Configuring and Running Virtual Machines

182

www.vmware.com

There may also be situations when you want to create virtual machines that are more

complex than you can create using the VMware Management Interface. In these

cases, start with the configuration file template,

/usr/share/doc/vmware/sample.cfg. Copy it to a new file and manually

edit the copy as described in this section.

Using VMkernel Devices

The VMkernel devices — whether shared or not — must be referenced and activated

in the VMware virtual machine’s configuration (.cfg) file, as described in this section.

You must also load a special VMware network driver into the guest operating system,

as described in the section Installing VMware Tools and the Network Driver in the

Guest Operating System on page 73.

Ethernet

The Ethernet section of the configuration file is in this format:

ethernet0.present = TRUE

ethernet0.connectionType = monitor_dev

ethernet0.virtualDev = vmxnet

ethernet0.devName = vmnic0

ethernet0.exclusive = TRUE

In this configuration, ethernet0.connectionType = monitor_dev and

ethernet0.virtualDev = vmxnet specify that the virtual machine’s

Ethernet uses the VMkernel high-performance network device.

ethernet0.devName = vnmic0 specifies that the virtual network device

corresponds to the first network device activated by the command

vmkload_mod .../vmkernel .../XXX.o vmnic. See VMkernel Module

Loader on page 174 for details on vmkload_mod. The line

ethernet0.exclusive = TRUE makes the networking more efficient if only

one virtual machine is using the network card. You should remove this line if more

than one virtual machine needs to use the card.

VMFS Virtual SCSI Disks

VMware ESX Server supports a simple file system known as VMFS (VMware ESX Server

File System) on physical SCSI disks and partitions to make it easy to allocate space for a

disk image. VMFS allows many disk images to be stored on one large physical SCSI disk

or partition. The VMware Management Interface automatically creates VMFS file

systems and VMFS files as you configure your system and create virtual machines.

However, VMFS files can also be created and managed via the vmkfstools(1)

command. An example configuration that uses a disk image allocated in a VMFS is:

1 2 ... 177 178 179 180 181 182 183 184 185 186 187 ... 285 286
