Hello there, I have installed the ESXI 5.5 on the DELL OPTIPLEX 780, and successfully passthrough the HD6450 into win7,but when I wanted to shutdown/restart the win7, the process seemed to be fine, but the state on the vCenter was always on, althrough I shutdown the VM's power, and then I had to restart again the ESXI to start the win7. So, did anyone meet this problem? Please help me.
