Hello,

I want to implement a diskless xen hypervisor. The way I suppose it will work 
is xen booted over pxe and
getting iscsi san storage to store vm images.

Is solution like that usable ?
it certainly is.  i believe somebody here did that, but using AoE
instead of iSCSI....

the result is extremely neat, splitting your hardware needs in two
types of boxes: storage boxes, and processor/RAM boxes.  adding extra
storage or processing power means just plugging it in and adding it to
the respective tables. no more software installing!

For now I stick with NFS-root, but there in no reason not to go to
PXE/initrd entirely...


Stefan

I played around with this, too.
But if I make initrd to big. Maybe 128MB, then the System will not boot,
saying something like, not enough memory to boot xen hypervisor.

Anyone had this issue, too?

Cheers,
Alex
