Data Object Description

The ConfigSpec data object type encapsulates configuration settings when creating or reconfiguring a virtual machine. To support incremental changes, these properties are all optional.

Properties

Name Type Description
alternateGuestName*xsd:string

Full name for guest, if guestId is specified as other or other-64.

Reconfigure privilege: VirtualMachine.Config.Settings

Since VI API 2.5
annotation*xsd:string

User-provided description of the virtual machine. Because this property is optional in the virtual machine configuration, it is necessary to pass an explicit empty string in a ConfigSpec object to remove an annotation that is already present in the VirtualMachineConfigInfo for a virtual machine.

Reconfigure privilege: VirtualMachine.Config.Rename

bootOptions*VirtualMachineBootOptions

Settings that control the boot behavior of the virtual machine. These settings take effect during the next power-on of the virtual machine.

Reconfigure privilege: VirtualMachine.Config.Settings

Since VI API 2.5
changeTrackingEnabled*xsd:boolean

Setting to control enabling/disabling changed block tracking for the virtual disks of this VM. This may only be set if the changeTrackingSupported capability is true for this virtual machine. Any change to this property will take effect the next time the virtual machine powers on, resumes from a suspended state, performs a snapshot create/delete/revert operation or migrates while powered on.

Reconfigure privilege: VirtualMachine.Config.ChangeTracking (also required when setting this property while creating a virtual machine)

Since vSphere API 4.0
changeVersion*xsd:string

If specified, the changes are only applied if the current changeVersion matches the specified changeVersion. This field can be used to guard against updates that have happened between when configInfo is read and when it is applied.

For more information about how configurations are uniquely identified, see changeVersion.

consolePreferences*VirtualMachineConsolePreferences

Legacy console viewer preferences that are used with power operations. For example, power on.

Reconfigure privilege: VirtualMachine.Config.Settings

  • Network.Assign if if setting the "backing" property of a VirtualEthernetCard device.

extraConfig*OptionValue[]

Additional configuration information for the virtual machine. This describes a set of modifications to the additional options. An option is removed if the key is present but the value is not set or the value is an empty string. Otherwise, the key is set to the new value.

Configuration keys that would conflict with parameters that are explicitly configurable through other fields in the ConfigSpec object are silently ignored.

Reconfigure privilege: VirtualMachine.Config.AdvancedConfig (also required when setting this property while creating a virtual machine)

files*VirtualMachineFileInfo

Information about virtual machine files.

Reconfigure privilege: VirtualMachine.Config.Settings

flags*VirtualMachineFlagInfo

Additional flags for a virtual machine.

Reconfigure privilege: VirtualMachine.Config.Settings

ftInfo*FaultToleranceConfigInfo

Since vSphere API 4.0
guestId*xsd:string

Short guest operating system identifier.

Reconfigure privilege: VirtualMachine.Config.Settings

instanceUuid*xsd:string

VirtualCenter-specific 128-bit UUID of a virtual machine, represented as a hexadecimal string. This identifier is used by VirtalCenter to uniquely identify all virtual machine instances in the Virtual Infrastructure environment, including those that may share the same SMBIOS UUID.

Normally, this property is not set by a client, allowing the Virtual Infrastructure environment to assign or change it when VirtualCenter detects an identifier conflict between virtual machines. This identifier can be modified even when a virtual machine is powered on. Clients can specify that vCenter Server reassign a new identifier by a providing an empty string. Reassigning the identifer is not allowed for Fault Tolerance virtual machines.

Reconfigure privilege: VirtualMachine.Config.Settings

Since vSphere API 4.0
locationId*xsd:string

128-bit hash based on the virtual machine's configuration file location and the UUID of the host assigned to run the virtual machine.

Normally, this property is not set by a client, allowing the Virtual Infrastructure environment to assign a location ID when the virtual machine is created. However, if the virtual machine's configuration file has been manually moved, it may be desirable to clear this property, setting it to an empty string, so the property is regenerated.

Reconfigure privilege: VirtualMachine.Config.Settings

memoryAffinity*VirtualMachineAffinityInfo

Affinity settings for memory.

Reconfigure privilege: VirtualMachine.Config.Resource

memoryAllocation*ResourceAllocationInfo

Resource limits for memory.

