Hi, 

https://pastebin.com/raw/cFrphHHh 

The problematic disk is 
<disk type='file' device='disk' snapshot='no'>
      <driver name='qemu' type='raw' cache='none' error_policy='stop' 
io='threads'/>
      <source 
file='/rhev/data-center/bcc17ec5-3ba3-4664-ba47-24fde9d92a2a/d2f65815-5f25-4740-ba56-76749a0f4571/images/d1db6e0e-87d0-4124-8326-b18bff3fdf90/5974fd33-af4c-4e3b-aadb-bece6054eb6b'>
        <seclabel model='selinux' relabel='no'/>
      </source>
      <target dev='vdc' bus='virtio'/>
      <serial>d1db6e0e-87d0-4124-8326-b18bff3fdf90</serial>
      <alias name='virtio-disk2'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' 
function='0x0'/>
    </disk> 

What can I do? 

Thank you for your time!
