FWIW, you use 'managedsave' then you shouldn't use 'restore' - you
should just 'start' the guest as normal and libvirt will automagically
use the managed save image.

Of course this doesn't explain the problem you see - the result of
managedsave should be identical to the result of save. They use the
same QEMU code internally, the only difference being that in one
case you decide the filename and in the other case libvirt decides
the filename