Reconfigure privilege: VirtualMachine.Config.Resource

memoryHotAddEnabled*xsd:boolean

Indicates whether or not memory can be added to the virtual machine while it is running. This attribute can only be set when the virtual machine is powered-off.

Reconfigure privilege: VirtualMachine.Config.Memory

Since vSphere API 4.0
memoryMB*xsd:long

Size of a virtual machine's memory, in MB.

Reconfigure privilege: VirtualMachine.Config.Memory

name*xsd:string

Display name of the virtual machine.

Any % (percent) character used in this name parameter must be escaped, unless it is used to start an escape sequence. Clients may also escape any other characters in this name parameter. Snapshots of virtual machines that have spaces in their names and are associated with ESX 2.x servers are not supported. Therefore, if you want the option to take snapshots of this virtual machine and you are associating it with an ESX 2.x server, do not use spaces in the name.

Reconfigure privilege: VirtualMachine.Config.Rename

networkShaper*VirtualMachineNetworkShaperInfo

Resource limits for network.

Reconfigure privilege: VirtualMachine.Config.Resource

npivDesiredNodeWwns*xsd:short

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

Since vSphere API 4.0
npivDesiredPortWwns*xsd:short

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

Since vSphere API 4.0
npivNodeWorldWideName*xsd:long[]

The NPIV node WWN to be assigned to a virtual machine. This property should only be used or set when the value of npivWorldWideNameOp property is "set". Otherwise, an InvalidVmConfig fault will be thrown. If the specified node WWN is currently being used by another virtual machine, a VmWwnConflict fault will be thrown.

For detail description on WWN, see npivNodeWorldWideName.

Reconfigure privilege: VirtualMachine.Config.Settings.

Since VI API 2.5
npivOnNonRdmDisks*xsd:boolean

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.

Since vSphere API 4.0
npivPortWorldWideName*xsd:long[]

The NPIV port WWN to be assigned to a virtual machine. This property should only be used or set when the value of npivWorldWideNameOp property is "set". Otherwise, an InvalidVmConfig fault will be thrown. If the specified port WWN is currently being used by another virtual machine, a VmWwnConflict fault will be thrown.

For detail description on WWN, see npivPortWorldWideName.

Reconfigure privilege: VirtualMachine.Config.Settings.

Since VI API 2.5
npivTemporaryDisabled*xsd:boolean

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.

Since vSphere API 4.0
npivWorldWideNameOp*xsd:string

The flag to indicate what type of NPIV WWN operation is going to be performed on the virtual machine. If unset, it indicates no change to existing NPIV WWN assignment (or not assigned) in the virtual machine.

Reconfigure privilege: VirtualMachine.Config.Settings.
See NpivWwnOp

Since VI API 2.5
npivWorldWideNameType*xsd:string

This property is used internally in the communication between the VirtualCenter server and ESX Server to indicate the source for npivNodeWorldWideName and npivPortWorldWideName when npivWorldWideNameOp is "set". This property should only be set by the VirtualCenter server.

If this property is set in a call to a VirtualCenter server, an InvalidVmConfig fault will always be thrown. In a call to an ESX Server host, an InvalidVmConfig fault will be thrown if the value of npivWorldWideNameOp is not set to "set".

Reconfigure privilege: VirtualMachine.Config.Settings.

Since VI API 2.5
numCPUs*xsd:int

Number of virtual processors in a virtual machine.

Reconfigure privilege: VirtualMachine.Config.CpuCount

powerOpInfo*VirtualMachineDefaultPowerOpInfo

Configuration for default power operations.

Reconfigure privilege: VirtualMachine.Config.Settings

swapPlacement*xsd:string

Virtual machine swapfile placement policy. This may only be set if the swapPlacementSupported capability is true for this virtual machine. Any change to this policy will take effect the next time the virtual machine powers on, resumes from a suspended state, or migrates while powered on.

Reconfigure privilege: VirtualMachine.Config.SwapPlacement (also required when setting this property while creating a virtual machine)


See VirtualMachineConfigInfoSwapPlacementType

Since VI API 2.5
tools*ToolsConfigInfo
