[ovirt-devel] [OST/SDK4] ValueError: urandom is not a valid RngSource

Hi, I'm trying to run ovirt-system-tests from git master with basic-suite-master on my RHEL machine. The tests had been failing on missing ovirtsdk4 Python module, so I installed python-ovirt-engine-sdk4-4.0.4-2.el7ev.x86_64 package. Now the tests fail early and I'm getting the following error: File "/usr/lib64/python2.7/unittest/case.py", line 369, in run testMethod() File "/usr/lib/python2.7/site-packages/nose/case.py", line 197, in runTest self.test(*self.arg) File "/usr/lib/python2.7/site-packages/ovirtlago/testlib.py", line 129, in wrapped_test test() File "/usr/lib/python2.7/site-packages/ovirtlago/testlib.py", line 59, in wrapper return func(get_test_prefix(), *args, **kwargs) File "/home/pdm/ovirt/lago/ovirt-system-tests/basic-suite-master/test-scenarios/002_bootstrap.py", line 215, in add_cluster add_cluster_4(prefix) File "/home/pdm/ovirt/lago/ovirt-system-tests/basic-suite-master/test-scenarios/002_bootstrap.py", line 256, in add_cluster_4 ballooning_enabled=True, File "/usr/lib64/python2.7/site-packages/ovirtsdk4/services.py", line 3758, in add return readers.ClusterReader.read_one(reader) File "/usr/lib64/python2.7/site-packages/ovirtsdk4/readers.py", line 1740, in read_one obj.required_rng_sources = [types.RngSource(s.lower()) for s in Reader.read_strings(reader)] File "/usr/lib/python2.7/site-packages/enum/__init__.py", line 330, in __call__ return cls.__new__(cls, value) File "/usr/lib/python2.7/site-packages/enum/__init__.py", line 642, in __new__ raise ValueError("%s is not a valid %s" % (value, cls.__name__)) ValueError: urandom is not a valid RngSource Does anybody know what's wrong and how to make the tests working?
