We have tried to install the Ubuntu 12.04 LTS Server on the XEN Citirx. When we try to boot from the DVD Drive media When We refer to citrix forum we have a similar post for 10.04 "http://community.citrix.com/display/xs/Installing+Ubuntu+Server+10.04+%2832bit+and+64bit%29+LTS/"
When we try the same we get a error of invalid source.
Thanks in advance if some one could help us in this regards
