I have oVirt 3.1 with two nodes, one of them is running good without restarting the other keep restarting, the maximum uptime that the server can get is 10 days before it restart, I think that it might be something related to the disk.<br>
<br>FYI, the disk are 2 disk of 1TB (RAID-0) to get 2TB.<br><br># /var/log/messages<br>Dec 21 05:28:44 hypervisor01a ntpd[945]: 0.0.0.0 c61c 0c clock_step +17997.588918 s<br>Dec 21 05:28:44 hypervisor01a ntpd[945]: 0.0.0.0 c614 04 freq_mode<br>
