I hope you don't cry now, but I'm not using any bootloader :) I really can't see the use for it. Actually I have *two* kernels now, but the only thing my users see is an linux-2.6 as kernel in their config. > (As an aside, Xen really does seem intent on thinking that you need a > real block device to boot from in a few other areas.

Oh they are doing: kernel initrd-hey-here-are-the-iscsi-tools-lets-switch-rootfs Instead the nfsway: kernel-lets-find-a-nice-iscsi-machine Not only the best way, the only way you can *safely* hide your storage from the domU's.
