Hi,

Anybody has experience doing tftpboot (pxeboot) of xen? I do not seem to 
find any hints from googling.

Thanks,
Weikuan

I used to have this working using grub. It is no different from booting
linux using TFTP and Grub, however the problem with Grub is that last
time I looking network driver support for modern cards was limited. In
the end I made things work using an experimental patch which added UNDI
support, where the BIOS supplies the driver for the network card, but
the patch made Grub rather flaky.

There is nothing special about TFTP-booting Xen with Grub, the same
rules apply as when booting Xen from disk with Grub. Find some howto on
TFTP-booting, and adapt it to use Xen instead of e.g. Linux.

Good luck,
Jacob

Search for xen and mboot.c32
e.g.

DEFAULT mboot.c32 xen.gz dom0_mem=258048 --- vmlinuz-2.6.12.5-xen0 ro
console=ttyS0 root=/dev/nfs --- initrd-2.6.12.5-xen0

You could use GRUB (although you have to compile it yourself to enable
networking.  Another option is using mbootpack so it works with every
bootloader.

Many thanks for all the help I have received. I managed to boot it with
Ian's instruction on using mboot.c32. 

mbootpack did not work for me as it complains not able to find multiboot
header. Seems to be a known issue. I will just move ahead from this
then.

Thanks again,
Weikuan

Many thanks for all the help. I managed to boot with Ian's instruction 
on using mboot.c32.

mbootpack did not work for as it complains not able to find multiboot 
header. Guess that is a solved problem. I will just move ahead then.

Thanks again,

Fwiw, I use mboot.c32 too, but am looking at Etherboot's new AoE
support, which works great except on the machine I want it to work on :(
(grub hangs at loading 1.5)

The idea is that as far as the machine is concerned grub and everything
else behave as if it were a real disk, rather than having to remember to
put the kernel updates on the tftp share.
