# cat /var/run/cloud/i-2-5-VM.log i-2-5-VM,5,192.168.30.101,36,1bb8f16bea8fcff2fa927946160a9d0e,27 I can edit this file and change the ip to 192.168.30.123,but the ip will come back to 192.168.30.101 after the vm restarting. ------------------ Original ------------------ From: ""<jayapalreddy.ur...@citrix.com>; Date: Thu, Jun 27, 2013 06:09 PM To: "<users@cloudstack.apache.org>"<users@cloudstack.apache.org>; Subject: Re: How can I allocate a specific IP when I create an instance.
