Specifically: These two things do not work inside i686 containers when the host is running kernel-2.6.18-431.el5.028stab123.1.owl1.x86_64: 1. "ifconfig" inside the containers does not work: root@...tainer:/ # ifconfig SIOCGIFCONF: Bad address 2. Apache 2.2.34 (and 2.2.21) do not start, error_log shows: [Sat Jun 16 14:40:39 2018] [emerg] (14)Bad address: Couldn't set permissions on cross-process lock; check User and Group directives These things work: 1. Everything on the host seems to work normally (like ifconfig). 2. Inside containers, sshd starts and works OK. 3. Inside containers, netstat -nr looks normal. 4. Inside containers, dmesg looks normal, no obvious errors. 5. When I revert the host kernel, containers go back to normal, meaning they works with kernel-2.6.18-419.el5.028stab122.4.owl1.x86_64 This is a minor problem and I am not asking for a solution. I just wanted to mention it in case someone recognizes this problem or if there are any simple things to try. I rebuilt the 431-stab123.1.owl1 kernel with CONFIG_KAISER=n, but I must have done this improperly because the host hung at boot (I editted dot-config-x86_64, then "make PACKAGE=kernel", I know that's not the right way to disable a kernel build-time option, but hey, it sure was easy!) Thanks for listening, ideas welcome, do not think too hard about it. Chris Bopp, Honolulu, HI P.S. May I suggest adding libpopt-devel-static in installorder.conf so the vztemplates can rebuild themselves without a patch?
