Abstract: In one aspect, a method includes receiving a first I/O at a kernel interface using a pseudo data storage system, writing the first I/O to a first virtual device on a datastore, receiving a second I/O at the kernel interface using the pseudo data storage system and writing the second I/O to a second virtual device on the datastore.

Abstract translation: 一方面，一种方法包括使用伪数据存储系统在内核接口处接收第一I / O，将第一I / O写入数据存储上的第一虚拟设备，在内核接口处使用第二I / O接收第二I / 伪数据存储系统并将第二I / O写入数据存储上的第二虚拟设备。

Abstract: In one aspect, a method includes powering down a target virtual machine (VM), removing the target VM from an inventory of virtual machine hosts after powering down the virtual VM, configuring a shadow VM by assigning an ID to the shadow VM to be the same as the target VM and by attaching a target VMDK to the shadow VM, adding the shadow VM to the inventory and powering up the shadow VM to run no more than a BIOS and to enable access of the target VMDK.
