Appendix B: Virtual media

Virtual media and USB 2.0 constraints

The virtual media feature of ServSelect IP VM appliance enables you to connect to the USB port of an attached computer. With this feature, a user located at the appliance or using the remote software can access a local USB storage device, such as a USB CD drive, diskette drive, or flash drive, from an attached computer.

The USB VM SAM module is a composite device that addresses four functions: keyboard, mouse, CD drive, and mass storage device. The CD drive and mass storage device will be present on the target device whether or not a virtual media session is mapped. If a media device is not mapped, it is shown without media present. When a virtual media device is mapped to the target device, the target device will be notified that media has been inserted. When the media device is unmapped, the target device will be notified that the media was removed. Therefore, the USB virtual device is not disconnected from the target device.

The USB VM SAM presents the keyboard and mouse as a composite USB 2.0 device. Therefore the BIOS must support composite USB 2.0 human interface device (HID). If the BIOS of the connected computer does not support this type of device, the keyboard and mouse might not work until the operating system loads USB 2.0 device drivers. If this occurs, there might be a BIOS update provided by the computer manufacturer that will provide BIOS support for a USB 2.0 connected keyboard and mouse.

Booting a computer using virtual memory

In many cases the virtual media feature can boot an attached computer from a device attached to the USB port on the appliance. Most computers with a USB port can use virtual media; however, limitations in some USB media devices and the BIOS of some computers might prevent the computer from booting from a USB device attached to the ServSelect IP VM appliance.

Booting from a virtual USB device is dependant on the target device supporting booting from an external composite USB device. It also requires a CD of the operating system that supports external USB 2.0 booting. The following is a partial list of operating systems that support booting from an external USB 2.0 device:

Windows Server 2003

Windows XP

Windows 2000 Server with Service Pack 4 (SP4) or later

To determine if your computer can be booted from virtual media, complete the following steps:

1.Connect a USB CD drive to the ServSelect IP VM appliance with an operating sys- tem installation CD that is bootable and map it to the target device. Reboot the target device to determine if it will boot from this attached CD drive. The BIOS might need to be set to boot from an external USB device.

2.If the target device will not boot, connect the USB CD drive to a USB port on the tar- get device and reboot the target device. If the target device successfully boots from the CD drive, the BIOS is not supporting booting from a composite USB 2.0 device. Check the support Web site from the target device manufacturer to determine if a later BIOS is available that might support booting from a composite USB 2.0 device. If so, update the BIOS and retry.
