well I tried to fix the formatting so people could understand the problem. but I do not have 10 points to upload anything. Seriously you guy

After we restarted all the nodes after some networking issues on the hardware in the DC. The openvswitch seems to be messed up and using the wrong interface? We attempted to start the instances on the nodes but it gets a permission denied error. I notices the following errors on the ovs-vsctl show command. also dpdk does not work either. Please let me know what other logs i can get.

failed services: ovs-vswitchd.service loaded failed failed Open vSwitch Forwarding Unit ● sdkserver.service loaded failed failed zVM SDK API server ● systemd-networkd-wait-online.service loaded failed failed Wait for Network to be Configured

Please share detail server logs and nova-conductor logs. Looks some file ownership issue for that instance.
