[CentOS] KVM clone

[Nikos Gatsis - Qbit]

Hello everybody.

I have a simple question.

If I clone an existing KVM image of win server with static IP, the clone 
will have the same IP?


It's probably stupid question, but I want to be sure.

I have a full updated centos 7 box.

Thank you in advance.

Nikos.

It totally depends on how you have assigned the address in Windows.  If
you manually assigned the IP address via Windows, then yes, the new one
will have the same Windows License and the same IP address.

If you assigned a static IP via DHCP (so Windows is set to DHCP, and you
control the static IP address via your DHCP Server) .. you could modify
the MAC Address in the KVM image config file and it would boot with a
different address that you can control.  It would still have the same
Windows License though.

Yes, have done it a few times.  If you need it to have a different IP 
address/name/license then bring up a new definition without a NIC, login via 
virt-manager.  For the IP address, search the registry for the current IP 
address and change the appropriate entries.  Use standard Windows utilities to 
change the description/name.  For the license, search for "Product" and select 
"View your Product ID", in that dialog there should be an option to change the 
product key.  Once done add the same NIC as the other definition had and 
restart.  This has worked all but once for me.  The one time it didn't, Windows 
discerned a network problem (IP address) and provided a way to fix it.

I remember that for a cloned win system the SID should be also changed.
