Where is vboxmanage located

These are typically represented by disk images, such as those in VDI format. The location of these files may vary, depending on the host operating system.

See Section 3. By default, each virtual machine has a directory on your host computer where all the files of that machine are stored: the XML settings file, with a. This is called the machine folder. The location of this home directory depends on the conventions of the host operating system, as follows:.

In the machine folder, a settings file: Example VM. In the machine folder, a virtual disk image: Example VM. Once you start working with the VM, additional files are added. You cannot modify this setting while recording is enabled. Specify the absolute path of the webcam on the host operating system, or use its alias, obtained by using the command: VBoxManage list webcams. Note that alias '. The device order is host-specific. The optional settings parameter is a ; delimited list of name-value pairs, enabling configuration of the emulated webcam device.

MaxFramerate: Specifies the highest rate in frames per second, at which video frames are sent to the guest. The default setting is no maximum limit , thus enabling the guest to use all frame rates supported by the host webcam. MaxPayloadTransferSize: Specifies the maximum number of bytes the emulated webcam can send to the guest in one buffer. The default setting is bytes, which is used by some webcams. Higher values can slightly reduce CPU load, if the guest is able to use larger buffers.

Note that higher MaxPayloadTransferSize values may be not supported by some guest operating systems. Specify the absolute path of the webcam on the host, or use its alias obtained from the webcam list command.

Please note the following points, relating to specific host operating systems:. Windows hosts: When the webcam device is detached from the host, the emulated webcam device is automatically detached from the guest. When the webcam device is detached from the host, the emulated webcam device remains attached to the guest and must be manually detached using the VBoxManage controlvm webcam detach command.

Linux hosts: When the webcam is detached from the host, the emulated webcam device is automatically detached from the guest only if the webcam is streaming video.

If the emulated webcam is inactive, it should be manually detached using the VBoxManage controlvm webcam detach command. The output is a list of absolute paths or aliases that were used for attaching the webcams to the VM using the webcam attach command. If the VM has been suspended and the password has been removed, the user needs to resupply the password before the VM can be resumed. This feature is useful in cases where the user does not want the password to be stored in VM memory, and the VM is suspended by a host suspend event.

The DEK is stored encrypted in the medium properties, and is decrypted during VM startup by supplying the encryption password. This command discards the saved state of a virtual machine which is not currently running. This will cause the VM's operating system to restart next time you start it. This is the equivalent of pulling out the power cable on a physical machine, and should be avoided if possible.

If you have a Saved state file. This will change the VM to saved state and when you start it, Oracle VM VirtualBox will attempt to restore it from the saved state file you indicated. This command should only be used in special setups. Optionally, you can request that the image be deleted. You will get appropriate diagnostics that the deletion failed, however the image will become unregistered in any case.

This command attaches, modifies, and removes a storage medium connected to a storage controller that was previously added with the storagectl command. The syntax is as follows:. A number of parameters are commonly required. Some parameters are required only for iSCSI targets. Name of the storage controller. The list of the storage controllers currently attached to a VM can be obtained with VBoxManage showvminfo. The number of the storage controller's port which is to be modified.

Mandatory, unless the storage controller has only a single port. The number of the port's device which is to be modified. Mandatory, unless the storage controller has only a single device per port. Define the type of the drive to which the medium is being attached, detached, or modified.

This argument can only be omitted if the type of medium can be determined from either the medium given with the --medium argument or from a previous medium attachment. For example, because it has been attached to another virtual machine. This medium is then attached to the given device slot. The disk image is then attached to the given device slot. In this case, additional parameters must be given.

These are described below. Others, such as device changes or changes in hard disk device slots, require the VM to be powered off. Defines how this medium behaves with respect to snapshots and write operations.

An optional description that you want to have stored with this medium. This is purely descriptive and not needed for the medium to function correctly. This is an expert option. Inappropriate use can make the medium unusable or lead to broken VM configurations if any other VM is referring to the same media already. The most frequently used variant is --setuuid "" , which assigns a new random UUID to an image. This option is useful for resolving duplicate UUID errors if you duplicated an image using a file copy utility.

This feature is currently experimental, see Section 5. For a virtual DVD drive only, you can configure the behavior for guest-triggered medium eject.

