Hi Dulko Thanks for your reply.

My OS is Centos 7.6 + python 3.7 Kuryr-daemon --version = 2.1.0

I run the kuryr-daemon as root. I run the kuryr not as pods. I will show you the conf of kuryr-daemon:

Waiting for your reply.

Thanks. ==========================================

<snip!> Please don't remove mailing list from the thread. Hm, I googled some older answer that maybe privsep-helper is not installed where kuryr-daemon is executed? In terms of Kuryr stuff that file has almost nothing set, so it isn't really giving much information, so - what's the Neutron plugin being used? Is the [kubernetes]pod_vif_driver just neutron-vif? I think for that to work you need to set [neutron_defaults]ovs_bridge for the daemon and [neutron_defaults]pod_subnet for controller. Can you enable debug for more logs from the error?

Hi,

This seems pretty vague, but my first bet would be that kuryr-daemon is not running as root? What's the exact configuration you use - i.e. Neutron plugin, Kuryr binding plugin (nested vs neutron), are you running Kuryr services as pods?

Thanks, Michał
