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 ( <a href="http://10.1.1.45/255.255.255.0">10.1.1.45/255.255.255.0</a> gateway <a href="http://10.1.1.1">10.1.1.1</a>) 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 <a href="http://10.1.1.0">10.1.1.0</a> 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: Mar 31 10:05:01 server dhcpd: Internet Systems Consortium DHCP Server V3.0.5-RedHat Mar 31 10:05:01 server dhcpd: Copyright 2004-2006 Internet Systems Consortium.
