I have found the cause.
It was running the cgm command from cgroup-lite package.
But during the last SRU cycle, it got replaced by cgmanager package.
If you switch to the cgroup-lite, the SUT will pass with this test.

** Description changed:
- This is a POTENTIAL REGRESSION.
+ Update: 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
This test still fail with 4.4.0-101 on s2lp6g001 (zKVM).
However, I have switched to 4.4.0-98, lxc-test-unpriv failed too.
This error message (call to cgmanager_move_pid_main_sync failed: invalid
request) seems to be caused by command:
cgm movepid freezer x1 $$
