(config-vb) boot
Use the boot from cd-rom option before you have installed a guest OS, to boot from a guest OS installer
CD (a physical CD or an .iso file located in /local1/vbs).
Use the boot from disk option after you have installed a guest OS, to boot from the installed guest OS.
If you specified boot from disk, the cd-image keyword is optional and configures the location of a
CD-ROM image that is made available to the guest OS (but is not used for booting). The CD image can
be changed during operation, by using the virtual-blade n cd eject EXEC command followed by the
virtual-blade n cd disk /local1/vbs/newimage.iso or the virtual-blade n cd cd-rom EXEC command.
The boot from network option requires PXE to be enabled on your network. A DHCP broadcast
message with PXE boot options is sent, and the DHCP server provides the location of files to download
for boot.
Use the boot from network option to install the same version of software to many virtual blades, or to
boot each virtual blade with a complete OS stored and managed in a centralized network location. If you
are network booting to install the guest OS, then you may want to configure the virtual blade to boot
from the disk on subsequent boots. You can do this by modifying the boot from parameter while the
virtual blade is running.
Examples The following example shows how to configure virtual blade 2 to boot from a CD image file (such as a
guest OS installer CD) located on the WAE hard disk:

WAE(config-vb)# boot cd-image disk /local1/vbs/windows_2003.iso
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 from cd-rom
WAE(config-vb)# boot cd-image cd-rom
The following example shows how to configure virtual blade 1 to boot from a previously installed guest
OS installed on the WAE hard disk:
WAE(config)# virtual-blade 1
WAE(config-vb)# boot from disk
The following example shows how to configure virtual blade 1 to boot from a network location:
