Hi Matteo,

When power management is not available, we cannot do failover to other host.

In 4.1 you can use a VM lease for your HA VM, enabling failover without
power
management.

Note that the lease cannot be on Ceph storage domain, you will have to add
other type of storage for the leases, since we don't support leases on ceph
yet.

Please check the vm-leases feature page for more info:
