Thanks for reporting this bug. I'll try to reproduce.
Could you post the xml file for one of the domains that fails to migrate?
Could you edit /etc/libvirt/libvirtd.conf on both hosts to set log_level = 1, then restart libvirtd (sudo stop libvirt-bin; sudo start libvirt-bin), re-try the migration, and post the /var/log/libvirt/libvirtd.log and /var/log/libvirt/qemu/VMNAME.log files?
