@rafaelweingartner thanks for reviewing! I couldn't find any document with
all cluster_details, however we could find out that this property could be
defined like in
<code>cloudstack/engine/components-api/src/com/cloud/alert/AlertManager.java</code>,
those properties are inserted in <code>configuration</code> table, specifying
the class which defines it in <code>component</code> field.
I think this new property <code>cluster.storage.operations.exclude</code>
could be done that way, do you agree? In that case, in which component could it
be defined?

> Key: CLOUDSTACK-9333
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9333
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: VMware
> Affects Versions: 4.9.0
> Reporter: Nicolas Vazquez
> Fix For: 4.9.0

> h1. Introduction
> In some environments there is a need to exclude certain VMware clusters from
> performing OVF operations. This operations are part of:
> * create template
> * create volume snaphsot
> * copy template, volume, images from primary storage to secondary storage
> * migrate volume
> * participate when a template gets cached over to primary storage.
> In ESX/ESXi, OVF operations are low priority and bound to a single CPU and
> most likely get throttled to certain IOPS and network limits.
> If the hypervisor chosen for OVF operations is weak or overloaded this
> results in significantly longer execution of such OVF command and therefore
> degraded performance of underlying CloudStack API call.
> h2. Proposed solution
> It is proposed to add a way to exclude hosts from selected clusters for OVF
> operations.
> To exclude a cluster, would be necessary to insert a record in
> {{cluster_details}} specifying property *{{'vmware.exclude_from_ovf'}}* in
> this way: (supposing we want to exclude cluster X)
> ||cluster_id||||name||value||
> |X|vmware.exclude_from_ovf|true|
