From kvm 0.11.0 to kvm 1.0 loadvm problem

Hi, I have a server with kvm 0.11.0 and many vm (over 50). Each one has a saved status, and each time I run a vm I call loadvm.

Now I’m migrating to a new server with kvm 1.0 and loadvm does not work.

How can I manage it? I would like to recover all my vm status.

Thanks
