File fix-virt.full_info-176.patch of Package salt.12957
From 4ce0bc544174fdb00482db4653fb4b0ef411e78b Mon Sep 17 00:00:00 2001 From: Cedric Bosdonnat <cbosdonnat@suse.com> Date: Tue, 3 Sep 2019 15:18:04 +0200 Subject: [PATCH] Fix virt.full_info (#176) * virt.get_xml doesn't take a domain object In some places in the virt module, the get_xml function was called with a domain object, leading to runtime errors like the following one: 'ERROR: The VM "<libvirt.virDomain object at 0x7fad04208650>" is not present' * qemu-img info needs -U flag on running VMs When getting VM disks informations on a running VM, the following error occured: The minion function caused an exception: Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/salt/minion.py", line 1673, in _thread_return return_data = minion_instance.executors[fname](opts, data, func, args, kwargs) File "/usr/lib/python3.6/site-packages/salt/executors/direct_call.py", line 12, in execute return func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/salt/modules/virt.py", line 2411, in full_info 'vm_info': vm_info()} File "/usr/lib/python3.6/site-packages/salt/modules/virt.py", line 2020, in vm_info info[domain.name()] = _info(domain) File "/usr/lib/python3.6/site-packages/salt/modules/virt.py", line 2004, in _info 'disks': _get_disks(dom), File "/usr/lib/python3.6/site-packages/salt/modules/virt.py", line 465, in _get_disks output = _parse_qemu_img_info(qemu_output) File "/usr/lib/python3.6/site-packages/salt/modules/virt.py", line 287, in _parse_qemu_img_info raw_infos = salt.utils.json.loads(info) File "/usr/lib/python3.6/site-packages/salt/utils/json.py", line 92, in loads return json_module.loads(s, **kwargs) File "/usr/lib64/python3.6/json/__init__.py", line 354, in loads return _default_decoder.decode(s) File "/usr/lib64/python3.6/json/decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib64/python3.6/json/decoder.py", line 357, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) This is due to the fact that qemu-img can't get infos on a disk that is already used like by a running VM.
