The lockd plugin for the lock manager was not correctly handling the release of resource locks. This meant that during migration, or when pausing a VM, the locks would not get released. This in turn made it impossible to resume the domain, or finish migration --- src/locking/lock_driver_lockd.c | 38 ++++++++++++++++++++++++++------------ 1 file changed, 26 insertions(+), 12 deletions(-)

So the old code released the first resource,
- goto cleanup; + for (i = 0 ; i < priv->nresources ; i++) {
but the new code loops over all resources. Yeah, I could see how that causes a problem if more than one resource is held. ACK. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
