that last check also needs the " && (!sharedvm)" check in the new version, because VMs with only shared disks are allowed to be linked clones (the disks are not moved anyway in that case).

also "s/parrent/parent/" ;) the old outdated comment in front of the if should probably also be removed, the new one describes the situation better imho
