After I noticed your crash I did ran some tests with 4.1.9 on physical
host (old core2duo) with kvm guest..
nfs client/server between guest/host + X on guest, next kvm guest to
force host to swap some memory to create memory pressure and all this
with 'perf top' on host machine without any problems..
