Deleting Devices

You can delete a virtual device that you do not need any more in your virtual machine using the --device-del option of the prlctl set command. The options responsible for removing particular devices are listed in the following table:

Option	Description
`hdd`	Deletes the specified hard disk drive from the virtual machine. Note: SATA disks can be removed from running and stopped virtual machines while IDE and SCSI disks—from stopped virtual machines only.
`cdrom`	Deletes the specified CD/DVD-ROM drive from the virtual machine.
`net`	Deletes the specified network adapter from the virtual machine.
`fdd`	Deletes the floppy disk drive from the virtual machine.
`serial`	Deletes the specified serial port from the virtual machine.
`parallel`	Deletes the specified parallel port from the virtual machine.
`sound`	Deletes the sound device from the virtual machine.
`usb`	Deletes the USB controller from the virtual machine.

As a rule deleting a virtual device involves performing two operations:

Finding out the name of the device to be deleted.
Deleting the device from the virtual machine.

Finding Out the Device Name

To remove a virtual device, you need to specify its name when running the prlctl set command. If you do not know the device name, you can use the prlctl list command to learn it. For example, to obtain the list of virtual devices in the MyVM virtual machine, run this command:

# prlctl list --info MyVM

...

Hardware:

cpu 2 VT-x accl=high mode=32

memory 256Mb

video 46Mb

fdd0 (+) real='/dev/fd0' state=disconnected

hdd0 (+) ide:0 image='/var/parallels/MyVM.pvm/harddisk.hdd' 27Mb

hdd1 (+) scsi:0 image='/var/parallels/MyVM.pvm/harddisk1.hdd' 32768Mb

cdrom0 (+) ide:1 real='Default CD/DVD-ROM'

parallel0 (+) real='/dev/lp0'

usb (+)

net0 (+) type=bridged iface='eth1' mac=001C4201CED0

...

All virtual devices currently available to the virtual machine are listed under Hardware. In our case the MyVM virtual machine has the following devices: 2 CPUs, main memory, video memory, a floppy disk drive, 2 hard disk drives, a CD/DVD-ROM drive, a parallel port, a USB controller, and a network card.

Deleting a Virtual Device

Once you know the virtual device name, you can remove it from your virtual machine. For example, you can execute the following command to remove the virtual disk hdd1 from the MyVM virtual machine:

# prlctl set MyVM --device-del hdd1

Remove the hdd1 device.

The VM has been successfully configured.

When deleting virtual machine devices, keep in mind the following:

If you do not want to permanently delete a virtual device, you can temporarily disconnect if from the virtual machine using the --disable option.
Detailed information on all options that can be used with prlctl set when deleting a device is given in the Virtuozzo 6 Command Line Reference Guide.
