  Hi,

Thanks, that brings us one step forward.

Linux guest can see the device (in lspci).  Trying to load i915.ko leads
to kernel oopses on both guest and host though.  So I guess the guest
driver can't handle the device.

I've tried RHEL-7.3, kernel 3.10.0-514.el7.x86_64.  The drivers/gpu/drm/
subsystem is roughly at upstream kernel v4.6 level.  Is that too old?
IIRC some vgpu guest patches have been merged in v4.2 timeframe, so I
kind-of expected this to work ...

I'll go try the kvmgt branch in the guest next.

What is the upstream merge status btw?  As far I know the bulk of the
gvt code is scheduled for 4.10.  What about the gvt/mdev plumbing?  Will
that land in 4.10 too or is that planned for 4.11?

thanks,
  Gerd
