CentOS 7.x lxc containers on top of CentOS 7.x base host hang. This is perhaps due to wrong config file. CentOS 7.x is more similar to Fedora than CentOS 6.x. CentOS config file is suitable for CentOS 6.x. Hence for CentOS 7.x we need to change config file to fedora after container is created as follows:

  1. Create CentOS 7.x container as usual
  2. After container is created edit its config file '/var/lib/lxc/<container-name>/config' and replace following line 
    lxc.include = /usr/share/lxc/config/fedora.common.conf
    Filename centos is changed to fedora for CentOS7 containers
  3. Start the container with new configuration and now it should work fine.
