** Also affects: python3-lxc (Ubuntu)
Importance: Undecided
Status: New
** Description changed:
The ubuntu_lxc test will timeout on some Impish test systems:
* baltar.ppc64el.9
* kernel03.s390x.zvm
* kuzzle.arm64
* rizzo.amd64
* s2lp4.s390x.lpar
+
+ It didn't hang on some instances because:
+ * dryden.ppc64el - test setup failed at the very beginning
+ * scobee-kernel.arm64 - unable to fetch GPG key on this maas (bug 1939871)
+ * vought.amd64 - unable to fetch GPG key on this maas (bug 1939871)
+ * appleton-kernel.arm64 - unable to fetch GPG key on this maas (bug 1939871)
The test log shows the api_test.py test timeout and getting nuked:

No default root or user password are set by LXC.
Timer expired (900 sec.), nuking pid 98177
However, the process is still running:

Thus causing the whole test suite to hand, and eventually being killed
by the jenkins timeout setting.
I tried to run this test manually on a KVM node, it will hang with "Getting
the IP addresses":
- $ time sudo /usr/share/doc/python3-lxc/examples/api_test.py
+ $ time sudo /usr/share/doc/python3-lxc/examples/api_test.py
