Hello, i've some remarks!
2007/5/3, Marc Patino Gómez <mpatino@xxxxxxxxxxxx>:
Hi again,
this is the config of xen in my Debian Etch:
/etc/xen/xend-config
(network-script network-bridge-wrapper)
(vif-script vif-bridge)
(dom0-min-mem 196)
(dom0-cpus 0)
(vncpasswd '')
---------------------------------------------------------------------------
/etc/xen/scripts/network-bridge-wrapper
/etc/xen/scripts/network-bridge start bridge=xenbr0 vifnum=0
/usr/sbin/brctl addbr xenbr1
/sbin/ifconfig xenbr1 up
----------------------------------------------------------------------------
the domu (Firewall)
/etc/xen/firewall-config.sxp
name="firewall"
kernel="/boot/vmlinuz-
2.6.16.33-xenU-x86_64"
root="/dev/hda1"
cpu=3
memory=256
disk=['file:/xen1/firewall.img,hda1,w']
vif=[
'mac=00:16:3e:70:21:02,bridge=xenbr0,vifname=firewall.eth0','mac=00:16:3e:70:32:02,bridge=xenbr1,vifname=
firewall.eth1'
]
dhcp="off"
ip="XX.XX.XX.XX"
netmask="255.255.255.0"
gateway="XX.XX.XX.XX"
In my mind, there is a problem here, because you define one ip="
XX.XX.XX.XX" but you define two vif ...
So where this ip is allocated? vifname=firewall or vifname=firewall.eth1?
hostname="firewall.domain.com"
extra="3"
>on_reboot = 'restart'
on_crash = 'restart'
-------------------------------------------------------------------------------
in this domU (the firewall) I have a bridge between eth1 and eth0, you
can do in CentOS way (inside the domain) ;)
here is the config file of a domu behind the FW:
/etc/xen/domu-config.sxp
name="domu"
kernel="/boot/vmlinuz-2.6.16.33-xenU-x86_64"
root="/dev/hda1"
cpu=3
memory=92
disk=['file:/xen1/domu.img,hda1,w']
vif=[ 'bridge=xenbrFW , vifname=domu.eth0' ]
dhcp="off"
ip="XX.XX.XX.XX"
Here it 's good ! One ip for one vif !
netmask="255.255.255.0"
gateway="XX.XX.XX.XX"
hostname="domu.domain.com"
extra="3"
on_reboot = 'restart'
on_crash = 'restart'
