Load iPXE in DomU of Xen

[ccheng]

Hi All,

Is there a way to chainload ipxe.lkrn in the DomU of Xen?

I saw a supporting request posted in the ipxe developing mailing two years ago. And I did the same test by letting pvgrub to load ipxe.lkrn and get the expected following error.

xc: error: panic: xc_dom_bzimageloader.c:655: xc_dom_probe_bzimage_kernel: boot protocol too old (0207): Invalid kernel
xc: error: panic: xc_dom_core.c:621: xc_dom_find_loader: no loader found: Invalid kernel

That supporting request also pointed out that iPXE needs to be built as a bzImage instead of a zImage and a new driver will be needed for Xen virtual network interface (netfront). Is there anything else we need to consider if we want to load ipxe.lkrn in DomU?

Thanks in advance!
