It turned out the ovs error message was a red herring. I have undefined and redefined the networks and now I don't see the error message any more, but that didn't solve my problem. It turned out that the problem that prevented the VM form starting was that I was using <backingStore> tags for disk volumes... This is onlu supported in v6.1.0, while I was using v6.0.0.
