When you use the placement policy for workload placement to place machines when you deploy new blueprints, be aware of the limitations.
In vRealize Operations Manager, the vRealize Automation solution identifies the clusters and virtual machines that vRealize Automation manages.
When vRealize Automation manages the child objects of a data center or custom data center container in vRealize Operations Manager, the ability to rebalance or move those objects is not available. You cannot turn on or turn off the exclusion of actions on vRealize Automation managed objects.
For the objects that vRealize Automation manages, the workload placement behavior is as follows:
When a custom data center or data center includes a cluster that vRealize Automation manages, workload placement does not allow you to rebalance the cluster.
When a cluster includes virtual machines that vRealize Automation manages, workload placement does not allow you to move those virtual machines.
vRealize Operations Manager does not support workload placement on resource pools in vCenter Server.
vRealize Operations Manager does not support vSAN in the current release.
