Ok, I was able to do this successfully. Thanks! It definitely wasn't
obvious from the README.CD, though I should have noticed the
Makefile in the xeno-clone directory. I was basically
messing around in the xenolinux-2.4.22 subdirectory, like
it was a "regular" kernel build.
Now, I'm back at the original problem, which is the same as
for the image.gz and xenoimage.gz from the 1.0 CD image:
- I'm able to boot image.gz via Grub (I renamed image.gz to xenimage.gz):
root (hd0,0)
kernel /xenimage.gz dom0_mem=512000 ser_baud=115000 noht
module /xenolinux.gz root=/dev/sda2 ro console=/dev/tty0 DOMID=0
- It looks like the kernel loads successfully, including
SCSI & network drivers
- There is a message about "guest OS address is 0x0c000000"
then my system reboots. Unfortunately, I cannot catch the
exact message because it's gone too quickly.
I'm thinking either something is missing (like an initrd) or
it's looking for programs in /bin or /usr/bin that were not
installed (the "make install" in xeno-clone makes some binaries,
but just leaves them in the install/bin directories).
I'm motivated to try to solve this problem, so I don't need
to buy Virtuozzo ;-) So, I hope you are able to provide
some guidance. I'll try to help you tune the documentation,
at the same time....
My application, BTW, is Grid services deployment (I'm co-chair
of one of the working groups at http://www.gridforum.org).
