Moving the storage of a (running) VM to a different (FC) storage domain fails.
Steps to reproduce:
1) Create new VM
2) Start VM
3) Start move of the VM to a different storage domain
When I look at the logs it seems that vdsm/libvirt tries to use an
option that is unsupported by libvirt or the qemu-kvm version on
CentOS 6.4:
"libvirtError: unsupported configuration: reuse is not supported with
this QEMU binary"
