-Is your hardware on the HCL for 5.5 (lots are not) Yes. Running Dell M620 blades, among other things.
-When using the web interface does the hardware tab show up as refreshed? The issue is on both the web interface and vCenter client.
Restarting the VirtualCenter Management Webservices service seems to kick things back on temporarily, but I don't expect it to work for more than a couple of days based on previous experiences. We could have the service restart once/day, but I was hoping there would be a real fix for this.
Thanks.
