[Xen-users] DomU network backend issue

[Matthias Wolf <matze.wolf@xxxxxxx>]

Hi,

i am asking myself if there is anybody out there who has a running network
backend domU to which other domU's are connected.

XEN Version:    3.0.2
Kernel Version: 2.6.16.16


The firewall domU is configured as privileged guest with all backend and
frontend drivers compiled into the kernel.

########
[Firewall domU]
name = "firewall"
hostname = "firewall"
kernel = "/boot/vmlinuz-2.6-domU-firewall"

memory = 320
cpus = "0-1"

pci = [ '01:0a.0', '02:09.0' ]
netif = 1

disk = ['file:/mnt/xenimages/gentoo_firewall.xen,sda1,w',
        'file:/mnt/xenimages/gentoo_firewall_swap.xen,sda2,w']
root = "/dev/sda1 ro"

extra = "gentoo=nodevfs"
#########


The domU is configured as non privileged guest with all frontend drivers.

#########
[domU]
name = "test"
hostname = "test"
kernel = "/boot/vmlinuz-2.6-domU"

memory = 320
cpus = "0-1"

vif = [ 'backend=firewall' ]
disk = ['file:/mnt/xenimages/gentoo_test.xen,sda1,w',                           
        'file:/mnt/xenimages/gentoo_test_swap.xen,sda2,w']
root = "/dev/sda1 ro"

extra = "gentoo=nodevfs"
#########

As result i get this:
# Error: Device 0 (vif) could not be connected. Hotplug scripts not working.


Now there are several questions:

1.) Does this really work with 'netif' or is this just a placebo?

2.) If it should work, where is the problem with the hotplug scripts?
    In the dom0? In the firewall domU?

3.) What else do i need on the firewall domU?

Regards
Matthias
