors can be added while this virtual machine is running.
Whether virtual processors can be removed while this virtual machine is running.
The maximum amount of memory, in MB, than can be added to a running virtual machine.
This value is determined by the virtual machine and is specified only if VirtualMachineConfigInfo.memoryHotAddEnabled is set to true.
Memory, in MB that can be added to a running virtual machine must be in increments of this value and needs be a multiple of this value.
This value is determined by the virtual machine and is specified only if VirtualMachineConfigSpec.memoryHotAddEnabled has been set to true.
Specification of scheduling affinity.
Scheduling affinity is used for explicitly specifying which processors or NUMA nodes may be used by a virtual machine.
Specification of scheduling affinity.
Scheduling affinity is used for explicitly specifying which processors or NUMA nodes may be used by a virtual machine.
Network traffic shaping specification.
Traffic shaping is used to configure the network utilization characteristics of a virtual machine.
Additional configuration information for the virtual machine.
Specifies CPU feature compatibility masks that override the defaults from the GuestOsDescriptor of the virtual machine's guest OS.
As of vSphere API 6.5 FeatureMask is the recommended method for masking virtual machines with hardware version 9 and above (newer). They can be viewed via featureMask.
Enumerates the set of datastores that this virtual machine is stored on, as well as the URL identification for each of these.
Changes to datastores do not generate property updates on this property. However, when this property is retrieved it returns the current datastore information.
Virtual machine swapfile placement policy.
This will be unset if the virtual machine's swapPlacementSupported capability is false. If swapPlacementSupported is true, the default policy is "inherit".
See also VirtualMachineConfigInfoSwapPlacementTypeEnum.
The VirtualMachineBootOptions data object defines the boot-time behavior of a virtual machine.
You can use the delay options to specify a time interval during which you can enter the virtual machine BIOS setup. These options provide a solution for the situation that occurs when the console attaches to the virtual machine after the boot sequence has passed the BIOS setup entry point.
FaultToleranceConfigInfo is a data object type containing Fault Tolerance settings for this virtual machine.
role, instanceUuids and configPaths contain information about the whole fault tolerance group.
The ReplicationConfigSpec object type encapsulates the replication configuration parameters for a virtual machine.
It consists of two parts: 1) a set of virtual machine-wide replication properties; 2) a set of properties per replicated virtual disk. ReplicationSetting is passed as an argument for initial replication configuration (@see vim.HbrManager#enableReplication) as well as for re-configuration of a replicated VM's properties (@see vim.HbrManager#reconfigureReplication).
Indicates whether user-configured virtual asserts will be triggered during virtual machine replay.
Indicates whether changed block tracking for this VM's disks is active.
Information about firmware type for this Virtual Machine.
Possible values are described in GuestOsDescriptorFirmwareTypeEnum When creating a new VM: - If vim.vm.FlagInfo.vbsEnabled is set to true and this property is set to bios, error is returned. - If this property is unset and vim.vm.FlagInfo.vbsEnabled is set to true, this property is set to efi.
Indicates the maximum number of active remote display connections that the virtual machine will support.
Indicates whether the guest operating system will logout any active sessions whenever there are no remote display connections open to the virtual machine.
The ManagedByInfo data object contains information about the extension responsible for the life-cycle of the entity.

Property to indicate PMem HA failover configuration.
- When set to TRUE, VMs configured to use PMem will be failed over to other hosts by HA, but the data in NVDIMM is not persistent. - When set to FALSE, VMs configured to use PMem will not be failed over to other hosts by HA. Property is currently only applicable to VMs with NVDimms and will fail to set True if vPMem disks are present.
Since: vSphere API Release 7.0.2.0
Indicates whether VMXStats Collection is enabled/disabled.
- If TRUE, VMXStats is enabled for the VM and a scoreboard file is created to store stats for various VMX components. - If FALSE, VMXStats is disabled for the VM and there is no scoreboard file created.
Since: vSphere API Release 7.0.3.1
Indicates whether operation notification to applications is enabled/disabled.

Virtual Persistent Memory configuration for the VM.
Since: vSphere API Release 7.0.3.0
The VirtualDeviceGroups data object type contains information about the backing that maps the virtual device onto a physical device for a Vendor Device Group device.
Vendor Device Groups allow third-parties to define collections of devices that must be allocated to a virtual machine as a unit. Typically, this is because the set of devices are related in a some way, e.g. a physical link connects the devices.
Since: vSphere API Release 8.0.0.1
Indicates whether support to add and remove fixed passthrough devices when the VM is running is enabled.
When the virtual machine is powered on, this indicates if support for hot adding and removing fixed passthrough devices was enabled prior to power on. Otherwise, it indicates whether it will be enabled when the VM is powered on. NOTE: When setting this to true, the memory reservation should be equal to the guest memory size or the option to reserve all guest memory should be selected. If unset, the current value is left unchanged.
Since: vSphere API Release 8.0.1.0
