Since 363e9a68 we track backing chain metadata when creating snapshots the right way even for the inactive configuration. As we did not yet update other code paths that modify the backing chain (blockpull) the newDef backing chain gets out of sync.
After stopping of a VM the new definition gets copied to the next start one. The new VM then has incorrect backing chain info. This patch switches the backing chain detector to always purge the existing backing chain and forces re-detection to avoid this issue until we'll have full backing chain tracking support.

ACK. It's a bandaid that may disappear later, but it's better to ship something inefficient and working rather than efficient but buggy. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
