Disk Drive Requirements for Host Systems
Host systems must meet certain disk drive requirements. Guest operating systems can reside on physical
disk partitions or in virtual disk files.
Table 1-1. Disk Drive Requirements for Host Systems
Drive Type Requirements
Hard disk nIDE, SATA, SCSI and NVMe hard drives are supported.
nAt least 1 GB free disk space is recommended for each guest operating system and
the application software used with it. If you use a default setup, the actual disk space
needs are approximately the same as those for installing and running the guest
operating system and applications on a physical computer.
nFor basic installation, 1.5 GB free disk space is required on Windows and Linux. You
can delete the installer after the installation is complete to reclaim disk space.
Optical CD-ROM and DVD nIDE, SATA, and SCSI optical drives are supported.
nCD-ROM and DVD drives are supported.
nISO disk image files are supported.
Floppy Virtual machines can connect to disk drives on the host computer. Floppy disk image
files are also supported.
Solid-State Drives
If your host machine has a physical solid-state drive (SSD), the host informs guest operating systems
they are running on an SSD.
This allows the guest operating systems to optimize behavior. How the virtual machines recognize SSD
and use this information depends on the guest operating system and the disk type of the virtual disk
(SCSI, SATA, IDE, or NVMe).
nOn Windows 8, Windows 10, Ubuntu, and Red Hat Enterprise Linux virtual machines, all drive types
can report their virtual disks as SSD drives.
Note
nNVMe virtual hard disks are natively supported for Windows 8.1 and later.
nTo create a new a virtual machine with a Windows 7 or Windows 2008 R2 guest operating system
using NVMe as the virtual hard disk, apply the appropriate Windows hot fix. See https://
support.microsoft.com/en-us/kb/2990941.
nSeveral Linux operating systems support NVMe while others do not. Check with the operating
system vendor.
nOn Windows 7 virtual machines, only IDE and SATA virtual disks can report their virtual disks as SSD.
SCSI virtual disks only report as SSD when used as a system drive in a virtual machine, or as a
mechanical drive when used as a data drive inside a virtual machine.
Use the virtual machine operating system to verify your virtual machine is using SSD as its virtual disk.
