> [Hyper-v] Putting host in maintenance mode does not migrate the guest vms and VRs running on it to another available host in the cluster
> Steps to Reproduce:
> ================
> 1.Bring up CS in advanced zone with two or more hosts in the cluster with shared storage using SMB for both primary and secondary
> 2.Deploy few vms(Non-ha enabled) such that vms are distributed across both the hosts
> 3.Put one host in maintenance mode
> Expected Result:
> ==============
> Host should go to maintenance mode and all the vms running on it should be migrated to another host
> Actual Result:
> ===========
> Host transitioned into maintenance mode but all the vms running on it were not migrated to another host
> In case of host failure only non-HAed vms should be stopped but when the host is put in maintenance mode from CS all the vms running on it should be migrated and should be started on another available hosts in the same cluster.
