Just to be certain I followed these exact steps, except of course that I
used my own config instead of crab-domU.cfg, including pulling a completely
new clone. It builds and boots just fine, although it won't run with
memory=10 anymore. It now only works from memory=12 up. If you want I can
send you the built kernel in a private mail.
Please do, reply to my private email in the header. If it boots on 12 it
is good enough for me. But I could probably strip it further to make
sure it would fit a smaller memory footprint.
disk = ['cow:/crab/.xen/crab-domU.cfg 30, hda1,w']
disk = ['file:/crab/.xen/crab-domU.cfg, hda1,w']
And this definitely must be wrong.
s/cfg/img :-)
I wonder if there is something else on the system that produces broken
kernels. Bad compiler or mismatched libraries.
I guess I do not need xen installed to compile the kernel, right? Maybe
I should try to ssh to my home machine (which I know is 100% fine) and
compile on that. It it also faster..
But anyways, please send me the binary kernel and the system.map and I
will test it.
Thanks!
