Hi,

Yes, I did clean the root directory but it didn't solve the issue.
I'm currently running the tests on fedora27, using python version 2.1.14.

Thanks to Dan's help, it seems that we found the root cause:

I had 2 pickle files under /var/cache/vdsm/schema: vdsm-api.pickle and vdsm-events.pickle.
Removing them and re-running the tests using make check was successfully completed.

How did you have cached schema under /var/run? This directory is owned by root.
Are you running the tests as root?

No, I'm running the tests over my laptop using my user.

This sounds like a bug in the code using the pickled schema. The pickled should not
be used if the timestamp of the pickle do not match the timestamp of the source.

There's a suspect that there's a different encoding for python 2 and python 3.

While I checnged "with open(pickle_path) as f:" to "with open(pickle_path,'rb') as f: " (I was inspiered by [1]),

the make check seems to complete successfully.

Also in make check, we should not use host schema cache, but local schema cache
generated by running "make".
