i386 userland + x86_64 kernelでlxc-startしたときに上記エラー
下記で暫定対処
#sed -i /usr/share/lxc/config/*.common.conf "-e s/^lxc.seccomp/#lxc.seccomp/" #grep "lxc.seccomp" /usr/share/lxc/config/*common.conf /usr/share/lxc/config/centos.common.conf:#lxc.seccomp = /usr/share/lxc/config/common.seccomp /usr/share/lxc/config/debian.common.conf:#lxc.seccomp = /usr/share/lxc/config/common.seccomp /usr/share/lxc/config/fedora.common.conf:#lxc.seccomp = /usr/share/lxc/config/common.seccomp /usr/share/lxc/config/gentoo.common.conf:#lxc.seccomp = /usr/share/lxc/config/common.seccomp /usr/share/lxc/config/oracle.common.conf:#lxc.seccomp = /usr/share/lxc/config/common.seccomp /usr/share/lxc/config/plamo.common.conf:#lxc.seccomp = /usr/share/lxc/config/common.seccomp /usr/share/lxc/config/ubuntu.common.conf:#lxc.seccomp = /usr/share/lxc/config/common.seccomp
