Thanks for you reply. 

I was a little afraid to put my hands in openvswitch... I have tried and it's totally answer to my problematic. However, I think that there is a conflict between network-manager and openvswitch at the boot of host: Network manager fails with a timeout (5 minutes) to active interfaces and virtual bridges. 

Once logged on host, I have to make this to active all interfaces:
systemctl start networking.service # No time out anymore..., active all "regular" interface and "classic" bridge linux
systemctl stop networking.service 
systemctl start networking.service # No time out again, active all interfaces!

I have install net-tools package (apparently ifconfig is need by OVS...) and I have enable openvswitch-switch.service with systemctl:
systemctl enable openvswitch-switch.service

Is anyone ever encountering that?

Best regards.
