Tried to use this implementation. Used the
topic/gvt-next-kvmgt-mdev-2016-11-18 branch which looked like the most
recent one. Setup:
* Everything compiled as modules.
* iommu turned off for the igd (intel_iommu=on,igfx_off).
* Blacklisted i915 so dracut initrd doesn't load it
(rd.driver.blacklist=i915)
* tweaked module config so kvmgt is loaded before i915,
also enable gvt:
# cat /etc/modprobe.d/kraxel-gvt.conf
options i915 enable_gvt=1
softdep i915 pre: kvmgt
Everything seems to load fine. Sysfs files are there, and I can create
vgpus.
Trying to assign a vgpu this way:
-device vfio-pci,sysfsdev=/sys/class/mdev_bus/0000:00:02.0/<uuid>
fails though and gives this message in the kernel log:
[ 402.560350] [drm:intel_vgpu_open [kvmgt]] *ERROR* gvt: KVM is
required to use Intel vGPU
Trying the same with a mtty sample device works and I can see the pci
serial device in the guest.
Any clues what is going wrong?
Has this version any support for exporting the guest display as dma-buf,
so qemu can show it? Or is this a headless vgpu?
thanks,
Gerd
