Hard to tell. I was hoping the trace could be of some help discovering the
reason.

Have you seen it with kernels before 4.6.3? Also please include the output of
grep -r . /sys/module/kvm*/parameters

Is there any chance you can try running a 4.5 or 4.4 kernel for a while? Also,
please include the configuration of the virtual machine (e.g. qemu command line
from "ps").
