[Xen-users] Unable to communicate with Dom0

[Subhabrata Bhattacharya <xions.microcosm@xxxxxxxxxxxxxx>]

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.
                                                                failed
Setting up interface eth0:                                      done
Setting up interface eth0:                                      done

                                                                failed
----------------------------


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:
