All,

I am getting an error message on VB where it will not start the session because of the following message:

"Unknown configuration value 'GetHostTimeDisable' found in the configuration of VMMDev instance #0 (VERR_CFGM_CONFIG_UNKNOWN_VALUE)."

Could anyone please assist me with resolving this issue. Thanks in advance

Maybe if you tell us how this error came about. Is this a transplant, or did you try to disable the get host time using VBoxManage? Are you using a 3rd party application like vagrant?

Yes, I was trying to disable the Get Host Time through the windows cmd prompt using the following cmd. vboxmanage setextradata "vbox name" VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled 1.

I think I may have input GetHostTimeDisable 1 instead of GetHostTimeDisabled 1. I did try re-running the cmd with the proper input, but I am still getting the same error message.

You need to re-run the erroneous command with an empty input (see 2nd command below). That will delete the wrong token/value combination and will allow you to start the VM. So, from the Command Prompt enter the following two commands:

• 
  VBoxManage setextradata "<VM>" "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" 1
  VBoxManage setextradata "<VM>" "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisable"

The first is the correct one (see Ch. 9.14.4 in the User Manual) and the second one will "cancel" the wrong entered one.
