Which configuration did you use? Or You configured log plugin in neutron node? On Sat, Mar 21, 2020 at 10:02 PM Ignazio Cassano <ignaziocassano@gmail.com> wrote:
Sorry, I mean I added ssh access and then I removed it Openviswitch is a requirement for security group logs. So , if you read at the documentation, it suggests to modify iptables_hybrid on neutron node as well.
1 month ago I addes a compute node with openvswitch on an openstack with iptables_hybrid on neutron node: it did not worked until I modified the neutron node. I do not know why

I just use Openvswitch for firewall driver. I did not use log plugin.
You said you conffigured sec group rules to allow and deny. As I know, Security group cannot add deny rule.

Sa, have you modified only the compute node side ? I've modified also the controller node (neutron node) side ad reported in documentation for enabling security groups logs.

One problem which I got few days ago.
I have existing openstack with iptables_hybrid. I changed the firewall driver to openvswitch then restart neutron-openvswitch-agent. I couldn't reach that VM any more. I tried to reboot or hard reboot that VM but It didn't work.

Sure, Sa. I have tested it 2 minutes ago. It works . I also changed security groups rules to allow/deny ssh access . It works also after hard reboot Ignazio

With VM uses provider network directly, When I hard reboot that VM, I cannot reach that VM again. Can you test in your environment?
