We are currently running an hyperv cluster with storage spaces direct based on 3x nodes. We have OpenStack Ocata deployed as a single node / single VM through RDO.

When a node crashes and failover doesn't occur, instances might get shutoff by hyperv.

Is there a way to tell nova to automatically start these VMs without the need of manually starting these instances ?

Please let me know if you need further information.

Which Nova driver are you using? Make sure you're using HyperVClusterDriver, which will ensure that instances will be failed over when a host goes down.

Check out the following page for more details about the cluster driver:

There are a couple of config options (described in the above doc) that need to be set in order to ensure that failed over instances won't be turned off by Nova.

We're using the HyperVClusterDriver, however, there were some missing options that we've added. We will give it a try and see if that works. Cheers!
