示例1: validatePendingEngine

// of the lock yet.

}
// The following is critical and fast. Grab a lock.
c.Lock()
defer c.Unlock()
// Only validate engines from pendingEngines list
if _, exists := c.pendingEngines[engine.Addr]; !exists {
return false
}
// Make sure the engine ID is unique.

log.Errorf("ID duplicated. %s shared by %s and %s", engine.ID, old.Addr, engine.Addr)
// Keep this engine in pendingEngines table and show its error.
// If it's ID duplication from VM clone, user see this message and can fix it.
// If the engine is rebooted and get new IP from DHCP, previous address will be removed
// from discovery after a while.
// In both cases, retry may fix the problem.
