[Po-Hsu Lin (cypressyew)]

This failure seems to be caused by the hanging lxc-test-apparmor-mount test, which got killed by the 900 seconds timeout setting on these 3 instances (c3.xlarge, t3.medium, t3a.2xlarge)

Normally this test will take about 30 seconds to run. But somehow it hangs in this case.

I have the test restarted on these 3 failing instance and they're all green now.
