Fixed In Version: python-ovirt-engine-sdk4-4.3.0
Doc Type: If docs needed, set a value
Doc Text:
When using Python SDK with Python 3.7, you cannot use async parameter of service methods, as it was renamed to async_, because Python 3.7 come with reserver keyword async. In older Python versions you can still use async in SDK service methods, but you can also use async_.

Description Konstantin Shalygin 2018-08-24 09:08:42 UTC 
Description of problem:

Since python 3.7 ovirt-engine-sdk-python is unusable and should be updated because used reserved python words as arguments.

Why Severity is high: many desktop distro's at this time use python 3.7 as default python interpretator and this breaks all oVirt modules for Ansible.

Version-Release number of selected component (if applicable):

ovirt-engine-sdk-python-4.2.8

How reproducible:

Comment 3 Konstantin Shalygin 2019-02-11 08:32:09 UTC 
Version 4.3.0 works for me.
Thanks.
Comment 4 Jan Zmeskal 2019-02-14 14:36:28 UTC 
Verification steps: 

1. Create CentOS7 machine

2. Install python3.7 prerequisities
yum install -y gcc openssl-devel bzip2-devel libffi-devel

3. Get python3.7 source
cd /usr/src
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
tar xzf Python-3.7.0.tgz

4. Compile python3.7
cd Python-3.7.0
./configure --enable-optimizations
make altinstall

5. Verify installation
python3.7 -V

6. Get python SDK source 
cd /tmp
wget --no-check-certificate https://files.pythonhosted.org/packages/53/06/4faf279a5e58c7a6a28fcc865ba3b5b69c39ee786a5043ab1ccfb5d8c75e/ovirt-engine-sdk-python-4.3.0.tar.gz
tar xzf ovirt-engine-sdk-python-4.3.0.tar.gz

7. Compile python SDK
cd ovirt-engine-sdk-python-4.3.0
yum install libxml2-devel libcurl-devel
export PYCURL_SSL_LIBRARY=openssl
python3.7 setup.py install

8. Verify that everything worked in python interactive session
python3.7
