[PVE-User] problem adding a graphics driver

Hi Lindsay,

Thank you for your email.  I tried Spice but realized that the VM has to recognize the video adapter to work with the program I need run.  It uses Unity Web Player which requires a better video card than the Standard VGA Adapter.  Ultimately the tests will be run without using a viewer from one VM to another (eggPlant).  You said that you wouldn't mess with the PCI Passthrough.  I wonder if anyone has tried and got it to work.

When I look at the Display Adapters installed in the Windows 7 VM it says I have:
Standard VGA Graphics Adapter
VNC Mirror Driver

When I try to update the Display driver(https://downloadcenter.intel.com/download/24329/Intel-HD-Graphics-Driver-for-7-8-8-1-64-bit)  first to Intel HD Graphics 4600 it gives me the following error:
This computer does not meet the minimum requirements for installing the software.


Unless you are using PCI passthrough (a different subject altogether and quite tricky), then your VM's virtual hardware is quite unrelated to the physical hardware it is running on.

By default its just a simple emulated VGA card. If you want ok video performance that scales to decent resolutions then you need to use the Spice Virtual Hardware and drivers.

- Shut the VM down

>From the Proxmox Web InterfaceI:
- Edit its Display in the Hardware Tab
- Set it to SPICE (Qxl)
- Start the VM

In the VM itself, install the Spice Guest Tools
- http://www.spice-space.org/download/windows/spice-guest-tools/spice-guest-tools-0.74.exe
- Reboot VM is Required

To *view* the VM's console, use the spice remote-viewer. That depends on what client system you are using to view the VM. For windows use the virt-viewer MSI available here:
 - http://virt-manager.org/download/

ignore the virt-manager stuff.


Remote Viewer and SPICE support nice things like dynamic resizing of the VM console. USB devices can be passed trhough.

Caveats:
- You'll never get game quality performance via spice, for that you'll probably need to do PCI passthrough of the host video card. Personally I wouldn't bother with that.


An alternative to using SPICE  onto a windows vm is to just use remote desktop (RDP), that works very well, but you do need to know the hostname/ip address of the VM.
