Hello sir,

I have installed a openstack trial platform in one server via the command “packstack –allinone”, the installation method only provide “OVN” neutron configuration.

When I try to create a network and launch a instance VM, the network’s port status is down, and launching instance failed. I try so many times, and then I think if the OVN network configuration is unavailable, and I want to modify the neutron configuration from ovn to openvswitch, but it’s a pity that re-deploy is always failing. The failing reason is prompted the following messages:

Error: Could not set 'present' on ensure: SSL_connect returned=1 errno=0 state=error: certificate verify failed

Its installing log is attached, could you help me to check why the error happed once again.

Thanks.
