Hi all!

I have a question about networking and haven't been able to find it online. I need to replicate a server installation in a host to be able to test a procedure but the host is on the same network as the servers so I am not being able to create an isolated network on the host because there is an interface in the same range of ip adresses. Is there any way to create this isolated virtual network without it conflicting with the hosts network?

my quick guess is that you have created a copy of the VM with identical MAC addresses for the NIC.
Each NIC on your network needs to have a unique MAC address.

There are a few tools to generate random MAC addresses.
Grab one of these and then just change the mac address in the clone VM.
