Hi, there,
I am watching this thread with interest.
Marc, can you repeat the actual steps you do to set up Linux guest VMs,
especially the ones using 2.4 kernels.
I have tried similar steps you mentioned, apart from the cp -pr /lib/modules
into the guest OS disk, but when I start up the guest VM, it complains
If you are going to "full virtualitzed" a linux box you don't need to
copy the kernel's modules, you will use the unmodified old OS kernel
ones, and the old kernel (of course).
"boot loader didn't return any data!"
Have you copy the full HD? or only the partition?
It looks like something is missing to turn the root copied file system to be
bootable
as a guest VM.
Thanks.
Peter
Good luck Peter,
Marc

Hi,
rsync works great on production enviroments, I had paravirtualized some servers
with these method:
rsync -ave ssh --exclude=/proc --exclude=/sys --exclude=/dev (if you are using
udev) root@runingserver:/ /mnt/newserverimage/
after this:
mkdir /mnt/newserverimages/proc
mkdir /mnt/newserverimages/sys
mkdir /mnt/newserverimages/dev
review your fstab, and copy the kernel modules:
cp -pr /lib/modules/2.6.16-xenU /mnt/newserverimages/lib/modules/
more or less .... this is the way
Also I have full virtualitzed some old GNU/Linux boxes with kernels 2.4, I used
GNU/Linux live CD on the old box and dd utility:
dd if=/dev/hda | ssh root@xxxxxxxxxxxxxxxxx "/bin/dd
of=/dev/vg00/newvserver"
I hope it will be helpfull
Marc
