ubuntu livecd iso net boot

James: The virtual CD that sanboot gives you access to is only available until the operating system kernel starts. At that point it is no longer available. This is completely normal with most operating systems (except DOS). The OS takes over completely control over the hardware, so you need to tell it again where to find the network resources you want access to (like a mounted ISO). In most cases (unless you're dealing with DOS) it is best to unpack the ISO and boot the kernel/ramdisk directly from iPXE or another boot loader (like grub/syslinux).
