I have a Hyper-V R2 box that suffered a hard drive failure. Let me say, there was no redundancy in the box, but I was able to copy the folders for the 2 VMs that I needed to keep. Since I'm unable to boot and do a proper Export from Hyper-V, what are my options on getting these VMs working in a new installation? I know its not as simple as plopping them in a directory and having the server see them, and I can't import them without the .exp files.
The easiest thing to do is to copy the vhd disk to a directory on the new server.
Create a new VM in the Hyper-V manager and when it asks you whether you want to create a new disk or "use an existing virtual hard drive", choose the second option and select the VHD that you copied and start the VM.
It should work, I have recovered a couple of VM's this way.
