Not that great. Is there something I'm missing?


You'd have to kexec the hypervisor and give it a module of the vmlinuz file, in the same way that grub does it. I've no idea if kexec has that functionality though.

All right, something like that gets me farther:

kexec -l xen-3.1 --module="vmlinuz-2.6.18-xen-uncomp initrd-2.6.18-xenU.img"

Obviously, the module entry is wrong.

# kexec -l xen-3.1 --module="vmlinuz-2.6.18-xen netloop.nloopbacks=16 other_params..." --module="initrd-2.6.18-xenU.img" --append="noapic dom0_mem=128M"
# kexec -e

Ends with:

(XEN) not enough memory to stash the DOM0 kernel image.

Hmm.
