I cannot shutdown virtual machine: it experiences soft lockup and hangs. In console log the following entries can be seen:

PID: 2100   TASK: ffff880037adf500  CPU: 2   COMMAND: "killall5"

There is a bug in linux kernel since 2.6.32-358.18.1.el6 that was ported to Red Hat: 1005866 so it is also presented in all RHEL derivatives as CloudLinux, CentOS and Parallels Cloud Server also.


The workaround is to reset the virtual machine.
