Virtual Blade Configuration Mode Commands


To configure virtual blades on a WAE device, use the virtual-blade global configuration command. To disable a virtual blade, use the no form of this command.

virtual-blade virtual-blade-number

no virtual-blade virtual-blade-number

Syntax Description

virtual-blade-number

Number of the virtual blade that you want to configure. The range of valid values depends on the number of virtual blades that your WAE or WAVE appliance can support.


Defaults

No default behavior or values.

Command Modes

global configuration

Device Modes

application-accelerator

Usage Guidelines

Use the virtual-blade command to configure virtual blades on your WAE. This command initiates the virtual blade configuration mode as indicated by the (config-vb) prompt.

Within virtual blade configuration mode, you can use the various commands (device, disk, interface, and so on) to define the resource parameters for the virtual blade. To return to global configuration mode, enter the exit command.

Examples

The following example shows how to edit virtual blade 2 and put your WAE into virtual blade configuration mode:

WAE(config)# virtual-blade 2
WAE(config-vb)# 

The following example shows that the prompt changes to (config-vb) to indicate virtual blade mode.

WAE(config-vb)# description This-is-my-virtual-blade-description
WAE(config-vb)# exit
WAE(config)#

(config-vb) boot

To configure the boot image location and source for a virtual blade, use the boot virtual blade configuration command.

boot {cd-image {cd-rom | disk location} | fd-image disk location | from {cd-rom | disk}}

Syntax Description

cd-image

Specifies the location of the boot CD-ROM image for the virtual blade. This image can be located on a CD in the WAE CD-ROM drive or an ISO file located on the WAE hard drive (for example, /local1/vbs/windows_2003.iso).

cd-rom

Specifies that the location is a CD-ROM drive.

disk location

Specifies a location on the WAE hard drive.

fd-image

Specifies the location of the boot floppy disk image for the virtual blade. This image file must be located on the WAE hard drive (for example, /local1/vbs/fdimage).

from

Specifies the source from which the virtual blade will boot. The boot source can be a CD image (defined by the boot cd-image command) or a floppy disk image.

disk

Specifies that the virtual blade boots from the file image defined by the boot fd-image command.


Defaults

No default behavior or values.

Command Modes

virtual blade configuration mode

Device Modes

application-accelerator

Usage Guidelines

The floppy disk image and bootable CD-ROM image must be located in the /local1/vbs directory. The path used with the boot cd-image disk and boot fd-image disk commands must be /local/1vbs/filename. The CD-ROM image can be used to boot the operating system running on the virtual blade. The floppy disk image reserves resources for an emulated floppy disk drive on the virtual blade.

Examples

The following example shows how to configure the CD-ROM ISO boot file location and the boot source for virtual blade 2:

WAE(config)# virtual-blade 2
WAE(config-vb)# boot cd-image disk /local1/vbs/windows_2003.iso
WAE(config-vb)# boot from cd-rom

The following example shows how to configure virtual blade 1 to boot from a CD-ROM located in the WAE optical drive:

WAE(config)# virtual-blade 1
WAE(config-vb)# boot cd-image cd-rom
WAE(config-vb)# boot from cd-rom

To enter a description for a virtual blade on your WAE, use the description virtual blade configuration command.

description description-text

Syntax Description

description-text

Text to briefly describe the virtual blade.


Defaults

No default behavior or values.

Command Modes

virtual blade configuration mode

Device Modes

To set the device emulation parameters used by the virtual blade on your WAE, use the device virtual blade configuration command.

device {cpu {qemu64 | qemu32} | nic {rtl8139 | E1000 | virtio} | disk {IDE | virtio}}

Syntax Description

cpu

Specifies the CPU emulation to be used on the virtual blade.

qemu64

Specifies a 64-bit processor emulator.

qemu32

Specifies a 32-bit processor emulator

nic

Specifies the network interface card emulation to be used on the virtual blade.

rtl8139

Specifies a Realtek network card emulator.

virtio

Specifies a generic NIC emulator optimized for virtual machines.

disk

Specifies the type of hard drive emulation to be used on the virtual blade.

IDE

Specifies an IDE (ATA) type disk emulator.

virtio

Specifies a generic disk controller emulator optimized for virtual machines.


Defaults

The default values are as follows:

device cpu qemu64

device nic rtl8139

device disk IDE

Command Modes

virtual blade configuration mode

Device Modes

application-accelerator

Examples

The following example shows how to set the device emulation parameters for virtual blade 2. The CPU emulator is set to qemu64, the NIC emulator is set to rtl8139, and the disk type emulator is set to IDE.

WAE(config)# virtual-blade 2
WAE(config-vb)# device cpu qemu64
WAE(config-vb)# device nic rtl8139
WAE(config-vb)# device disk IDE
