Hi!

I get accelerated graphics and the output of chrome://gpu is identical
betweem the host and LXD Chrome:

===
Graphics Feature Status

Canvas: Hardware accelerated
Flash: Hardware accelerated
Flash Stage3D: Hardware accelerated
Flash Stage3D Baseline profile: Hardware accelerated
Compositing: Hardware accelerated
Multiple Raster Threads: Enabled
Native GpuMemoryBuffers: Software only. Hardware acceleration disabled
  (i.e. Intel GPU)
Rasterization: Software only. Hardware acceleration disabled
Video Decode: Software only, hardware acceleration unavailable
Video Encode: Hardware accelerated
VPx Video Decode: Software only, hardware acceleration unavailable
WebGL: Hardware accelerated
WebGL2: Hardware accelerated
===

For my Intel GPU, I did not have to enable the LXD GPU Passthrough
(LXD 2.7 or later),
while others with NVidia had to do so. It would be great if someone
with Intel GPU could try the tutorial
and report back.
