Status in linux-lts-xenial package in Ubuntu:

Bug description:
Hello,
We just noticed that systemd's autopkgtests have started failing often
on amd64 for all releases, when run in Canonical's scalingstack cloud.
This is nested KVM I think.
TEST RUN: Basic systemd setup
+ /usr/bin/qemu-system-x86_64 -smp 1 -net none -m 512M -nographic -kernel
/boot/vmlinuz-4.10.0-19-generic -drive
format=raw,cache=unsafe,file=/var/tmp/systemd-test.unFR7V/rootdisk.img -initrd
/boot/initrd.img-4.10.0-19-generic -machine accel=kvm -enable-kvm -cpu host
-append 'root=/dev/sda1 raid=noautodetect loglevel=2 init=/lib/systemd/systemd
ro console=ttyS0 selinux=0 systemd.unified_cgroup_hierarchy=no '
KVM: entry failed, hardware error 0x0

I have observed a failure on the compute node (region lgw01)
Linux amemasu 4.4.0-59-generic #80~14.04.1-Ubuntu SMP Fri Jan 6
18:02:02 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
and a pass of the exact same package on the compute node (region
lcy01)
Linux kissel 3.13.0-95-generic #142-Ubuntu SMP Fri Aug 12 17:00:09
UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Here's an example log-

I found bug #1329434 which looks more or less identical and was fixed
for 3.13. Perhaps it regressed in 4.4?
