Comment 1 for bug 1791682

This would arguably require a microversion since it would be an API change to allow live migrating suspended VMs:

https://github.com/openstack/nova/blob/fa7df873dce8f6f2dab2785ecf68def7c5d104b3/nova/compute/api.py#L4313

And we'd have an upgrade impact to that as well since the API would need to check with the compute to see if it can handle live migrating a suspended VM, because you could have old computes that don't have the code, or the instance is running on a virt driver that doesn't support this.
