with a different SCSI adapter so the same operating system can be booted both
natively and inside a virtual machine, but this approach is not supported by VMware.
For details on some of the key issues involved, see
Information on Using SCSI Raw Disks on page
Before You Create the Virtual Machine Configuration
You must create a separate configuration for each guest operating system. Allow read
and write access to the partitions used by that operating system only.
1. Before starting, if you are running a Windows guest operating system you should
read Setting Up Hardware Profiles in Virtual Machines on page
boot the guest operating system natively on the computer and create a
hardware profile for the virtual machine before proceeding.
2. Check to see what SCSI ID is set for the drive you plan to use in the virtual
machine.
3. Make certain that in addition to any SCSI drivers you have configured for the
host, you have also installed the driver for a Mylex® (BusLogic) BT/KT-958
compatible host bus adapter. Drivers for BusLogic controllers are available from
the LSI Logic Web site — www.lsilogic.com. Search the site for Mylex BusLogic
BT/KT-958.
The BusLogic driver needs to be installed in the profile for the guest operating
system.
Note: To use SCSI devices in a Windows XP or Windows Server 2003 virtual
machine, you need a special SCSI driver available from the download section of
the VMware Web site at www.vmware.com/download.
4. Check operating system partition mounts. Be sure the existing raw disk
partitions that you plan to configure the virtual machine to use are not mounted
by the Linux host.
Caution: A raw disk partition should not be used (mounted) simultaneously by
the host and the guest operating system. Because each operating system is
unaware of the other, data corruption may occur if both operating systems read
or write to the same partition. It is critical that the virtual machine not be allowed
to modify any partition mounted under the Linux host or in use by another
virtual machine. To safeguard against this problem, be sure the partition you use
for the virtual machine is not mounted under the Linux host.
5. Set the device group membership or device ownership. The master raw disk
devices must be readable and writable by the user who runs VMware
Workstation. On most distributions, the raw devices (such as /dev/hda and
