    Some other host already uses address...


      I just create an Oracle Enterprise Linux virtual machine on a Xen Server, and this weird thing happened. I tried to assign a private address ( and this error message appears: Error message: Some other host already uses address

      I decided to make an arping as follows:

      arping -I eth0 -c 3

      ..and the resulting MAC address belongs to our main router (a Cisco 2900).

      So, the thing is, no matter which (private) IP I use as an argument in the previous command, the answer is the same MAC, and the error appears every time I try to setup ANY IP address on the Linux Box.

      When I use a public IP address, it throws no error whatsoever.

      Any ideas?

      Thank you very much in advance.
