I am using a centos template which I had imported from ovirt-image-repository. Whenever I make a VM from this template and configure its initial run section and run it for the first time, everything goes well.  As long as I reboot the server, the VM lost its network configuration (IP, gateway, dns) Then I have to put these parameters again manually. In addition, when I shut down the VM and change its name, the same problem happens again.  This actually causes me pretty much long downtime in order to configure the parameters again.

Your help is highly appreciated.

Best Regards
