I have a motherboard with an integrated GPU that I have a separate monitor connected to that I would like to keep active to display any console messages.  I am passing through a secondary GPU to a Windows 8.1 VM.  It looks like the integrated GPU is turned off and doesn't display any more messages once the VM starts.  The boot messages up to the login are still on the display.  Can anyone provide any guidance on how to keep that display working?

 

EDIT: When I stop the VM, the keyboard works.  I can login into unRAID on the keyboard and reboot the system.  The main console just does not display any messages.

this might help : jonp ( I think ) has been adding a lot to the wiki lately especially for vm's and passthrough ,

 

a lot of good info in here >>> http://lime-technology.com/wiki/index.php/UnRAID_Manual_6#Assigning_Graphics_Devices_to_Virtual_Machines_.28GPU_Pass_Through.29

 

 

 

Warning: Passing through a GPU to a SeaBIOS-based VM will disable console VGA access

If you rely upon a locally-attached monitor and keyboard to interact with the unRAID terminal directly, you will lose this ability once you create a SeaBIOS VM with a GPU assigned. This is due to a bug with VGA arbitration and cannot be solved. This does NOT affect your ability to access the console using a telnet or SSH session, but local console access directly will appear to be frozen (blinking cursor, but no visible response to keyboard input). It does not matter if you are using on-board graphics for the console compared to a discrete GPU for the pass through to a VM or not. With OVMF, however, VGA isn't utilized, therefore arbitration isn't needed and therefore your console graphics will remain intact. Note that not all GPUs support OVMF as OVMF requires UEFI support on your GPU.

Ok.  That's the exact situation I have.  I won't re-create the VM with OVMF just to get the console back.
