Remove a Virtual Hard Disk from a Virtual Machine on page 86

Removing a virtual hard disk disconnects it from a virtual machine. It does not delete files from the

host file system.

Using Lock Files to Prevent Consistency Problems on Virtual Hard Disks on page 86

A running virtual machine creates lock files to prevent consistency problems on virtual hard disks.

Without locks, multiple virtual machines might read and write to the disk, causing data corruption.

Moving a Virtual Hard Disk to a New Location on page 86

A key advantage of virtual hard disks is their portability. Because the virtual hard disks are stored as

files on the host system or a remote computer, you can move them easily to a new location on the

same computer or to a different computer.

Configuring a Virtual Hard Disk

You can configure virtual hard disks as IDE or SATA disks for any guest operating system. You can also set

up a virtual hard disk as a SCSI disk for any guest operating system that has a driver for the LSI Logic or

BusLogic SCSI adapter. You determine which SCSI adapter to use when you create a virtual machine.

The files that make up an IDE, SATA, or SCSI virtual hard disk can be stored on an IDE hard disk, SATA

hard disk, or on a SCSI hard disk. They can also be stored on other types of fast-access storage media.

To use SCSI hard disks in a 32-bit Windows XP virtual machine, you must download a special SCSI driver

from the VMware Web site. Follow the instructions on the Web site to use the driver with a fresh installation

of Windows XP.

Growing and Allocating Virtual Disk Storage Space

IDE and SCSI virtual hard disks can be up to 8TB. Depending on the size of the virtual hard disk and the

host operating system, Player creates one or more files to hold each virtual disk.

Virtual hard disk files include information such as the operating system, program files, and data files.

Virtual disk files have a .vmdk extension.

By default, the actual files that the virtual hard disk uses start small and grow to their maximum size as

needed. The main advantage of this approach is the smaller file size. Smaller files require less storage space

and are easier to move to a new location, but it takes longer to write data to a disk configured in this way.

You can also configure virtual hard disks so that all of the disk space is allocated when the virtual disk is

created. This approach provides enhanced performance and is useful if you are running performance-

sensitive applications in the virtual machine.

Regardless of whether you allocate all disk space in advance, you can configure the virtual hard disk to use

a set of files limited to 2GB per file. Use this option if you plan to move the virtual hard disk to a file system

that does not support files larger than 2GB.

Add a New Virtual Hard Disk to a Virtual Machine

To increase storage space, you can add a new virtual hard disk to a virtual machine. You can add up to four

IDE devices and up to 60 SCSI devices. Any of these devices can be a virtual or physical hard disk or DVD

or CD-ROM drive.

Virtual hard disks are stored as files on the host computer or on a network file server. A virtual IDE drive or

SCSI drive can be stored on a physical IDE drive or on a physical SCSI drive.

If you have a Windows NT 4.0 virtual machine that has a SCSI virtual hard disk, you cannot add both an

additional SCSI disk and an IDE disk to the configuration.

As an alternative to adding a new virtual hard disk, you can expand the existing virtual hard disk. See

“Expand a Virtual Hard Disk,” on page 84.
