A host group is a vSphere host DRS group. A vSphere administrator must create host DRS groups in a resource pool mapped to a vCloud Director Provider VDC before they can be used in vCloud Director VM-Host affinity rules.

vSphere host DRS groups created in resource pools that are mapped to a Provider VDC appear in those resource pools and can be named in VM-Host affinity rules. For more information about host DRS groups, see the VMware vSphere ESXi and vCenter Server Documentation.


  • Host groups are properties of a resource pool. Select a resource pool from the Resource Pools list under vSphere Properties.
    Host DRS groups in the resource pool are listed on its Host Groups tab.
