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:

Well I thought that I should go the other way. So I did this:
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=""
Okay Now I exported my /rhel5/Dump via NFS. Here's cat /etc/exports
/rhel5/Dump 10.1.1.0/255.255.255.0(rw,sync,no_root_squash)
For the sake of convience I am also posting my /rhel5/Dump/ks.cfg and /etc/dhcpd.conf
cat /etc/dhcpd.conf

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
inet addr:10.1.1.1 Bcast: 10.1.1.255 Mask:255.255.255.0

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.

That means it has created the distro and profile part. Is that perfect or something is missing.
