To change network interfaces on XenDesktop machine catalogs

When you are adding a new XenDesktop host to your XenDesktop 5 deployment, you will select the guest network that all created desktops will have as thier default.

As with most configuration in XenDesktop 5, changing what this network is after the initial setup requires PowerShell and some manual intervention

For existing virtual desktops, reconfigure the network interfaces manually through the vCenter console – i.e. right click the desktops and edit settings, change network label.

To ensure that all future desktops are then created with the correct interface the default has to be changed using PowerShell
First, open a PowerShell console as administrator.

Load the Citrix cmdlets:
Add-PSSnapin "Citrix*"

Discover the network path:
get-item xdhyp:\hostingunits\<hostname>

Where ‘hostname’ is what the virtual infrastructure is named as in the XenDesktop Desktop Studio console. (In the main view select Configuration -> Hosts -> and look for the server name for the vCenter server or XenServer resource pool)

Type this command:
get-item xdhyp:\hostingunits\<hostname>

The results should be returned, and one line will be:
NetworkPath          : XDHyp:\Connections\Melbourne\ESX.datacenter\Lab.cluster\OLD.network

Use the information to change the network path as required:
set-item xdhyp:\hostingunits\<hostname> -networkpath XDHyp:\Connections\Melbourne\ESX.datacenter\Lab.cluster\NEW.network

New Network Path will be the network interface name as it appears in vCenter console, appended with “.network”.
After this is complete, any new XenDesktop virtual machines created using MCS will have the new network interface assigned automatically.
