There are some unique IDs to be aware of when cloning or moving VMs around:
- hard disk UUID
If you simply copy/paste a .vdi file, and try to use it on the same machine, you'll get notified about conflicting UUIDs. To fix this, either 1) use 'clonevdi' to make the copy in the first place, or 2) after the fact, use 'setvdiuuid' to generate a new UUID.
- network MAC address
When moving a VM from one machine to the other, if you manually recreate the settings, instead of moving the .vbox file over, you may have issues because the MAC addresses are different. You can fix this by copying the MAC addrseses over (or just use the same .vbox file).
