The App Volumes operation mode is determined by configuring the Machine Manager. The Machine Manager determines the type of hypervisor connection.
|Hypervisor Connection Type||Description|
|VMware vCenter Server||Preferred connection type for mid-to-large environments. Enables the use of VMDK Direct Attached operation mode. When using this connection type, you can assign Applications, Packages, AppStacks, and Writable Volumes to the virtual machines running on multiple hypervisor hosts.|
|Single ESXi Host||Enables the use of VMDK Direct Attached Operation Mode, but only for a single ESXi host. Use this connection type for small deployments and proofs of concepts. You can assign Applications, Packages, AppStacks, and Writable Volumes to the virtual machines running on a single hypervisor host.|
|VHD In-Guest Services||Disables other hypervisor connections and enables the use of VHD In-Guest operation mode. Use this connection type to assign Applications, Packages, AppStacks, and Writable Volumes either to virtual machines running on an unsupported third-party hypervisor or to the physical computers. See Configure VHD In-Guest Storage.|
Reconfigure vCenter Server
If you regenerate new certificates for ESXi hosts and you have selected vCenter Server as your machine manager, with the Mount ESXi option, you must reconfigure your vCenter Server.
See Regenerate Certificates for an ESXi Host section in the VMware vSphere ESXi and vCenter Server 5 Documentation.
vCenter Server Permissions
The following permissions are required if you are configuring a vCenter Server as the machine manager.
You also require these permissions if you choose the Mount ESXi option when you are configuring the machine manager.
|Host||Local Operations -> Reconfigure virtual machine
|Sessions||View and stop sessions
Note: This permission is not required for the VMware Cloud on AWS environment.
