Configuring and Maintaining Virtual Hard Disks
You can use Player to configure virtual hard disk storage for virtual machines.
A virtual disk is a file or set of files that appears as a physical disk drive to a guest operating system. The files
can be on the host system or on a remote computer. When you configure a virtual machine to use a virtual
disk, you can install a new operating system onto the virtual disk without repartitioning a physical disk or
rebooting the host.
The New Virtual Machine wizard creates a virtual machine that has one disk drive. You can modify virtual
machine settings to add more disk drives to a virtual machine, remove disk drives from a virtual machine, and
change certain settings for the existing disk drives.

Configuring a Virtual Hard Disk on page 77
You can configure virtual hard disks as IDE 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.
n
Compact a Virtual Hard Disk on page 80
Compacting a virtual hard disk reclaims unused space in the virtual disk. If a disk has empty space, this
process reduces the amount of space the virtual disk occupies on the host drive.
n
Expand a Virtual Hard Disk on page 80
You can add storage space to a virtual machine by expanding its virtual hard disk.
n
Defragment a Virtual Hard Disk on page 81
Like physical disk drives, virtual hard disks can become fragmented. Defragmenting disks rearranges
files, programs, and unused space on the virtual hard disk so that programs run faster and files open
more quickly. Defragmenting does not reclaim unused space on a virtual hard disk.
n
Remove a Virtual Hard Disk from a Virtual Machine on page 81
Removing a virtual hard disk disconnects it from a virtual machine. It does not delete files from the host
file system.
n
Using Lock Files to Prevent Consistency Problems on Virtual Hard Disks on page 82
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.
n
Moving a Virtual Hard Disk to a New Location on page 82
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 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 or SCSI virtual hard disk can be stored on an IDE hard disk or on a SCSI hard
disk. They can also be stored on other types of fast-access storage media.
