Hi all,

I've recently just started working with Hyper-V, and so far it's quite nice. However, I've been running into problems with what seems like it should be the most basic of workflows. I've set up a baseline Server 2008 R2 configuration, and exported it with the intention of using the export for cloning. I entered "C:\Exports\" as the export folder.

However, I run into problems when I try to import the image. From the Hyper-V manager, I select "Import Virtual Machine" and in the resulting window I entered "C:\Exports\BuildServer\" as the folder, set the radial to "Copy the virtual machine (create a new unique ID)" and checked the checkbox for "Duplicate all files so the same virtual machine can be imported again." Doing so results in the following error:

"Import failed. Import task failed to copy file from 'H:\Exports\BuildServer\Virtual Hard Disks\BuildServer.vhd' to 'C:\Hyper-V\Virtual Hard Disks\BuildServer.vhd': The file exists. (0x80070050)"

Have I somehow messed something up in configuration? Or is this a known thing? I've read it should be possible to clone VMs by copying them in the filesystem but I'd prefer to keep things in the management Ui if possible.
