vim.EnvironmentBrowser

This managed object type provides access to the environment that a ComputeResource presents for creating and configuring a virtual machine.The environment consists of three main components:

• The virtual machine configuration options. Each vim.vm.ConfigOption describes the execution environment for a virtual machine, the particular set of virtual hardware that is supported. A ComputeResource might support multiple sets. Access is provided through the configOptionDescriptor property and the
• QueryConfigOption
• operation.
• The supported device targets. Each virtual device specified in the virtual machine needs to be hooked up to a "physical" counterpart. For networks, this means choosing a network name; for a virtual CD-rom this might be an ISO image, etc. The environment browser provides access to the device targets through the
• QueryConfigTarget
• operation.
• Storage locations and files. A selection of locations where the virtual machine files can be stored, and the possibility to browse for existing virtual disks and ISO images. The datastore browser, provided by the datastoreBrowser property, provides access to the contents of one or more datastores. The items in a datastore are files that contain configuration, virtual disk, and the other data associated with a virtual machine.
• The capabilities supported by the ComputeResource to which the virtual machine belongs.

Attributes

datastoreBrowser (vim.host.DatastoreBrowser):

privilege: System.View

DatastoreBrowser to browse datastores that are available on this entity.

Methods

QueryConfigOptionDescriptor():

The list of ConfigOption keys available on this entity.

Privilege:

System.View

Args:

Returns:

vim.vm.ConfigOptionDescriptor:

QueryConfigOption(key, host):

Query for a specific virtual machine configuration option (the ConfigOption).If the EnvironmentBrowser is from a ComputeResource or ClusterComputeResource, the key or host, or both arguments can be used to return the required config options. If a key is specified, then the ConfigOption corresponding to that key value is returned. If a host is specified, then the default ConfigOption for that host is returned. If key and host both are specified, the ConfigOption corresponding to the given key for that host is returned. If neither is specified, then the default ConfigOption for this environment browser is returned. Typically, the default contains the options for the most recent virtual hardware supported.If the EnvironmentBrowser is from a VirtualMachine neither a host nor a key should be specified.

Privilege:

System.View

Args:

key (str, optional):

The key found in the VirtualMachineConfigOptionDescriptor, obtained by invoking the QueryConfigOptionDescriptor operation.

host (vim.HostSystem, optional):

The host whose ConfigOption is requested.

Returns:

vim.vm.ConfigOption:

Returns the ConfigOption object. If invoked on a cluster with no hosts, or if the ConfigOption with given key is not found for the given host, null is returned.

Raises:

vmodl.fault.InvalidArgument:

if any of the following is true:

• An invalid key is passed.
• An invalid host is passed.
• A key or host is specified, when the command is invoked from the environment browser of a virtual machine.

QueryConfigTarget(host):

Queries for information about a specific target, a "physical" device that can be used to back virtual devices. The ConfigTarget that is returned specifies the set of values that can be used in the device backings to connect the virtual machine to physical (or logical) host devices.If the EnvironmentBrowser is from a ComputeResource or ClusterComputeResource, the host argument can be used to return the ConfigTarget provided by a particular host in the compute resource or cluster. If host is specified and the EnvironmentBrowser is from a ComputeResource or ClusterComputeResource, then the union of all the devices is returned and the vim.vm.TargetInfo.configurationTag field indicates how widely the device is available across the compute resource or cluster.If the EnvironmentBrowser is from a VirtualMachine a host should not be specified.

Privilege:

System.View

Args:

host (vim.HostSystem, optional):

If specified, the host whose default BackingInfo is requested.

Returns:

vim.vm.ConfigTarget:

Returns the ConfigTarget object. If invoked on a cluster with no hosts, null is returned.

Raises:

vmodl.fault.InvalidArgument:

if an invalid host is specified , or a host is given when the EnvironmentBrowser is from a virtual machine.

QueryTargetCapabilities(host):

Queries for information on the capabilities supported by the ComputeResource associated with the EnvironmentBrowser.If the EnvironmentBrowser is from a ComputeResource or ClusterComputeResource, the host argument can be used to return the capabilities associated with a specific host in the compute resource or cluster. If the host argument is not specified and the EnvironmentBrowser is from a ComputeResource or ClusterComputeResource, then the intersection of the capabilities supported by all the hosts in the cluster is returned. If the EnvironmentBrowser is from a VirtualMachine, the compute resource associated with the virtual machine will be queried for its capabilities.If the EnvironmentBrowser is from a VirtualMachine a host should not be specified. since: vSphere API 4.0

Privilege:

System.View

Args:

host (vim.HostSystem, optional):

If specified, the host whose capabilities are requested.

Returns:

vim.host.Capability:

Returns the set of capabilities supported by the ComputeResource associated with the EnvironmentBrowser. If invoked on a cluster with no hosts, null is returned.

Raises:

vmodl.fault.InvalidArgument:

if an invalid host is specified , or a host is given when the EnvironmentBrowser is from a virtual machine.
