My Hyper V Virtual Machines reside on a Volume that is attached to a Compellent SAN.  As a test, I took a snapshot with the SAN of the volume, then went into the Hyper-V Manager and deleted the test Virtual Machine.  I then mounted the snapshot volume and copied the original vhd file, vm folder and xml file to their appropriate locations.  I stopped/started the Hyper-V service and the Virtual Machine I attempted to restored did not appear.  What is the process to get this machine up and running assuming you have nothing but a snapshot?

If you select the Folder, Do you have a Previous Folder Option?

 SAN Snapshot
or normally, the Snapshot is Read-only, and you present the Snapshot to the Server.

So, you Take a Snapshot, and then later if you require to rollback, you present this snapshotted iSCSI LUN to the Server. The would contain the data at the time you took the snapshot.

No, I do not.  I take a snapshot (or Compellent calls it a Replay) of the Volume, then have to mount the Replay to a server and then copy the data/files off manually.  In this case, I copied the files off to their original locations.

Okay, so once you've copied the files OFF the Snapshot location to the original locations?

they do not work?

No...it looks like I have to create a new VM, then attach the existing vhd file.  However, this creates a new VM folder and XML file.  Then when I boot the VM up to logon screen, I get the following error:

"There are currently no long servers available to service the logon request."

The network adapter is set to the appropriate adapter.  I even tried without an adapter hoping to at least logon as local.  I get the same error.

The reason I could not logon is because the first local area connection is gone.  A local area connection 2 was now enabled, but had no IP address and the subnet is statically assigned.  I logged on local, gave an IP and then was able to logon normally.  I'm not sure why I lost my first Local area connection though.
