[ovirt-users] shutdown and kernel panic

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 Whats wrong?! -_- best regards Luigi F.
