[Xen-users] xen and wireless domUs

["john maclean" <jayeola@xxxxxxxxx>]

Hi chaps,
host = laptop
dom0 = debian testing
domU = various
problem = providing wireless to my domUs
references = 
http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Virtualization-en-US/ch-virt-laptop-configurations.html

That ref has been good so far in that a CentOS instance has got an IP
with dummy0.

host machine:-
cat /etc/issue && cat /etc/network/interfaces
Debian GNU/Linux 4.0 \n \l

# -*- sh -*-
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth1
iface eth1 inet dhcp
iface eth2 inet dhcp
iface eth3 inet dhcp
iface eth4 inet dhcp

iface dummy0 inet static
address 10.1.1.1
netmask 255.255.255.0
broadcast 10.0.0.255
# arp=yes
# peerdns yes

a CentOS instance
cat /etc/issue && cat /etc/sysconfig/network-scripts/ifcfg-dummy && ifconfig
CentOS release 4.5 (Final)
Kernel \r on an \m

DEVICE=dummy0
BOOTPROTO=none
ONBOOT=no
TYPE=Wireless
# NETWORKING=yes
HOSTNAME=centos4.localdomain
GATEWAY=10.1.1.1
IPADDR=10.1.1.10
NETMASK=255.255.255.0

ifconfig
dummy0    Link encap:Ethernet  HWaddr 7E:40:FE:5C:67:F0
         inet addr:10.1.1.10  Bcast:10.1.1.255  Mask:255.255.255.0
         UP BROADCAST RUNNING NOARP  MTU:1500  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:17 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:0 (0.0 b)  TX bytes:4995 (4.8 KiB)

soooooo close, as at least I have an address ;). Point is that there
is an /etc/rc.foo/bah script in the reference above that's very Redhat
specific. Has any one something similar on a Debian system? I know (or
think) that the next step is to allow the domUs access to the outside
world but I'm not sure how this is done.
