one Newbe again :/

one Newbe again :/

[Darko Hojnik]

Hello List

I have today compiled XEN on an fresh installed Debian GNU Linux Sarge 
on VMware to get my first experients with this Software. Based with the 
Orginalconfigurationfile i have compiled the Kernel 2.6.10-xen0 again to 
ad some Hardwaredrivers and the Filesystem XFS for booting my System.
So i can boot with the new Kernel and after "xend start" are the last 
lines in dmesg

device eth0 entered promiscuous mode
xen-br0: port 1(eth0) entering learning state
xen-br0: topology change detected, propagating
xen-br0: port 1(eth0) entering forwarding state
xen-br0: no IPv6 routers present
Server:~#

Everything seems like to be OK

here my menu.ist
title           Debian GNU/Linux, kernel 2.6.8-2-686-smp
root            (hd0,0)
kernel          /vmlinuz-2.6.8-2-686-smp root=/dev/sda3 ro
initrd          /initrd.img-2.6.8-2-686-smp
savedefault
boot

title          Xen 2.0 / XenLinux 2.6.10

module         /vmlinuz-2.6.10-xen0 root=/dev/sda3 ro console=tty0
savedefault
boot

After part one i tried to create an virtual Machine like the exemple in 
the Doc's, so i have downloaded the file ttylinux-xen.bz2 and create a 
simple config like this

kernel = "/boot/vmlinuz-2.6.10-xen0"
memory = 64
name = "ttylinux-xen"
nics = 1
ip = "192.168.1.100"
disk = ['file:/opt/ttylinux-xen,sda1,1,w']
root = "/dev/sda1 ro"

My Problem, i can not start an virtual machiene and i do not know why. 
Maybe anybody can help me

Server:~# xm create /root/test -c
Using config file "/root/test".
Error: Error creating domain: invalid backend domain

Welcome to the list!

Glad you've got Xen up and running on your hardware.  The problem you're 
seeing appears to be a minor glitch in your configuration.

You've got one field too many for this disk:

> disk = ['file:/opt/ttylinux-xen,sda1,1,w']
                                       ^
---------------------------------------|
    
The extra 1 is confusing the tools into trying to configure a driver domain.  
Change that line to:

disk = ['file:/opt/ttylinux-xen,sda1,w']

And it should work.

HTH,
Mark
