Abstract
Embodiments of the present invention relate to a method and system for managing a virtual machine disk. According to embodiments of the present invention, thin provisioning and thick provisioning are integrated to form a hybrid virtual machine disk management mechanism. Specifically, for a thin provisioned VM disk, if it is determined that the load level of the disk is relatively high, it may be decided to switch the VM disk to be thick provisioned. On the contrary, for a thick provisioned VM disk, if it is determined that a load level of the disk is relatively low, it may be decided to switch the VM disk to be thin provisioned so as to avoid resource waste. In this way, the efficiency and flexibility of the management of virtual machine storage disks may be improved.
