Hi,

To add more context, I also found this bug this week when I tried to add a new node to my Openstack Cluster newly installed (Bobcat version) .

Editing /etc/environment files with those values don't help :
LANG=en_US.utf-8
LC_ALL=en_US.utf-8

Regards

Benjamin

Hello Benjamin,

We also found this issue, and it can be reproduced when you connect libvirt using python, just wondering which version of libvirt rpm and libvirt-python pip package you are using?

Thanks
