In order to network cloned VDS with CentOS, what needs to be unique besides IP on each machine?

Question

CentOS

When cloning Windows, I unified MAC address, internal network IP, and "Computer name on the network"
When cloning machines with CentOS, in addition to the MAC address and IP of the internal network, will I need to change something?
So that there are no conflicts.

Answer 1

not to change addresses - people came up with dhcp. There remains only the poppy address, which is generally determined not by the system, but by the hypervisor. And when cloning a machine, the normal hypervisor gives a new poppy to the machine.
To work properly - in the network config (/etc/sysconfig/network-scripts/ifcfg-eth0) the poppy should not be specified and clear /etc/udev/rules.d/70-persistent.net.rules (something like this the file is called , it specifies the device name for each defined network). Those. poppy address is also not necessary to care.
The hostname remains, but this is not a required parameter. In extreme cases, it can also be given through dhcp.
So I don't see any conflicts in centos cloning at all.
And in the case of Windows - all the same reasoning, only you need to change the SID of the machine. But here sysprep will help)
