Bug Description
Update2: Switching from cgroup-lite to cgmanager will trigger this failure, see comment #4
Update1: this can be reproduced with kernel downgraded to 4.4.0-98, see comment #1
This test has passed with older kernels (4.4.0-98, 4.4.0-97, 4.4.0-96), but this time it failed.
Issue can be seen on zKVM, zVM and Ubuntu on LPAR
Steps:
1. Install lxc-tests
2. Run sudo /usr/bin/
Result:
---
mount: wrong fs type, bad option, bad superblock on none,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
umount: /tmp/tmp.
/usr/
Path existed
Using image from local cache
Unpacking the rootfs
---
You just created an Ubuntu container (release=xenial, arch=s390x, variant=default)
To enable sshd, run: apt-get install openssh-server
For security reason, container images ship without user accounts
and without a root password.
Use lxc-attach or chroot directly into the rootfs to set a root password
or create user accounts.

The mount error (bug 1730915) is not the cause, it looks like the failure was caused by:
call to cgmanager_
In that shell script, this line account for the error:
