Cloning and Rebuilding a VPS
Clone copies a stopped VPS's disk into a brand new guest with its own IP, keeping the same OS, sizing, and SSH key/password. The source VPS must be stopped first so the disk copy is consistent - Virtlix will tell you to stop it if you try otherwise. Go to Virtual Machines → Clone VPS, pick the source, give the clone a name and hostname.
Rebuild goes the other direction: it wipes a VPS's disk and reinstalls the OS from scratch, keeping the same VPS ID, IP, and hostname. Useful when a guest's OS is broken beyond repair but you want to keep the same IP allocation. This is destructive - anything on the existing disk is gone once you confirm it.
Both actions respect the same owner resource-plan and license VPS-limit checks as creating a new VPS from scratch (clone counts as an additional VPS; rebuild doesn't, since the VPS already existed).
