This step is buggy on older servers; it was fixed in upstream libvirt
0.9.4 to refuse deletion unless you first ensure that any managed save
metadata has been removed (also, 0.9.5 also refuses deletion unless you
first ensure any snapshot metadata has been removed, but that does not
appear to be your problem).

start is trying to reuse the stale managed save image that was left
behind by the older domain that was not completely undefined. You
should be able to correct the problem by doing 'virsh managedsave-remove
rmdev2' before 'virsh start rmdev2'.

Yep, and that's why newer libvirt prevents this situation from happening.
