Re: [Xen-devel] GPU passthrough issue when VM is configured with 4G memory

[David TECHER <davidtecher@xxxxxxxx>]

Hi Youenn,

Good to know that it works for you :)

You should be well advised to share expected information for both your motherboard and your Nvidia graphic card.

(VGA PassThrough, Nvidia) works for Win7 with very rare exceptions.

Kind regards.

David.
