Hello All,
My goal is to run hyper-v with OVS as a compute node the installers provided by Cloudbase helped a lot, but i faced a few problems as follows:
Setup:
Windows server 2019 standard
OVS 2.7 certified worked only: other builds had an issue with pnputil.exe -e the version of the driver version be old and and say 1.0 and OVS wouldn’t run yielding unable to load kernel module error
I had another problem with continues disconnection to the OVS DB moving to windows server 2019 from 2016 kinda solved the issue
Openstack Train
My current problem is that Nova runs fine i can create an instance and would move to Running but the vif creation would fail and no network on the instance.
Any help is very much appreciated.
