<p class="MsoNormal" style="margin-bottom:12.0pt">Hello to all,<br>
I'm just playing with ovirt4, installed on HP server with CentOS 7, and a virtual machine as host engine.<br>
I have a lot of problems with the server shutdown!<br>
The server dosn't power off and will reboot after some "kernel panic" error.<br>
<br>
To turn off the ovirt server:<br>
1) Put ovirt in global maintinience (hosted-engine --set-maintenance --mode=global)<span style="font-size:10.0pt;font-family:"Courier New""><br>
</span>2) Host engine shutdown and check vm-status<br>
3) Finaly, shutdown server and wait ... wait ... wait<u></u><u></u></p>
