Hi All: I'm deploying duplex container mode with latest code . meet some error for neutron-ovs-agent Both controller have same configuration and deploy in virtual machine (qemu kvm env) . Does anyone have similar experience and suggest how to solve it ? *) The status of neutron-ovs-agent: neutron-ovs-agent-controller-0-a762cb46-h9xqw 0/1 Init:CrashLoopBackOff 11 42m neutron-ovs-agent-controller-1-f2c6aeed-427h8 1/1 Running 0 42m *) The log of neutron-ovs-agent-controller-0-a762cb46-h9xqw is : + timeout 3m neutron-sanity-check --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/openvswitch_agent.ini --ovsdb_native --nokeepalived_ipv6_support Guru meditation now registers SIGUSR1 and SIGUSR2 by default for backward compatibility.
