> Project: CloudStack
> Issue Type: Improvement
> Components: KVM
> Reporter: Wido den Hollander
> Assignee: Wido den Hollander

> Fix For: Future

>
> Just like NFS we should write a heartbeat for each Instance to RADOS.
> Each hosts could write a simple object like: <pool>/<host ip>
> They simply write the timestamp to the object encoded in JSON.
> Other hosts can read that object and see if the host wrote the timestamp
> lately. If it did it means that it is still up and running and Fencing is not
> needed or required.
