Re: [Xen-users] the simplest example to start

[Massimo Canonico <mex@xxxxxxxxxxxx>]

Alexander,
thanks for your reply.

Maybe my problem could be summarized with this question: how can I run a 
VM by using ttylinux image (or other minimal linux distro)?
In many website, they propose to download an ttylinux image and then use 
this config file:
kernel="/boot/kernel/xen-3.0.2/vmlinuz-2.6-xenU"
memory=64
name="ttylinux"
disk=['file:/boot/ttylinux-5.0/rootfs,sda1,w']
dhcp="dhcp"
root="/dev/sda1 ro"
extra="4"

Unfortunately, this it is not enough (ehre can I find the 
vmlinux-2.6-xenU required?).
So, please, if anyone has a complete example (img + kernel + ramdisk + 
config file) I would be very happy to see xen able to run a very minimal 
linux image.
Thanks in advance,
 Massimo
