You're talking about live block/storage migration, right? if so, shared 
storage isn't necessary, please refer to the following link:
  http://wiki.qemu.org/Features/LiveBlockMigration

But I'm not sure it has been supported by qemu-kvm rpm on the RHEL, you 
probably require qemu-kvm-rhev installation.
In addition, could you show your qemu-kvm or qemu-kvm-rhev version and 
relevant libvirtd.log? thanks.
