What other identifiers would you need to alter in a cloned virtual machine to be sure it was unique? What might happen if these changes are not done?

Following identifiers needs to be altered in cloned VM.

Explanation:

When we clone the VM, we have to make sure that Cloned VM should have unique system information and network addresses in and out of guest OS.

If UUID’s of all cloned VM's are different then DHCP will get separate ip addresses for those. Suppose if the IP addresses are static or If the IP address was hardcoded then it has to be changed to new IP address manually. If this is not done then it will cause duplicate IP’s and will cause networking issues.

When Cloned VM is created then the ethernet port has to be chosen correctly to make sure that LAN networking is correct.

You should specify the disk capacity. If you choose disk capacity as single file then it will create one vmdk file. So, specify the correct disk capacity, If you did not choose the disk file as single file then you may end up having multiple .vmdk files. So in that case you need to rename the pointers of copy of vmdk files.

Rename the Second Disk Drive. For example : You may find two VM files with VM Copy.vmdk, So you have to rename second disk to VM Copy-1.vmdk or any other name.

The cloned VM copies the parent virtual machine and it also includes the VM name. To avoid problems caused by having VM's with duplicate names on the network, give the VM in the cloned VM a unique name.

You have to make sure that hostnames are different as well. Hostname resolution will lead to conflict if its same on both VM's.
