aha, there is !

# ls /var/lib/libvirt/qemu/save
rmdev2.save
# virsh managedsave-remove rmdev2
Removed managedsave image for domain rmdev2
# virsh start rmdev2
Domain rmdev2 started

it seems an easy trap, because the answer of "how do I remove a vm" is
just "undefine vm_name", everytime, everywhere, and however google was
not helping much...

and I didn't know rhel6 is old by now
# rpm -q libvirt
libvirt-0.8.7-18.el6_1.1.x86_64

thanks eric and david !
