Describe what happens once you begin the QSM process.

What will be an ideal response?

When you begin the QSM process, VMM takes a snapshot of the running virtual machine, which creates a differencing disk.  All disk write operations from this point go to the differencing disk, while the original disk becomes read-only. VMM uses the Background Intelligent Transfer Service (BITS) to copy the original disk to the new location. This copy represents the bulk of the transfer; the virtual machine  continues to run. Once the copy of the original disk is complete, the virtual machine is placed in a saved state. The memory is copied to the new location. A merge combines the original disk, snapshot, disk writes, and memory in the new location. Once all of the elements are transferred, VMM exports and then imports the virtual machine on the same host computer to make the final changes to the virtual machine configuration file.