If this is set to on, the eject has only a temporary effect. If the VM is powered off and restarted the originally configured medium will be still in the drive. Enables you to enable the non-rotational flag for virtual hard disks. Some guests, such as Windows 7 or later, treat such disks like SSDs and do not perform disk fragmentation on such media.

Enables the auto-discard feature for a virtual hard disks. The following requirements must be met:. On Windows, occasional defragmentation with defrag. Ext4 supports the -o discard mount flag.

Mac OS X probably requires additional settings. Windows should automatically detect and support SSDs, at least in versions 7, 8, and It is unclear whether Microsoft's implementation of exFAT supports this feature, even though that file system was originally designed for flash. Alternatively, there are other methods to issue trim. For example, the Linux fstrim command, part of the util-linux package. Earlier solutions required a user to zero out unused areas, using zerofree or similar, and to compact the disk.

This is only possible when the VM is offline. Sets the bandwidth group to use for the given device. When iscsi is used with the --medium parameter for iSCSI support, additional parameters must or can be used. See also Section 5. Target name string. This is determined by the iSCSI target and used to identify the storage resource. Logical Unit Number of the target resource. Often, this value is zero. Hex-encoded Logical Unit Number of the target resource.

Username and password, called the initiator secret, for target authentication, if required. Username and password are stored without encryption, in clear text, in the XML machine configuration file if no settings password is provided. When a settings password is specified for the first time, the password is stored in encrypted form.

As an alternative to providing the password on the command line, a reference to a file containing the text can be provided using the passwordfile option.

A gigabit Ethernet adapter that transmits megabits per second Mbps is recommended for the connection to an iSCSI target. Each port on the adapter is identified by a unique IP address. The device can be an end node, such as a storage device, or it can be an intermediate device, such as a network bridge between IP and Fibre Channel devices. Each port on the storage array controller or network bridge is identified by one or more IP addresses. This needs further configuration, see Section 9.

This command attaches, modifies, and removes a storage controller. After this, virtual media can be attached to the controller with the storageattach command. Specifies the type of the system bus to which the storage controller must be connected. Enables a choice of chipset type being emulated for the given storage controller. This specifies the number of ports the storage controller should support.

This command creates, deletes, modifies, and shows bandwidth groups of the given virtual machine. Use the --machinereadable option to produce the same output, but in machine readable format.

Type of the bandwidth group. Two types are supported: disk and network. Specifies the limit for the given bandwidth group. This can be changed while the VM is running.

The default unit is megabytes per second. The unit can be changed by specifying one of the following suffixes: k for kilobits per second, m for megabits per second, g for gigabits per second, K for kilobytes per second, M for megabytes per second, G for gigabytes per second.

The network bandwidth limits apply only to the traffic being sent by virtual machines. The traffic being received by VMs is unlimited. To remove a bandwidth group it must not be referenced by any disks or adapters in the running VM. This command shows information about a medium, notably its size, its size on disk, its type, and the virtual machines which use it.

For compatibility with earlier versions of Oracle VM VirtualBox, the showvdiinfo command is also supported and mapped internally to the showmediuminfo command. The medium must be specified either by its UUID, if the medium is registered, or by its filename. Specifies the differencing image parent, either as a UUID or by the absolute pathname of the file on the host file system. Useful for sharing a base box disk image among several VMs.

Specifies the file format for the output file. The default format is VDI. Specifies any required file format variants for the output file. This is a comma-separated list of variant flags. Not all combinations are supported, and specifying mutually incompatible flags results in an error message. For compatibility with earlier versions of Oracle VM VirtualBox, the createvdi and createhd commands are also supported and mapped internally to the createmedium command. With the modifymedium command, you can change the characteristics of a disk image after it has been created.

For compatibility with earlier versions of Oracle VM VirtualBox, the modifyvdi and modifyhd commands are also supported and mapped internally to the modifymedium command. The disk image to modify must be specified either by its UUID, if the medium is registered, or by its filename. Registered images can be listed using VBoxManage list hdds , see Section 8. A filename must be specified as a valid path, either as an absolute path or as a relative path starting from the current directory.

With the --type argument, you can change the type of an existing image between the normal, immutable, write-through and other modes. For immutable hard disks only, the --autoreset on off option determines whether the disk is automatically reset on every VM startup.

