Nova is also not the right place to do the generic solution as many other parts could be involved... neutron and cinder come to mind. Nova needs to provide the basic functions but it needs something outside to make it all happen transparently. I would really like a shared solution rather than each deployment doing their own and facing identical problems. A best of breed solution which can be incrementally improved as we find problems to dget the hypervisor down event, to force detach of boot volumes, restart elsewhere and reconfigure floating ips with race conditions is needed. Some standards for tagging is good but we also need some code :-)
I agree with Tim. Nova does not have all the required information to make a proper decision which could imply other OpenStack (and non-OpenStack) services. Furthermore, evacuating a node might imply fencing which Nova might not be able to do properly or have the proper tooling. What about non-shared storage backend in Nova? You can't evacuate those without data loss.
