Thanks for your response, I found that the server's kernel has been changed so I installed the official kernel by yum.
but there still question:
/usr/bin/virsh -c lxc:/// start instance-00000011
error: Failed to start domain instance-00000011
error: internal error Child process (PATH=/sbin:/usr/sbin:/bin:/usr/bin LIBVIRT_DEBUG=3 LIBVIRT_LOG_OUTPUTS=3:stderr /usr/libexec/libvirt_lxc --name instance-00000011 --console 27 --handshake 30 --background --veth veth1) status unexpected: fatal signal 11

Sounds like you don't have the LXC driver loaded. Possibably
you don't have libvirt-daemon-driver-lxc installed if you use
libvirt newer enough.

Start the daemon like following will help you find out
the cause.

# LIBVIRT_DEBUG=1 /usr/sbin/libvirtd
# virsh -c lxc:///