By default, autoreset is on. The --compact option can be used to compact disk images. Compacting removes blocks that only contains zeroes. Using this option will shrink a dynamically allocated image. It will reduce the physical size of the image without affecting the logical size of the virtual disk.

Compaction works both for base images and for differencing images created as part of a snapshot. For this operation to be effective, it is required that free space in the guest system first be zeroed out using a suitable software tool. For Windows guests, you can use the sdelete tool provided by Microsoft. Run sdelete -z in the guest to zero the free disk space, before compressing the virtual disk image. Please note that compacting is currently only available for VDI images.

A similar effect can be achieved by zeroing out free blocks and then cloning the disk to any other dynamically allocated format. You can use this workaround until compacting is also supported for disk formats other than VDI. The --resize x option, where x is the desired new total space in megabytes enables you to change the capacity of an existing image. This adjusts the logical size of a virtual disk without affecting the physical size much. It can only be used to expand, but not shrink, the capacity.

For example, if you originally created a 10 GB disk which is now full, you can use the --resize command to change the capacity to 15 GB 15, MB without having to create a new image and copy all data from within a virtual machine. Note however that this only changes the drive capacity. You will typically next need to use a partition management tool inside the guest to adjust the main partition to fill the drive.

The --resizebyte x option does almost the same thing, except that x is expressed in bytes instead of megabytes. The path can be either relative to the current directory or absolute. The new location is used as is, without any sanity checks. The user is responsible for setting the correct path. This command duplicates a virtual disk, DVD, or floppy medium to a new medium, usually an image file, with a new unique identifier UUID.

The medium to clone as well as the target image must be described either by its UUIDs, if the mediums are registered, or by its filename. Registered images can be listed by VBoxManage list hdds. A filename must be specified as valid path, either as an absolute path or as a relative path starting from the current directory. Set a file format for the output file different from the file format of the input file.

Set a file format variant for the output file. Not all combinations are supported, and specifying inconsistent flags will result in an error message. Perform the clone operation to an already existing destination medium. Only the portion of the source medium which fits into the destination medium is copied.

This means if the destination medium is smaller than the source only a part of it is copied, and if the destination medium is larger than the source the remaining part of the destination medium is unchanged. For compatibility with earlier versions of Oracle VM VirtualBox, the clonevdi and clonehd commands are still supported and mapped internally to the clonemedium command. This command is used to create a DEK encrypted medium or image.

Either specify the absolute pathname of a password file on the host operating system, or - to prompt you for the password on the command line. Always use the --newpasswordid option with this option. Either specify the absolute pathname of a password file on the host operating system, or - to prompt you for the old password on the command line. Use this option to gain access to an encrypted medium or image to either change its password using --newpassword or change its encryption using --cipher.

Use this option to change any existing encryption on the medium or image, or to set up new encryption on it for the first time. This can be chosen by the user, and is used for correct identification when supplying multiple passwords during VM startup. If the user uses the same password when encrypting multiple images and also the same password identifier, the user needs to supply the password only once during VM startup.

This command is used to check the current encryption password on a DEK encrypted medium or image. Select the disk image format to create. Choose a file format variant for the output file. The stdin form of the command forces VBoxManage to read the content of the disk image from standard input. This useful when using the command in a pipe. For compatibility with earlier versions of Oracle VM VirtualBox, the convertdd command is also supported and mapped internally to the convertfromraw command.

These commands enable you to attach and retrieve string data for a virtual machine or for an Oracle VM VirtualBox configuration, by specifying global instead of a virtual machine name. You must specify a keyword as a text string to associate the data with, which you can later use to retrieve it.

This example would associate the string " You could then retrieve the information as follows:. To remove a keyword, the setextradata command must be run without specifying data, only the keyword. This command is used to change global settings which affect the entire Oracle VM VirtualBox installation.

Some of these correspond to the settings in the Preferences dialog in the VirtualBox Manager. The following properties are available:. Specifies the default folder in which virtual machine definitions are kept. If you wish to share these extensions with other hypervisors running at the same time, you must disable this setting.

Doing so has negative performance implications. Specifies which library to use when external authentication has been selected for a particular virtual machine. Specifies which library the web service uses to authenticate users. Selects the path to the autostart database. Selects the global default VM frontend setting. Used when a manual proxy is configured using the manual setting of the proxymode property. Global filters are applied before machine-specific filters, and may be used to prevent devices from being captured by any virtual machine.

Global filters are always applied in a particular order, and only the first filter which fits a device is applied. For example, if the first global filter says to hold, or make available, a particular Kingston memory stick device and the second filter says to ignore all Kingston devices. That particular Kingston memory stick will be available to any machine with the appropriate filter, but no other Kingston device will.

When creating a USB filter using usbfilter add , you must supply three or four mandatory parameters. The index specifies the position in the list at which the filter should be placed.

If there is already a filter at that position, then it and the following ones will be shifted back one place. Otherwise, the new filter will be added onto the end of the list. The target parameter selects the virtual machine that the filter should be attached to or use global to apply it to all virtual machines. For global filters, action says whether to allow VMs access to devices that fit the filter description hold or not to give them access ignore.

In addition, you should specify parameters to filter by. You can find the parameters for devices attached to your system using VBoxManage list usbhost. Finally, you can specify whether the filter should be active. For local filters, whether they are for local devices, remote devices over an RDP connection, or either.

When you modify a USB filter using usbfilter modify , you must specify the filter by index and by target, which is either a virtual machine or global. See the output of VBoxManage list usbfilters to find global filter indexes and VBoxManage showvminfo to find indexes for individual machines. The properties which can be changed are the same as for usbfilter add. To remove a filter, use usbfilter remove and specify the index and the target. The following is a list of the additional usbfilter add and usbfilter modify options, with details of how to use them.

Applies to global filters only. For usbfilter create the default is active. The string representation for an exact match has the form XXXX, where X is the hexadecimal digit, including leading zeroes.

The string representation for an exact match has the form IIFF, where I is the decimal digit of the integer part of the revision, and F is the decimal digit of its fractional part, including leading and trailing zeros.

Note that for interval filters, it is best to use the hexadecimal form, because the revision is stored as a bit packed BCD value. Therefore, the expression int:0xx will match any revision from 1. Applies to VM filters only.

The value is a bit mask where the set bits correspond to the USB interfaces that should be hidden, or masked off. This feature only works on Linux hosts.

The guestproperty commands enable you to get or set properties of a running virtual machine. Guest properties are arbitrary keyword-value string pairs which can be written to and read from by either the guest or the host, so they can be used as a low-volume communication channel for strings, provided that a guest is running and has the Guest Additions installed.

This list will be very limited if the guest's service process cannot be contacted, for example because the VM is not running or the Guest Additions are not installed. The pattern can contain the following wildcard characters:.

For example, " fo? If the property cannot be found, for example because the guest is not running, the following message is shown:. With --flags , you can specify additional behavior. You can combine several flags by separating them with commas. The pattern rules are the same as for the enumerate subcommand. The guestcontrol commands enable control of the guest from the host. The guestcontrol command has two sets of subcommands.

The first set requires guest credentials to be specified, the second does not. The common options for the first set of subcommands are explained in the following list.

Specifies the user name on guest OS under which the process should run. This user name must already exist on the guest OS. If unspecified, the host user name is used.

Specifies the absolute path on guest file system of password file containing the password for the specified user account or password for the specified user account. If both are omitted, empty password is assumed. Specifies the absolute path of the executable on the guest OS file system. Specifies the maximum time, in microseconds, that the executable can run, during which VBoxManage receives its output.

If unspecified, VBoxManage waits indefinitely for the process to end, or an error occurs. Sets, modifies, and unsets environment variables in the environment in which the program will run.

The guest process is created with the standard default guest OS environment. Use this option to modify that default environment. To set, modify, and unset multiple variables, use multiple instances of the --E --putenv option. In the case of --wait-stdout , VBoxManage receives its stdout while the process runs. Does not wait or waits until the guest process ends and receives its exit code, error messages, and flags.

In the case of --wait-stderr , VBoxManage receives its stderr while the process runs. Not yet implemented. Specifies the program name, followed by one or more arguments to pass to the program. On Windows there are certain limitations for graphical applications. See Chapter 14, Known Limitations. Examples of using the guestcontrol run command are as follows:. Note that the double backslashes in the second example are only required on UNIX hosts. For certain commands a user name of an existing user account on the guest must be specified.

Anonymous executions are not supported for security reasons. A user account password, however, is optional and depends on the guest's OS security policy or rules. Asked 9 years, 8 months ago.
