[libvirt-users] Migrate doesn't support copy-storage-all

While using --copy-storage-all option while doing live migration I am getting following error : error: command 'migrate' doesn't support option --copy-storate-all I am using kvm hypervisor. Does that mean kvm doesn't support the option or libvirt doesn't provide support for the same with kvm as the hypervisor? -- Abhishek Student, IIT Delhi
