I'm running a QubesOS 4.0, a security focused xen-derived operating system.
I'm trying to start a windows-VM with an Nvidia-gfx attached using xl
command line tools. I believe I've almost got it, but the nvidia-driver
doesn't correctly detect it.
What I've done so far: enabled pciback, successfully launched vm with
gfx attached as pci-device and played around with all settings in my
win7.cfg I could think of.
However, whenever I start the vm, windows detects the gfx as "3D graphic
acceleration", not nvidia-device. (which is, I believe, why the driver
doesn't detect it.)
I have since compiled a custom kernel, with the option
CONFIG_XEN_PCIDEV_BACKEND=y, to no avail.
Technically, the wiki specifies XEN_PCIDEV_BACKEND (no CONFIG), but
since all option started with "CONFIG" and the old kernel had
CONFIG_XEN_PCIDEV_BACKEND=m set, I belive the wiki has a typo? Can
anybody confirm this? (Since building takes quite some time, I'm
reluctant to just try it out.)
