CHAPTER 3 Using the VMware Management Interface to Manage Your Virtual Machines

1. In the Hardware page, under SCSI Controller, click Edit. The SCSI Controller page
appears.
2. In the Virtual Device list, select the SCSI controller driver which you want the
virtual machine to use. Choose vmxbuslogic or vmxlsilogic.
Caution: Before you select a different driver, make sure you installed the driver in
the guest operating system first; otherwise, the guest cannot boot. To switch to
the vmxlsilogic driver, see Configuring a Virtual Machine to Use the LSI
Logic SCSI Adapter on page 59.
3. In the Bus Sharing list, select how you want the virtual machine to share its bus.
Choose one of the following:
• Physical — to share disks with virtual machines on any server.
• Virtual — to share disks with virtual machines on the same server.
• None — to prevent sharing of disks with other virtual machines.
4. Click OK to save your changes and close the window.
Configuring a Virtual Machine’s Virtual Disks
When you configure an existing virtual disk, you can change its disk mode. You can
also change the virtual disk a virtual machine uses or create a new virtual disk for the
virtual machine.
ESX Server can use disks in four different modes.
• Persistent: Disks in persistent mode behave exactly like conventional disk drives
on a computer. All writes to a disk in persistent mode are written out
permanently to the disk as soon as the guest operating system writes the data.
• Nonpersistent: All changes to a disk in nonpersistent mode are discarded when
a virtual machine session is powered off.
