Name

Description

ID

The virtual machine ID.

VM_name

The virtual machine name.

--device-add

Adds a virtual hard disk drive to the virtual machine.

You can connect up to four IDE devices and up to seven SCSI devices to a virtual machine. This includes hard disks and optical disk drives.

--device-set

Modifies the parameters of an existing virtual hard disk.

hdd

Specifies the type of the virtual device to add to the virtual machine (in this instance, a virtual hard disk).

hdd N

The name of the virtual hard disk to modify. Virtual hard disks are named using the hdd N format where N is the drive index number starting from 0 (e.g. hdd0 , hdd1 ). To obtain the list of disk names, use the prlctl list command with the --info option.

--image name

This options is used to create a virtual hard disk using an image file. You have an option of creating a new image file or to use an existing image.

• To use an existing image file, specify its name and path using the name parameter.
• To create a new image file, omit the --image parameter. New image files are created in the virtual machine directory and are automatically named using the harddisk N .hdd format, where N is the disk index number (e.g. harddisk0.hdd , harddisk1.hdd ).

--device name

This option is used to create a virtual hard disk based on a boot camp partition (Mac hosts). The name parameter must contain the boot camp partition name.

--type expand|plain

For image file based virtual disk drives, specified the disk type:

• expand -- expanding disk. The image file is small initially and grows in size as you add data to it. This is the default virtual disk type.
• plain -- plain disk. The image file has a fixed size from the moment it is created (i.e the space is allocated for the drive fully). Plain disks perform faster than expanding disks.

--size number

The size of the virtual hard disk, in megabytes. The default size is 32,000 MB.

--split

Splits the hard disk image file into 2 GB pieces. You should split a virtual disk if it is stored on a file system that cannot support files larger than 2 GB (e.g. FAT16).

--iface ide|scsi

Interface type:

• ide --  IDE drive.
• scsi -  SCSI drive (default).

--position number

The SCSI or IDE device identifier to be used for the virtual disk. The allowed ID ranges are the following:

• for IDE devices: 0:0 , 0:1 , 1:0 , 1:1 ;
• for SCSI device: 0:0 , 1:0 , 2:0 , 3:0 , 4:0 , 5:0 , 6:0 .

You can use one of the following formats for specifying IDs: ID : bus , ID - bus , ID . For example, if you specify 3:0 (or 3-0 or 3) as number for a SCSI drive, the guest OS will see the drive as having ID 3 on SCSI bus 0.

--enable

Enables the specified virtual disk drive. All newly added disk drives are enabled by default (provided the --disable option is omitted).

--disable

Disables the specified virtual disk drive. The disk drive itself is not removed from the virtual machine configuration.
