However it can take a while to get it back to CentOS/RHEL. The source of this crash is that you have a "tun0" network interface without IP address and that interface is checked before "ovirtmgmt" and it causes the crash. You can workaround it by removing the "tun0" interface if it doesn't have any IP address.
