Setting Screen Colors in a Virtual Machine

Setting Screen Colors in a Virtual Machine

The number of screen colors available inside a virtual machine depends on the screen color setting of the host computer.

On a Windows host, all guests support

  • The number of colors set on the host at the time the guest operating system was started
  • 256 colors (8-bit mode)
  • In some cases, 16 colors (4-bit mode)

On a Linux host, all guests support

  • The same number of colors as set on the host

If you run a virtual machine set for a greater number of colors than your host computer is using, you can encounter various problems. In some cases, for example, the colors in the guest will not be correct. In others, the virtual machine will not be able to use a graphical interface.

In such a case, you can either increase the number of colors available on the host or decrease the number of colors used in the guest.

Changing Screen Colors on the Host

Changing Screen Colors on the Host

If you choose to change the color settings on your host computer, you should first shut down the guest operating system, power off the virtual machine and close VMware Workstation.

Follow standard procedures for changing the color settings on your host computer, then restart VMware Workstation and the virtual machine.

Changing Screen Colors in the Guest

Changing Screen Colors in the Guest

If you choose to change the color settings in the guest operating system, the approach depends on the combination of host and guest you are using.

Windows Hosts

Windows Hosts

Follow the normal process for changing screen colors in your guest operating system. In a Windows guest, the Display Properties control panel offers only settings that are supported.

Linux Hosts

Linux Hosts

A Windows guest running on a Linux host adjusts automatically to the number of colors supported on the host computer. You do not need to take any special steps.

In a Linux or FreeBSD guest, you must change the color depth before you start the X server.
