TL; DR : qcow2 images keep getting corrupted. Any
workaround?<br>
<br>
Long version:<br>
This discussion has already been launched by me on the
oVirt and on qemu-block mailing list, under similar
circumstances but I learned further things since months
and here are some informations :<br>
<br>
- We are using 2 oVirt 3.6.7.5-1.el7.centos datacenters,
using CentOS 7.{2,3} hosts<br>
- Hosts :<br>
- CentOS 7.2 1511 :<br>
- Kernel = 3.10.0 327<br>
- KVM : 2.3.0-31<br>
- libvirt : 1.2.17<br>
- vdsm : 4.17.32-1<br>
- CentOS 7.3 1611 :<br>
- Kernel 3.10.0 514<br>
- KVM : 2.3.0-31<br>

Hello Yaniv,<br>
<br>
We could discuss for hours about the fact that CentOS 7.3 was
released in January 2017, thus not that old.<br>
And also discuss for hours explaining the gap between developers'
will to push their freshest releases and the curb we - industry
users - put on adopting such new versions. In my case, the
virtualization infrastructure is just one of the +30 domains I have
to master everyday, and the more stable the better.<br>
In the setup described previously, the qemu qcow2 images were
correct, then not. We did not change anything. We have to find a
workaround and we need your expertise.<br>
<br>
Not understanding the cause of the corruption threatens us to the
same situation in oVirt 4.2.<br>
