[libvirt] qemu: managedsave vs. save

Hi! My KVM hosts share the same filesystem and I'm facing an issue using managedsave. If I save vmX using managedsave on hostA and restore it later using "virsh restore" in hostB the qemu process consumes 100% CPU and makes no progress. On the other hand, if I save vmX using save the restore works fine on hostB. Why can't I restore vms saved by managedsave using restore? Or is this a known issue on libvirt-0.10.X (CentOS 6)? -- Thanks, //richard
