If you want to connect to SCVMM with PVS you need to do some changes on the SCVMM server first. Now why would you add a connection to SCVMM from PVS?
Using a Provisioning Services streamed vDisk, the XenDesktop Setup Wizard assists in deploying virtual desktops to a number of cloned virtual machines (VMs) as well as to devices using the Personal vDisk feature.
System Center Virtual Machine Management (SCVMM) servers require that PowerShell 2.0 is installed and configured for the number of connections. The number of required connections for an SCVMM server should be greater than or equal to the number of hosted hypervisors used by the setup wizard for virtual machine cloning. For example: to set connections to 25 from a Powershell prompt, run: winrm set winrm/config/winrs @{MaxShellsPerUser=”25″}winrm set winrm/config/winrs @{MaxConcurrentUsers=”25″}. For Microsoft SCVMM to work with XenDesktop, the user must run the following PowerShell command; set-ExecutionPolicy unrestricted on SCVMM.
You might also need to run the winrm quickconfig on the SCVMM server.
Right click on Hosts, and select Add host, from the menu choose SCVMM/Hyper-V –>
Enter the IP Address of the server
Enter credentials and click verify.
NOTE: If you get any errors here, doublecheck the winrm config on the scvmm server and check that there aren’t any firewall blocking the connection.
