I just upgraded one of my hosts to U1 and when I click on the host and view the cpu summary tab it reports no information available for this host. When I view the VM's everything is displayed with no problems. Also when I view the Datastore I recieve a message stating there are no vm's running on the storage device.
Are there any known issues running U1 and monitor 4.5? Resources of the VMs seem to all be reported correctly.
