From 946dd98e911e62c7bc3bcdd8adc8a170645c981c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Bosdonnat?= <cbosdonnat@suse.com> Date: Wed, 6 Jun 2018 09:49:36 +0200 Subject: [PATCH] virt.pool_running: fix pool start Building a libvirt pool starts it. When defining a new pool, we need to let build start it or we will get libvirt errors. Also backport virt states test to add test for the bug: cherry picked from commits: - 451e7da55bd232546c4d30ec36d432de2d5a14ec - 495db345a570cb14cd9b0ae96e1bb0f3fad6aef0 - cb00a5f9b4c9a2a863da3c1107ca6458a4092c3d - fc75872fb63e254eecc782168ff8b37157d9e514 - 2a5f6ae5d69be71daeab6c9cbe4dd642255ff3c6 - 2463ebe5a82b1a017004e8e0e390535485dc703e - c7c5d6ee88fbc74d0ee0aeab41beb421d8625f05 --- salt/states/virt.py | 7 +- tests/unit/states/test_virt.py | 508 ++++++++++++++++++++++++++++++++- 2 files changed, 508 insertions(+), 7 deletions(-) diff --git a/salt/states/virt.py b/salt/states/virt.py index 90693880df..d411f864cd 100644 --- a/salt/states/virt.py +++ b/salt/states/virt.py @@ -780,7 +780,7 @@ def pool_running(name, source_name=(source or {}).get('name', None), source_format=(source or {}).get('format', None), transient=transient, - start=True, + start=False, connection=connection, username=username, password=password) @@ -795,11 +795,6 @@ def pool_running(name, connection=connection, username=username, password=password) - - __salt__['virt.pool_start'](name, - connection=connection, - username=username, - password=password) ret['changes'][name] = 'Pool defined and started' ret['comment'] = 'Pool {0} defined and started'.format(name) except libvirt.libvirtError as err: diff --git a/tests/unit/states/test_virt.py b/tests/unit/states/test_virt.py index 2e421319ad..8022989937 100644 --- a/tests/unit/states/test_virt.py +++ b/tests/unit/states/test_virt.py @@ -21,6 +21,25 @@ from tests.support.mock import ( #
