Link virtual machine created outside of virt-manager

[Jesus Jr M Salvo]

With FC7 x86_64 as the host OS, I have created a virtual machine with
win2k as guest using the command line via the following instructions:

http://kvm.qumranet.com/kvmwiki/HOWTO

Now is there a way to somehow "link" / "connect" what I have just done
so that I can launch the virtual machine using "Virtual Machine
Manager" ? If I select "File -> Restore Saved Machine" from "Virtual
Machine Manager" and specify the file image that contains the guest
OS, it says "The file xxxx does not appear to be a valid saved machine
image."

Thanks,

John
