On 64-bit hosts, the maximum amount of memory for each virtual machine is 64GB. On 32-bit hosts, the
maximum amount of memory for each virtual machine is 8GB. You cannot power on virtual machines that are
configured to use more than 8GB of memory on 32-bit hosts. Memory management limitations on 32-bit
operating systems cause virtual machine memory to overcommit, which severely affects system performance.
The total amount of memory that you can assign to all virtual machines running on a single host machine is
limited only by the amount of RAM on the host machine.
You can change the amount of memory available to all virtual machines by modifying Workstation memory
settings.
Selecting the Network Connection Type for a Virtual Machine
When you select a custom configuration, the New Virtual Machine wizard prompts you to configure the
network connection type for the virtual machine.
If you are creating a remote virtual machine, you must select either a custom network or no network connection.
Table 1-6. Network Connection Settings
Setting Description
Use bridged networking Configure a bridged network connection for the virtual machine. With bridged
networking, the virtual machine has direct access to an external Ethernet network. The
virtual machine must have its own IP address on the external network.
If your host system is on a network and you have a separate IP address for your virtual
machine (or can get an IP address from a DHCP server), select this setting. Other
computers on the network can then communicate directly with the virtual machine.
Use network address translation
(NAT)
Configure a NAT connection for the virtual machine. With NAT, the virtual machine
and the host system share a single network identity that is not visible outside the
network.
Select NAT if you do not have a separate IP address for the virtual machine, but you
want to be able to connect to the Internet.
Use host-only networking Configure a host-only network connection for the virtual machine. Host-only
networking provides a network connection between the virtual machine and the host
system, using a virtual network adapter that is visible to the host operating system.
With host-only networking, the virtual machine can communicate only with the host
system and other virtual machines in the host-only network. Select host-only
networking to set up an isolated virtual network.
Do not use a network connection Do not configure a network connection for the virtual machine.
Custom (Windows host) or Named
Network (Linux host)
(Remote virtual machine only) Select a specific virtual network.
See Chapter 5, “Configuring Network Connections,” on page 139 for information about virtual switches,
virtual network adapters, the virtual DHCP server, and the NAT device.
Selecting the I/O Controller Type for a Virtual Machine
When you select a custom configuration, the New Virtual Machine wizard prompts you to select the I/O
controller type for the virtual machine.
Workstation installs an IDE controller and a SCSI controller in the virtual machine. The IDE controller is always
ATAPI. For the SCSI controller, you can choose BusLogic, LSI Logic, or LSI Logic SAS. If you are creating a
remote virtual machine on an ESX host, you can also select a VMware Paravirtual SCSI (PVSCSI) adapter.
BusLogic and LSI Logic adapters have parallel interfaces. The LSI Logic SAS adapter has a serial interface. The
LSI Logic adapter has improved performance and works better with generic SCSI devices. The LSI Logic
adapter is also supported by ESX Server 2.0 and later.
