Restart “Citrix Machine Creation Service” on all DDCs to trigger the  Machine Creation Service(MCS) inventory tree rebuilding. 

Problem Cause

VM info is not in  Machine Creation Service(MCS) inventory tree with unexpected reason.

When the hypervisor connection is created for the first time, MCS requests to populate the inventory tree.
It does so by getting all the VM details in virtual center and storing it in the Tree-Info node. MCS also spins up another lifecycle thread which listens for updates from VMWare.
This thread keeps tracks of the events received from VMWare about any VM getting added or deleted on the virtual center. After receiving the event, MCS updates its inventory tree to the latest accordingly.
