Hi,
I am able to boot Xen Domain 0 on Linux 2.6.11.10-Xen0 kernel. The
installation is perfect.
But while booting Xen-DomainU [Linux 2.6.11.10-XenU] I recieve these
messages and after booting into the unprevileged domain, I am unable
to ping Domain 0. The reverse is also not possible.
Running local start scripts.
Starting basic firewall: modprobe: could not parse modules.dep
iptables v1.2.11: can''t initialize iptables table `filter'':
iptables
who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Setting up interface eth0: done
Setting up interface eth0: done
Setting default route: route: SIOC[ADD|DEL]RT: Network is unreachable

----------------------------
This is my Domain U configuration.
[root@tux06 xenfs]# cat /etc/xen/tintin
kernel = "/boot/vmlinuz-2.6.11.10-xenU"
memory = 128
name = "tintin"
nics = 1
vif = [''bridge=xen-br0'']
netmask="255.255.255.192"
gateway="172.21.31.129"
ip="172.21.31.171"
hostname="tintin"
root = "/dev/hda5 ro"
disk = [''file:/mnt/xenfs/tintin,hda5,w'']
---------------------
And this is my Domain 0 network configuration:
[root@tux06 xenfs]# ifconfig -a

Hi, could you make a ifconfig -a on the Xen-DomainU and send the output please ? I''ve read somewhere (can''t remember where) a similar problem where network interface was not started on boot.

Re: [Xen-users] Unable to communicate with Dom0
hi, Thanks all of your suugestions.I figured out the problem with iptables. Although I had iptables compiled as kernel objects, still I was facing the problem.I added the virtual interfaces with the bridge which wasn''t added by default.And then a small command did all the magic. $iptables -A FORWARD -m physdev --physdev-in eth0 --physdev-out eth0 -j ACCEPT ---- ~$ubh _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
