About VMware Linked Clones
A linked clone is a copy of a virtual machine that continually shares virtual disks with the parent virtual machine. This conserves disk space, and allows multiple virtual machines to use the same software installation.
A linked clone is made from a snapshot of the parent. All files available on the parent at the moment of the snapshot continue to remain available to the linked clone. Ongoing changes to the virtual disk of the parent do not affect the linked clone, and changes to the disk of the linked clone do not affect the parent. A linked clone must have access to the parent. Without access to the parent, a linked clone is disabled.
If a VM remains out of all the VMs being deleted from linked clone VMs, then all the VMs are brought back to the original size of the parent VM.
If a VM is migrated to some other host and datastore, it retains the original size of the parent VM.
