Virtual Hard Drive

Adding a Hard Drive

--device-add hdd [--image <image_name>] [--type <expand | plain>] [--size <n>] [--split]

[--iface <ide | scsi | sata>] [--position <n>]

[--subtype <buslogic | lsi-spi | lsi-sas>]

[--online-compact <on | off>]

Modify a Hard Drive

--device-set <hdd_name> [--image <image_name>] [--type <expand | plain>]

[--size <n>] [--split] [--iface <ide | scsi | sata>] [--position <n>]

[--subtype <buslogic | lsi-spi | lsi-sas>] [--online-compact <on | off>]


hdd_name: The name of the virtual hard drive to modify (--device-set command only). Virtual hard drives are named using the hddN 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 --info command.

--image: specifies the name of the file to be used for emulating the VM virtual disk drive. If this option is omitted, a new file is created inside the directory storing all VM-related configuration files and assigned the name of harddiskN.hdd.

--type: specifies the type of the virtual disk from one of the following:

  • expand (default): virtual disks of this type are small initially and grow in size as you add data to it.

  • plain: virtual disks of this type have a fixed size from the moment of their creation.

--size: hard disk size, in megabytes.

--split: splits the hard disk into 2GB pieces.

--iface: virtual hard disk interface type: ide, scsi, or sata.

--position: the SCSI / IDE / SATA device identifier to be used for the disk drive. Allowed ranges:

  • 0-3 for IDE disk drives

  • 0-6 for SCSI disk drives

  • 0-5 for SATA disk drives

--subtype: virtual hard disk subtype: buslogic, lsi-spi, lsi-sas.

--online-compact: enables or disables virtual hard disk online compact mode.
