The VM disks are in the SAN storage in order to use oVirt we just pointed t= hem to the oVirt VMs. This is how we did it precisely:First we created the = VMs in oVirt with disks which are the same size as the existing disks. then= we deleted these disks which was generated by oVirt and renamed our existi= ng disks to match the deleted ones naming-wise. Finally we started the oVir= t VMs and they were able to run and these VMs are always ok without any iss= ue. The new VMs which have problem are from scratch (no template). One thing th= ough, all these new VMs are created based on an CentOS 7 ISO. We have not t= ried any other flavor of Linux. The kernel 4.1 is actually from Oracle Linux repository since we needed to = have OCFS2 support. So after installing oVirt we updated the kernel to Orac= le Linux kernel 4.1 since that kernel supports OCFS2. | We might need to get libvirt debug logs (and perhaps journal output of th= e host).

The kernel 4.1 is actually from Oracle Linux repository since we needed to = have OCFS2 support.
