There is no defined limit to the number of policies that you create. However, the more placement constraints you create, the more challenging it is for vSphere DRS to effectively move virtual machines within the cluster and provide the resources needed by the workloads.
Make sure to review the requirements for the policy type.
In your Azure VMware Solution private cloud, under Manage, select Placement policies > + Create Policy.
You may also select the Cluster from the Placement Policy overview pane and then select Create.
Provide a descriptive name, select the policy type, and select the cluster where the policy is created. Then select Enabled.
If you disable the policy, then the policy and the underlying DRS rule are created, but the policy actions are ignored until you enable the policy.
If you selected VM-Host affinity or VM-Host anti-affinity as the type, select + Add hosts and the hosts to include in the policy. You can select multiple hosts.
The select hosts pane shows how many VM-Host policies are associated with the host and the total number of VMs contained in those associated policies. And then select the affected VM. In our case they will be the usual suspects.
