The ping test then starts and succeeds because runqemu configures the kernel to bring up eth0 but then some time later connman takes over eth0, which means taking down the interface and bringing it back up again. This behaviour in connman is currently intentional, although I've mailed Marcel to see if they'd be willing to compare the current configuration with the requested configuration and not take the interface down if they match. No amount of systemd dependency-fu can resolve this because connman is "ready" once it has loaded, actually working on the interfaces happens afterwards. One way to mitigate this would be to require N pings from the VM to ensure that the connection has had time to settle. 37207 2 ross.burton 2013-09-25 14:54:07 +0000 Assigning to Stefan who agreed with me and has submitted a patch to do what I suggested. 37285 3 sstncr 2013-09-27 07:58:55 +0000 Patch merged in master http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=41f88ee1dbda44605301dd7309926e04d146ef52 Since we used the nice levels trick on the AB we haven't seen this so I'm not sure if it will fix the problem forever (as the described by Ross the behaviour of connman is intentional), but it should help with false SSH fails somewhat. 37964 4 alexandrux.palalau 2013-10-16 08:11:37 +0000 Switching to verified.
