yes, installed with latest vmtool. the source VM freshly installed OS and nothing running except OS. I can clone on cold vm, only failed when it was started up. i have try disable the anti-virus and it's still same error. also try uninstall vmtool then reinstall back, still same. coud it be issue on version 5.0 since i'm using vCenter 5.0 and ESXi 5.0.
