最近在研究docker！在虚拟机centos7中运行docker经常会有：

[jm@localhost docker]$ docker run -it lin/centos6 /bin/bash

2016/11/08 19:38:53 Error resolving syscall name execveat: could not resolve name to syscall - ignoring syscall.

2016/11/08 19:38:53 Error resolving syscall name getrandom: could not resolve name to syscall - ignoring syscall.

2016/11/08 19:38:53 Error resolving syscall name set_tls: could not resolve name to syscall - ignoring syscall.

提示。但是容器的功能都能正常使用。

【解决】

只需要安装或更新软件包libseccomp至2.2版本以上即可消除此报错提示！

[jm@localhost docker]$ sudo yum -y install libseccomp

解决CentOS7下运行docker容器时出现的报错Error resolving syscall name...
