networking issue for beginners

Mathias Diehl
Hi List,
 
sorry for bothering you with this issue again - but I don't understand the networking stuff at all.....
 
 
However - I managed to build my custom kernels (dom0 with LVM, domFW as priviledged domain to be my firewall and a domU kernel for all my guests).
 
Also I understood that testing is the release to choose becauseI would like to use personalised bridges. (btw, how do I patch files as http://xenbits.xensource.com/xen-unstable.hg?cmd=changeset;node=95f84e37c90d573dd01cc29db5b81ffb5f86f84a didn't work for as I learned to patch...) 
 
 
I hide the 2nd pci devices of my machine from dom0 and attached them to my FW domain
 
lspci in dom0 broght:
 
0000:02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 03)
0000:02:09.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 03)
 
So I modified menu.lst as:
 
title   Xen 3.0 / XenLinux 2.6
kernel  /xen-3.0.gz dom0_mem=262144 physdev_dom0_hide=(02:09.1)
module  /vmlinuz-2.6-xen root=/dev/md2 ro console=tty0
module  /initrd.2.6.12.6-xen.img
 
ifconfig in dom0:

my domU (ppriviledged firewall) config looks like:
# Kernel image file.
kernel = "/boot/vmlinuz-2.6.12.6-xen0-FW"
 
# Initial memory allocation (in megabytes) for the new domain.
memory = 64
 
# A name for your domain. All domains must have different names.
name = "Firewall"

pci = [ '02,09,1' ]
 
vif = [
'mac=ff:fe:00:00:00:01, ip=192.168.100.130, bridge=isp0, vifname=isp0.0',
'mac=ff:fe:00:00:00:02, ip=192.168.100.131, bridge=LAN, vifname=LAN0.0',
'mac=ff:fe:00:00:00:03, ip=192.168.100.132, bridge=DMZ, vifname=DMZ0.0' ]
 
disk = [ 'file:/opt/xen/domains/xen1.img,sda1,w', 'file:/opt/xen/domains/xen1.swap,sda2,w' ]
 
Well - fire up my firewall leads to:
Error: Error creating domain: (38, 'Function not implemented')
and xend-debug.log shows:

I guess I missed a few things....
 
How does xen know, that there are bridges called isp0, LAN and DMZ?
Anything about dummy devices that I forgott?
 
 
Any help would be highly appreciated...
 
thanx
 
Mat
