Hello to all,
I'm just playing with ovirt4, installed on HP server with CentOS 7, and a virtual machine  as host engine.
I have a lot of problems with the server shutdown!
The server dosn't power off and will reboot after some "kernel panic" error.

To turn off the ovirt server:
1) Put ovirt in global maintinience (hosted-engine --set-maintenance --mode=global)
2) Host engine shutdown and check vm-status
3) Finaly, shutdown server and wait ... wait ... wait
