VirtualMachineValidation Class

Attempts to determine whether or not the application is running in a known virtual machine guest environment. See the VirtualMachineValidationVirtualMachineType enumeration for a list of supported hypervisors.

Properties

	Name	Description
	IsVirtual	Gets whether the system is running on a virtual machine guest environment. (This property should only be referenced after calling the Validate method once.)
	LastError	Gets or sets the last error encountered in this object. (Inherited from SystemValidation.)
	Type	Gets the type of virtual machine guest environment on which the system is running. (This property should only be referenced after calling the Validate method once.)

Methods

	Name	Description
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)
	Validate	Determines if the system is running on a virtual machine. (Overrides SystemValidationValidate.)

Remarks

Caution
This class can only detect supported hypervisors, which are documented in the VirtualMachineValidationVirtualMachineType enumeration.

Caution
It is not possible to guarantee the detection of a virtual machine guest environment, as many hypervisors have settings (which may or may not even be officially supported or documented by the manufacturer of the hypervisor) which allow the hypervisor to change its behavior in ways that could make it difficult to detect. Despite this, this class has been designed to avoid this kind of weakness as much as reasonably possible. Additionally, using these settings for day-to-day application use is typically problematic, which makes it unlikely to encounter this kind of behavior (as users would not typically use such undocumented, unsupported, problematic settings).
