Abstract: One or more embodiments provide techniques for promoting a linked clone virtual machine to a full clone virtual machine. In one embodiment, a method includes receiving an instruction to promote the linked clone virtual machine to a full clone virtual machine. The method also includes creating a second base disk for the linked clone virtual machine. The method includes installing a mirror driver between the first delta disk and the second base disk. The method includes copying the contents of the first delta disk to the second base disk with the mirror driver. After the contents of the first delta disk have been copied to the second base disk, the method includes removing the mirror driver and operating the linked clone virtual machine as a full clone virtual machine on the second base disk.

Abstract: A method for opening a virtual disk comprises reading information from a metadata file that identifies the current owner of the virtual disk. The method further includes sending a release request to the current owner of the virtual disk to release the virtual disk, writing information to the metadata file identifying the new owner, and then opening the virtual disk.

Abstract translation: 用于打开虚拟磁盘的方法包括从识别虚拟磁盘的当前所有者的元数据文件读取信息。 该方法还包括向虚拟磁盘的当前所有者发送释放请求以释放虚拟磁盘，向识别新所有者的元数据文件写入信息，然后打开虚拟磁盘。

Abstract: To create a backup of a live (running) virtual machine, a backup agent may take a snapshot of the virtual machine, backup the virtual machine from the snapshot disk, and delete the snapshot. Deleting the snapshot initiates a snapshot consolidation process where delta disks of the virtual machine are collapsed. A virtual disk layer sets up a mirror driver between a current virtual disk and a target virtual disk. Data sectors of the delta disk are copied over to the target virtual disk in a single pass, while the mirror driver mirrors write request for the current virtual disk to the target virtual disk.
