Hello, I have Xen server 3.1 running. We installed this into our network before I was hired. We also had a Nat''d IP. The ip address of the base system was the public IP. Due to changing business requirements we needed more IPs. Our ISP gave us a block. I had to change the IP structure for the whole company. I had to change the IP''s of the guest VM''s (virtual machine) on Xen. The challenge is this. I cannot change the IP of the Xen base system so I can use the xenserver-client to create new vm and add new ones. It seems it is bridged. How can I change the ip address so I can then use the client to do some updates and add new VM. Or..how can I increase the virtual hard drive space on one of my virtual machines. This is just a short term workaround. The challenge of changing the IP address of the base system which is XEN is proving to be difficult. Any help is greatly appreciated. Long live Xen Thank you, Sonny
