[libvirt-users] Live Block Migration with additional attached storage

Dear all, I am planning to use live block migration with one VM running on local disk and also attached additional disk from iSCSI or other shared storage. When block migration, not only local VM disk is copied to the destination but also the attached additional disk from shared storage. It is not desired in this situation. I just want the local VM disk is copied. Is there anyway to do this scenario? Does the concept of storage pool help this? I browse the source code but don't find hints right now. Thanks. Regards, Arnose
