## If it does not succeed, you can do virsh reboot centos command at the server end. 
## reconnection, ACPI installation. acpid service is used to allow hypervisior can restart or shut down the virtual machine 
yum  install - the y-acpid 

chkconfig acpid ON 

## installation Cloud -init. Used to start the virtual machine when nova- meatdata key injection services to the virtual machine.
yum  the install -Y epel- release.noarch
