Open Stack

Hello,

Could you please advice a technical decision how to made a choice between linuxbridge and Open vSwitch for 
an OpenStack deployment ?

While Open vSwitch is more flexible and provides more features, it also involves additional level of complexity.

However, are there OpenStack features which can only be utilised using Open vSwitch functionality or is it implemented
in OpenStack just as an option to choose?

According to https://www.ibm.com/support/knowledgecenter/en/linuxonibm/liaag/wkvm/wkvm_c_net_conbridge.htm,
there is no significant difference in the terms of performance, but Open vSwitch implies more additional attendance to
understand and debug network level.

I would appreciate a feedback based on real operation and maintenance experience.

Thanks,
Regards,
Serge.
