I am running the gvt-stable-4.11 branch on Intel(R) Core(TM) i7-6600U CPU @
2.60GHz and after I run some 3D apps in the guest for just about a minute,
I start getting crashes. The host system becomes very sluggish. In dmesg
output I found this:
[ 1040.892234] [drm] GPU HANG: ecode 9:0:0x85ddfffb, reason: Hang on rcs0,
[ 1040.892235] [drm] GPU hangs can indicate a bug anywhere in the entire
gfx stack, including userspace.
[ 1040.892236] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 1040.892236] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 1040.892236] [drm] The gpu crash dump is required to analyze gpu hangs,
so please always attach it.
[ 1040.892237] [drm] GPU crash dump saved to /sys/class/drm/card0/error

Followed by a lot of stack prints (full dmesg:
Also, /sys/class/drm/card0/error here:
I am not sure whether it would be of any use.
I was getting similar stability issues on 4.10 branch and decided to try
4.11 before asking for help. One improvement I saw is that there is no
longer a kworker thread left after running a VM.
Another minor issue: for some reason on 4.11 I no longer
see i915-GVTg_V5_1, only i915-GVTg_V5_2, _4 and _8.
