----- Original Message ----- | Most likely you're running into what is essentially a "Missing boot | device driver." Commonly a "7B" blue screen on Windows. | | While iPXE can speak HTTP just fine and translate an ISO file as a | physical disk to BIOS, because HTTP-sourced SAN devices don't have a | BFT mechanism like iSCSI does (the iBFT), iPXE can't pass information | about what the "boot" device is or how to access it to the operating | system once it's online. Presumably, after the CentOS live CD you're | using loads the kernel and its drivers, it still needs to source more | files from that CD to finish the boot process. iPXE is non-functional | at that point, and since the OS can't find the disk, it crashes. | | Any Live CD that boots *completely* into a RAM disk will work very, | very well with this boot method though. I use it to boot Windows PE | 3, and on a moderately fast computer, it's online in 10 seconds or so. | | Perhaps someone else on the list could suggest a Live CD for CentOS | that boots from a RAM disk device? | | Best Regards, | Andrew Bobulsky
But, the raw ISO image does boot on a system with no hard disk indicating that it is booting into a full RAM disk. The only difference is that it's a CD drive attached to my KVM host. This would then seem to indicate that the sanboot of the ISO image is not presenting as a physical disk of any sort to the underlying operating system and thereby dying.
