kernel: 4.10.0-33.37~16.04.1
I think this issue was introduced by the old qemu version (similar issue was spotted on Xenial before), will need to investigate this further.

XFAIL: hypercall: h_random: h-call available
SUMMARY: 9 tests, 8 unexpected failures, 1 expected failures |
[Impact]
* Xenial with HWE kernel (matching new relesaes) and qemu without cloud
archive (not matching new releases) could trigger hypercalls that are
not supported in xenials-qemu.
* There is no "real" case other than kvm tests yet to trigger it yet, but
it is an easy and well contained fix, so we might fix proactively.
[Test Case]
1. deploy xenial + HWE kernel on a ppc64el box
2. sudo apt-get install qemu-kvm -y
3. git clone --depth=1 https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
4. cd kvm-unit-tests
5. ./configure --endian=little; make
6. sudo ppc64_cpu --smt=off
7. sudo ./run_tests -v
[Regression Potential]
* The changes are all upstream since a long time now (lowering the risk
of silly mistakes)
* The changes are isolated to ppc, so in the worst case only this arch
should regress.
* We implement new hcalls, so if anything there might be a regression if
software expected them to fail, but now breaks by them working (don't
think so given the nature of these hcalls).
[Other Info]
* n/a
