As for issue 1, have you thought of implementing the stop
functionality as a combination of Snapshot+Terminate?
As for issue 2,
there is a blueprint  to deal with these sorts of scenarios.
Unfortunately that's not going to help you in the immediate term because
the effort hasn't started yet (for lack of time more than anything else).
Hope this help!

We are currently testing the
Openstack Nova product, but we have 2 problems/questions which we haven't
find a decent solution for yet.
1. In The Nova-api v1.1 there is no
option to Stop and Start an instance, only Reboot and Terminate. I know
that these options are available in v2.0 which is in Beta right
Because we would like to work with the stable version of the Nova-Api
we are not planning to move to v2.0 for now.
We are wondering if anyone
has managed to find a solution for this issue? Is there a 'clean' way to
implement and use a Stop and Start function in the API? We can of course
make an exception by using custom shell scripts for the stop and start
function (using virsh destroy/start) but this is kinda nasty ;)..
our Nova-Compute machines we have shared storage using an iSCSI target
which gives us the ability to use Live Migration. This is working
perfectly! The only problem we are facing at this moment is that we want to
be able to start an instance on a different Compute Node when the original
Compute Node goes down. Is there an easy way or (even better) an API call
which can be used for this? The Live Migration function does not work when
the original Nova Compute node is down. We are currently planning to
implement our own patch which detects a compute node going down and
automatically starts the instances on different compute nodes using various
algorithms. Only the last part (starting an instance on a different node)
is something we need to figure out, hopefully you guys can help! :)
