Console Operating System and VMkernel

Ethernet card assigned to the VMkernel is given the name vmnic0 and the two SCSI

cards assigned to the VMkernel are given the names vmhba0 and vmhba1.

Note: You only need to load the Adaptec VMkernel module once, even though two

Adaptec SCSI cards are assigned to the VMkernel.

The VMkernel can also share SCSI adapters with the console operating system, rather

than exclusively controlling them. The installation process allows you to specify SCSI

adapters that are shared and load the device module appropriately. However, if you

wish to control the sharing explicitly, assign the SCSI device to the console operating

system during the installation process. Then load the VMkernel SCSI module using the

following syntax:

vmkload_mod -d bus:slot \

/usr/lib/vmware/vmkmod/aic7xxx.o vmhba

Note: This command should be entered on a single line. Do not type the backslash.

To obtain the bus and slot (also known as device or cardnum) information, examine

/proc/pci, output from the scanpci command, or both.

Note: The device must be correctly assigned to the console operating system.

Devices assigned exclusively to the VMkernel during the installation process no longer

appear in /proc/pci.

After you load a VMkernel device module, an entry appears in /proc/vmware/net

or /proc/vmware/scsi. For example, when e100.o is loaded as described

above, the entry /proc/vmware/net/vmnic0 appears, indicating there is one

EEPro card controlled by the VMkernel and available as vmnic0 to the virtual

machines. See Configuring Virtual Machines on page 181 for information on how to

configure virtual machines to use VMkernel devices.

Other Information about VMkernel Modules

The only non-device VMkernel module available in this release of VMware ESX Server

is the nfshaper module, which provides support for network filtering, as described

in Network Bandwidth Management on page 253. Load nfshaper using the

following syntax.

vmkload_mod /usr/lib/vmware/vmkmod/nfshaper.o nfshaper

VMkernel modules must be reloaded each time the VMkernel is loaded (as described

in Loading VMkernel Device Modules on page 174). If you have configured your

system to load the VMkernel automatically on each reboot, you can have the modules

loaded automatically as well by adding entries to the file

/etc/vmware/vmkmodule.conf. The vmkmodule.conf file is read only if it
