Finally I got rid of the dhcp problem. But I had to stop my dummy0 virtual network interface in dom0 host and have to bridge my xenbr1 to eth1 (physical wireless device on dom0 host). The installation started without asking me anything (that was real great un-attended installation).
The only thing it asked was when it was about to create the partitions. It asked me whether it should format the whole disk or not. When I pressed Yes it continued. If I want it to not ask this thing what should I do. And one more thing after installation it stop and asked me to press reboot button. If I want it to automatically reboot then what should I do. I guess something %post directive.
Please help. And one more thing, I had to made huge modifications in my kickstart file. So I am posting it once more. Hope it help you guys in getting me:

Hello guys,
I somehow overcome the balloon problem. What I did was I delete the system and profile by
cobbler system remove --name=<system_mac>
cobbler profile remove --name=<profile_name>
And I added again the profile but this time I gave --virt-ram-size=256 (as this was where koan reported warning earlier) and then I created system as I did previously.
Then I ran koan once again (as I did earlier) but now a new problem. It starts the virtual machine and ask me to connect to it via xm console. I did so but it hangs during acquiring ip address from dhcp. After sometime it ask me to give ip address manually I do so ( 10.1.1.45/255.255.255.0 gateway 10.1.1.1) but then it reports error in getting nfs:/10.1.1.1/rhel5/Dump/ks.cfg. I have figured out the problem. But don't know how to resolve it.
It is the same as I mentioned earlier. I have two network interfaces. One is eth1 (wireless device) and other is dummy0 (virtual network interface). All the communication of xen vm's with the xen dom0 is done via a bridge xenbr1 which is mapped to dummy0. And in the dhcpd.conf there is nothing for the subnet 10.1.1.0 and if I do manually (as of now cobbler is managing my dhcpd.con) it reports error and doesn't start dhcpd service. The error is logged into /var/log/messages and it is shown below:

Note: I have my RHEL5 Dump in /rhel5/Dump
cobbler distro add --name=rhel5 --kernel=/rhel5/Dump/images/xen/vmlinuz --initrd=/rhel5/Dump/images/initrd.img
This ran good. Then I did the following:
cobbler profile add --name=redhat5x --distro=rhel5 --kickstart=/rhel5/Dump/ks.cfg --virt-file-size=2 --virt-ram=128
cobbler system add --name=00:16:3E:5F:93:6A --profile=""

I don't know what happened during the ballon but it didn't created the virtual machine I was expecting.
One more thing I would like to through light on is that I have configured a virtual dummy0 network interface which is bridged to xenbr1. Here's my ifconfig(not shown are the xen virtual interfaces):
dummy0 Link encap:Ethernet HWaddr F6:42:E2:23:B6:57

All my xen related network stuff is handled by dummy0 and it is then masqureaded to eth1. I think there is problem with /etc/dhcpd.conf regarding eth1 and dummy0. I am not getting it.
Please through some light.
