8 VBoxManage bandwidthgroup Sets the bandwidth group to use for the given device see chapter 5.8, Limiting bandwidth for disk images, page 80. forceunmount For a virtual DVD or floppy drive only, this forcibly unmounts the DVD/CD/Floppy or mounts a new DVD/CD/Floppy even if the previous one is locked down by the guest for reading. Again, see chapter 5.9, CD/DVD support, page 81 for details. When “iscsi” is used with the --medium parameter for iSCSI support – see chapter 5.10, iSCSI servers, page 82 –, additional parameters must or can be used: server The host name or IP address of the iSCSI target required. target Target name string. This is determined by the iSCSI target and used to identify the storage resource required. port TCP/IP port number of the iSCSI service on the target (optional). lun Logical Unit Number of the target resource (optional). Often, this value is zero. username, password Username and password for target authentication, if required (optional). Note: Currently, username and password are stored without encryption (i.e. in clear text) in the XML machine configuration file. intnet If specified, connect to the iSCSI target via Internal Networking. This needs further con- figuration which is described in chapter 9.7.3, Access iSCSI targets via Internal Networking, page 144. 8.17 VBoxManage storagectl This command attaches/modifies/removes a storage controller. After this, virtual media can be attached to the controller with the storageattach command (see the next section). The syntax is as follows: VBoxManage storagectl uuid|vmname --name name [--add ide/sata/scsi/floppy] [--controller LsiLogic/BusLogic/IntelAhci/PIIX3/ PIIX4/ICH6/I8207] [--sataideemulation1-4 1-30] [--sataportcount 1-30] [--hostiocache on|off] [--remove] where the parameters mean: uuid|vmname The VM UUID or VM Name. Mandatory. name Name of the storage controller. Mandatory. add Define the type of the system bus to which the storage controller must be connected. controller Allows to choose the type of chipset being emulated for the given storage controller. sataideemulation This specifies which SATA ports should operate in IDE emulation mode. As explained in chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, SAS, page 71, by default, this is the case for SATA ports 1-4 with this command, you can map four IDE channels to any of the 30 supported SATA ports. 121
