What is Quick Migration in Hyper-V on Windows Server 2008, and is Live Migration supported in this release?

• A. Quick Migration moves a running VM to another host with a brief pause; Live Migration is not supported in Windows Server 2008.
• B. Quick Migration creates a backup snapshot.
• C. Live Migration is supported in Windows Server 2008.
• D. Both migrations are not possible.

Answer: (A)

Hyper-V migration options and downtime are being tested here. In Windows Server 2008, Quick Migration is the feature that moves a running virtual machine to another host with a brief pause in service. The VM is paused just long enough to transfer its state and memory to the destination, then it resumes on the new host. Live Migration—the ability to move a VM without noticeable downtime—is not supported in this release; that capability appears in later Hyper-V versions. So the described behavior of Quick Migration plus the lack of Live Migration matches what Windows Server 2008 Hyper-V actually provides.
