Yes, snapshots (these are like rollback-points on Windows) can be 
deleted. But they *must* be deleted with the "prlctl" tool.

See: 
https://docs.openvz.org/openvz_command_line_reference.webhelp/_prlctl_snapshot_snapshot_list_snapshot_switch_snapshot_delete_2.html

In my experience it is best to first get a tree view of the snapshot 
structure, as there might be several children snapshots that are tied 
into one or more parents. And you have to delete them from youngest to 
oldest.

You can list the snapshots in a tree view like this:

#> prlctl snapshot-list <VM_name> -t

And then delete them from youngest first like this:

#> prlctl snapshot-delete <VM_name> --id <snapshot_ID>

That should do it.
