A Linux system without an acpi management program will suffer failures of soft shutdown. Therefore, make sure that the acpi (power management for Linux) module has been installed on your CVM.
Checking method
Check whether the acpi has been installed using the following command:
ps -ef|grep -w "acpid"|grep -v "grep"
If there's no such process, it hasn't been installed. Then you need to follow the next step to install the module. If there's such process, the next step can be ignored.
Installation method
Use the following command to install the acpi module.
1) For Ubuntu/Debian system
sudo apt-get install acpid
2) For Redhat/CentOS system
yum install acpid
3) For SUSE system
in apcid
Note: The CoreOS system doesn't have such problem.
