If you only need the disk to stay the same and you want to easily migrate existing machines, then virt-v2v might be good to try. You might be able to get that info using libguestfs (virt-v2v should be able to do that for you). You don't need to have a libvirt network for each VM, you can create a bridge and use <interface type='bridge'/> or just use <interface type='direct'/>. Or you can have one network for multiple VMs. What did you use with plain QEMU? I'm not sure what the trouble is, also what the use cases are, so the answers might not be fit for your needs. dynamic_ownership=0 keeps the owners as they are, but libvirt cannot guarantee that the VM will have access to all its resources. If you are taking care of that, then keeping that turned off should be OK.
