If you run a Gentoo server with systemd, netctl and openvswitch, a boot of the server will fail to bring up the openvswitch device. Sometimes it happens that the ovs-switchd tries to connect the ovsdb-server, before the service is fully running and up. This seems to lead to a delay. At the same time netctl fails, because it has no dependencies to ovs-vsitchd. Adding a After=(ovs-vswitchd) statement to netctl does not solve the problem, as netctl seems to be broken here. So if you "netctl enable ovsbr0" for example, you have to manually edit the created profile and correct the After-statement. And this in turn makes problems with reboot. At this point nothing comes up cleanly. Neither ovsbr0, nor libvirt guests. I tried to find a solution, but this seems to difficult for me. I guess, there are some problems with the systemd-scripts provided by openvswitch and netctl (and the bug with broken After...) Reproducible: Sometimes Steps to Reproduce: 1. Install systemd 2. install netctl 3. install openvseitch 4. Create a profile ovsbr0: cat /etc/netctl/ovsbr0 Description="Open vSwitch connection" Interface=ovsbr0 Connection=openvswitch BindsToInterfaces=(enp2s0f1) IP=static Address=('193.239.107.34/28') 5. netctl enable ovsbr0 6. systemctl enable ovs-vswitchd.service 7. Reboot Actual Results: ovsbr0 is created, but the device is not in state UP. You have to log in to the server and manually do "netctl start ovsbr0" I am in good luck, as I have a second network adapter configured with netctl. With his, I can log in to the server remotely, even network was broken. For other people it would require a remote console like iLO, to get things working again. It seems to be a question of luck, if the network came up cleanly or not. I guess 5 of ten boots, the network is broken. Sometimes timeing seems to be ok. Expected Results: Cleanly start the network emerge --info openvswitch netctl systemd Portage 2.2.20 (python 2.7.9-final-0, hardened/linux/amd64/no-multilib, gcc-4.8.4, glibc-2.20-r2, 4.1.4-hardened

is this an error in ovs or netctl?
(In reply to Matthew Thode ( prometheanfire ) from comment #1) > is this an error in ovs or netctl? I'm inclined to say netctl from the reporter's description, but I have not really looked into it yet.
Ya, thought the same, just didn't want to waste time looking at it from OVS's side :D
I can't see myself setting up openvswitch just to test this; patches welcome, but send them upstream.
