如果在install新的zone或configuration有問題時，zone的狀態會在incomplete，
此時可能會有無法uninstall、delete、重新設定等問題，此時就必須以手動刪除失敗的zone。
1. remove the zone entry in /etc/zones/index（假設失敗的是zone3，就把該行字串刪除）:
global:installed:/
zone1:installed:/zones/zone1
zone2:installed:/zones/zone2
zone3:incomplete:/zones/zone3
2. delete the xml file associated with the zone under /etc/zones
3. delete the directory associated with the zone (if it has been created)
