A node cannot be removed from a cluster until it has been placed in maintenance mode. This will ensure that all of the VMs on it have been migrated to other Hosts. To remove a Host from the cloud:

To remove this type of host, first place it in maintenance mode, as described in <a class="xref" href="scheduled-maintenance-maintenance-mode-hosts.html">Section 11.2, “Scheduled Maintenance and Maintenance Mode for Hosts”</a>. Then use CloudStack to remove the host. CloudStack will not direct commands to a host that has been removed using CloudStack. However, the host may still exist in the vCenter cluster.
